    1. INTRODUCTION: PURPOSE OF THE MIFARE SURVEY

    The MIFARE project (“Migrants’ Welfare State Attitudes”) is a comparative survey among

    immigrants in Europe which focuses on welfare state attitudes. The MIFARE project is funded

    by the NORFACE research programme Welfare State Futures. Coordinated by Marcel Lubbers

    (Radboud University Nijmegen), the MIFARE project has been conducted by researchers at

    Aalborg University, University of Amsterdam and University of Konstanz.

    The MIFARE study is the first cross-national survey that focuses on immigrants’

    attitudes towards the welfare state. In Europe, the field of research on welfare state attitudes has

    paid little attention to the perspective of immigrants. Due to migrants’ socialization in different

    welfare regimes, and their often disadvantaged socio-economic positions, the immigrant

    perspective provides a unique opportunity to test the central theories in the field on the role of

    self-interest (Andreß & Heien, 2001; Gelissen, 2002; Van Oorschot, 2006; Jaeger, 2006b;

    Svallfors, 2012), group-loyalty (Esser, 2009; Maliepaard, Lubbers & Gijsberts, 2010) and of

    socialization in different welfare regimes (Esping-Andersen, 1990; Jaeger, 2006a; Larsen,

    2008; Jaeger, 2009; Van der Waal et al., 2013). The MIFARE study aims to study immigrants’

    welfare state attitudes, and to explain differences across migrant groups, as well as differences

    compared to the overall public opinion in the country of origin and the host country.

    In order to study migrants’ welfare state attitudes, and to explain differences across

    migrant groups new data are collected. The questions used in this new survey are partly based

    on the ISSP 2006 questionnaire “Role of the government”, the ESS 2008 questionnaire

    “Welfare state attitudes” and new questions which were piloted first. This document describes

    the data collection, the representativeness, the questions and response of the MIFARE survey.

    2. RESEARCH DESIGN

    The MIFARE survey was designed to focus on immigrants who migrated to the receiving

    country at an age of 16 years or older, from different origin countries across three European

    countries. Efforts were taken to harmonize the data collection across the three countries under

    study. In this chapter the research design and the rationale for the selection of countries and

    groups included in the study is described (section 2.1). The sampling strategy and the method

    of drawing the sample are presented separately for each country (section 2.2). The survey mode

    is addressed in more detail in the last section of this chapter (section 2.3).

    2.1 Research design and selection of countries and groups

    The MIFARE survey has been conducted in three countries: Denmark, Germany and the

    Netherlands. All three countries have the opportunity to sample from population registers,

    including immigrants. The opportunity to sample randomly from the registers enables us to test

    for representativeness of the survey, to approach migrant groups that are smaller in number,

    and guarantees comparable designs in the three countries. We proposed to sample immigrants

    from the age of 18 and older, and a native control group (to be able to compare between migrants

    and natives also for the questions specifically developed for the proposed survey). We chose 4

    intra-EU origin countries and 6 extra-EU origin countries, including the most numerous migrant

    populations: (first generation) immigrants from Poland, Romania, Spain and the UK for the

    intra-EU origin countries. As for the extra-EU origin countries, we selected China (mainland

    only, excluding Hong Kong), Japan, Turkey, the Philippines (not in Germany due to sampling

    issues), Russia, and the US. China and Turkey are the only countries not included in either the

    ISSP or ESS when the welfare-state attitudes rounds were conducted.

    2.2 Sampling strategy and sampling method

    The sampling method chosen in the three countries depended on the national data sources

    available to identify immigrants. Although data from local or central registry offices could be

    used in all countries, there are differences in the possibility to select on migration age, which

    affects the sampling strategy. Since tailored sampling strategies were used in each country, the

    sampling procedure is described in separate sections for the Netherlands (section 2.2.1),

    Denmark (section 2.2.2) and Germany (section 2.2.3).

    2.2.1 The Netherlands

    In the Netherlands, migrants who stay for longer than 4 months are required to register at the

    municipality. Statistics Netherlands (CBS) sampled the immigrants from these municipality

    based registrations. The aim was to have 300 questionnaires filled out per immigrant group and

    natives. Based on other surveys in the Netherlands, Americans, Brits, Dutch natives, Japanese

    and Spaniards were expected to have a response rate of 33.3%. While Chinese, Philippines,

    Polish, Romanian, Russian and Turks were expected to have a lower response of 27%. These

    expectations resulted in a sample of 900 immigrants from the first mentioned groups, and a

    sample of 1100 from the last country of origin groups listed.

    The sample for the survey is a stratified sample, one stratum for the native Dutch and

    one stratum for each of the ten migrant groups. From each stratum a simple random sample

    without replacement was drawn. Since people between 18 and 75 years were selected it was

    possible that immigrants from the Soviet Union were selected. Statistics Netherlands had also

    information on the area in which migrants from the former Soviet Union had lived. Only

    immigrants from the Soviet Union who lived in what is now Russia are selected.

    From the sample that was drawn, Statistics Netherlands successively requested the

    names and addresses from the National Identity Data (RvIG). When it turned out that a selected

  • 9

    person at an address had already been approached for a regular CBS survey in the last year,

    then this person was removed from the sample. If a person lived at an address of an institution

    then the person was also removed from the sample. The sample was drawn on October 23th

    2015, 2 weeks before the first invitations were sent.

    Table 2.1 provides an overview of the group sizes in the Dutch population and in target

    population size in the MIFARE sample.

    1 The sample of migrants from Russia is drawn from the population with a Russian origin; not all may have been

    born in Russia. Additional information about these migrants is used to select only those who were born in what

    is now called Russia.

    2.2.2 Denmark

    All immigrants who have stayed in Denmark for more than three months, and have a

    permanent housing, can apply for the status of living in Denmark in the Civil Registration

    System (Det Centrale Personregister or CPR-register in Danish). This is unless they have a

    residence permit, which is necessary for migrants from some countries, in which case status

    of living can be applied for from the first day. The Danish respondents were sampled, using

    the Civil Registration System among Danes, and ten migrant groups. For the Danes the

    sample was drawn randomly from all who are born in Denmark, both parents are Danish

    citizens, at least 18 years old and are living in Denmark. For the migrant groups the sample

    was drawn randomly based on the following criteria:

  • 10

    • The respondent must be born abroad, in one of the ten selected countries

    • The parents of the respondent cannot be Danish citizens at the time they migrated to

    Denmark, that is, when the respondent obtained living status.

    • The respondent must be at least 16 years old when they migrated to Denmark

    • The respondent must have lived in Denmark (living status) for at least 12 months.

    The aim was to have 300 filled out questionnaires per migrant group and natives. Based on an

    expectation of higher non-response in some groups 900 Danes, Americans, Brits, Japanese

    and Spaniards where sampled, while 1000 Chinese, Philippines, Polish, Romanian, Russian

    and Turks where sampled (Font & Méndez, 2013). Only migrants from the Soviet Union who

    lived in what is now Russia are selected. Similar to the sample from the Netherlands this is

    also a stratified sample drawn separately among the natives, in this Danes, and the ten migrant

    groups. The sample was drawn in October of 2015 and therefore less than a month before

    fieldwork begun. Table 2 provides an overview of the group sizes in the Danish population

    and in the targeted MIFARE sample. For the Danish sample the name and address was

    provided.

    Table 2.2 shows that the sample sizes and the total population in some cases are not

    very different, e.g. among the Japanese immigrants. Furthermore, the total populations

    reported below are “too large”, in the sense that list drawn from Statistics Denmark online

    database cannot include all the selection criteria listed above. The result of this is that we

    sampled almost all Japanese who fit the criteria, and large parts of the Spanish and Russians

    living in Denmark.

    Migrants are born abroad. No parents are Danish citizens born in Denmark. If there is no information

    on any of the parents, and the person is born abroad, the person is counted as a migrant. Note that is

    not fully identical with the sampling criteria described above.

    2.2.3 Germany

    In Germany, migrants are required to register after 2 months of stay at their municipalities.

    Registration data are not available on national level but have to be acquired from each

    municipality separately. No information is provided for date of migration which led to over-

    sampling in order to sample a sufficient number of migrants who migrated after the age of 18.

    To get a sample that is most likely to represent the whole population of the respective migrant

    (and native) group, we decided to cluster communities according to their size. Since we do not

    want respondents from bigger cities exclusively, we also added smaller communities. We

    decided to divide all German communities into four clusters (500k). In a second step we used data from the Mikrozensus 2011, which was the newest

    dataset when it comes to individual characteristics for all German communities.

  • 12

    To make our sample representative, we decided to sample only in those communities of a

    certain size, where at least 10% of a migrant group is living (e.g. Chinese only from

    communities with at least 100000 inhabitants).

    Table 2.3: Distribution of migrant groups in Germany, by size of municipality Community Size

    500k 26.7% 17.7% 100.0% 31.0% 100.0% 18.8% 100.0% 100.0% 82.2% 18.6%

    TOTAL 100.0% 100.0% 100.0% 100.0% 100.0% 100.0% 100.0% 100.0% 100.0% 100.0%

    Source: Microzensus 2015

    Table 2.3 shows how many immigrants of each group should be sampled in the respective

    community size. We decided to sample those groups proportionally that the sample represents

    whether a group is rather living in big communities or not. Hence, around 27,5% of our Polish

    sample should be drawn from municipalities who count less than 50 000 inhabitants.

    For each group, we want to have 3 communities per group. We decided to choose those

    communities where most people of each group are living. In cases, where we were not able to

    obtain data we chose the community which was next on the list. After obtaining the data from

    the communities, we sampled the respondents proportionally to their group size in the

    respective city. Also, we limited the sample to communities who are in West Germany and

    excluded communities which are part of the former German Democratic Republic.

    Furthermore, we had to consider that respondents end up in the sample that have not migrated

    before the age of 18 or even second generation immigrants. Therefore, we oversampled for

    each community with the respective factor of having such respondents in the sample. In a

    final step to decide the group size, we oversampled certain groups due to previous research

    indicating a lower response rate such as migrants from Turkey or Poland.

    1 The sample of migrants from Russia is drawn from the population with a Russian origin; not all may have been

    born in Russia. Additional information about these migrants is used to select only those who were born in what

    is now called Russia.

    2.3 Survey mode

    Postal surveys were conducted in all countries. Respondents were invited by mail to participate

    in the survey. The invitation letter was bilingual; in the language of the country of residence

    and in the language of the country of origin of the respondent. Respondents could participate

    by filling out a written questionnaire which was sent with the invitation. Or respondents could

    participate via Computer Assisted Web Interviews (CAWI ); the interviewee completed the

    questionnaire supplied to them via a website link with an unique login code.

    3. SURVEY INSTRUMENTS

    In order to collect comparable data across the four countries the team developed a harmonized

    survey instrument. Apart from a few questions that were asked exclusively in selected countries

    or for specific ethnic groups, identical questions were asked in the Netherlands, Denmark and

    Germany. Many of them were adopted from established survey instruments, such as the

    International Social Survey Program, or the European Social Survey. This facilitates

    comparisons with other studies.

    Since it was anticipated that migrants were not all able to fill out a questionnaire in the

    receiving country language, the questionnaire was translated into immigrants’ native languages.

    It was assumed that this would reduce the non-response and would increase the accuracy of

    answers. This procedure included processes of translation and re-translation for testing the

    correct meanings of the questions in different languages.

    In the next sections, the topics in the questionnaire are discussed (section 3.1), the

    variation in the questionnaire between the Netherlands, Denmark and Germany (section 3.2).

    Section 3.3 describes how the questionnaire for native differs. Finally, section 3.4 outlined the

    pre-test which was done in Germany.

    3.1 Topics of the questionnaire

    The questionnaire covered a broad range of topics:

    A. Demography and migration biography

    B. Government responsibilities

    C. Household and Health

    D. Language and Contacts

    E. Religion

    F. Media use and Political attitudes

  • 15

    G. Knowledge and opinions about welfare state use

    H. Experiences with residence country

    I. Education and employment

    J. Household assets

    In the first module, the respondents were asked about demographic characteristics and questions

    about their migration biography. The second module asked respondents’ opinion about the role

    of the government in the receiving country. The third module covered respondents’ household

    situation in the receiving country, respondents’ health, the health of their household members

    and relatives and the experience and satisfaction with health care services in the receiving

    country. The fourth module addressed language proficiency and social contacts with natives,

    other immigrants and people from the country of origin. In the fifth module, the respondents

    were asked about their religious affiliations, beliefs and practices. The sixth module covered

    respondents’ media usage, both from the country of origin and receiving country. As well as

    respondents’ political attitudes, including party preference, opinion about taxes, the right

    migrants should have to vote and the role the EU should have. In the seventh module

    respondents were asked about their actual knowledge about the welfare state rights migrants

    from their country of origin have, as well as the rights of EU and non-EU migrants have. In

    addition to the actual knowledge also the opinion about these rights were asked. In the eighth

    module topics about discrimination experiences and the role migrants have in the receiving

    country were covered. The ninth module looked into migrants’, and their possible partner’s,

    education and employment history. Finally, the tenth module examined migrants’ earnings, and

    the use of welfare state benefits in their household. On average, the fill out a survey lasted about

    25 minutes.

    3.2 Challenges of translation and national adaption

    The master questionnaire was constructed in English. Native-speakers, hired via the translation

    agency “VVH translations” translated the English version into the different immigrant

    languages. To control the quality of the translations, re-translations were performed by the

    translation agency. During the process of constructing, translating, and pretesting the

    questionnaire, further national and group specific adaptations were made. A major challenge

    was related to the different welfare state arrangement in Denmark, Germany and in the

    Netherlands. Some welfare state arrangements were present in one of the countries only, for

    example, only the Netherlands has the 30% tax rule for immigrants. While other arrangements

    have a, slightly, different meaning in the three countries. For example, what in the Netherlands

    is known as social assistance, is something different in Germany. The Dutch social assistance

    is called “Hartz 4” in Germany. So, there are differences in the number of welfare state

    arrangements between the survey countries. And in some cases, the names of the arrangements

    look different but content-wise relate to the same form of arrangement.

    3.3 Questionnaire for natives

    Besides respondents from ten different countries, also natives from Denmark, the Netherlands,

    and Germany were included in the survey. Questions regarding migration history, perceived

    discrimination and identification were straightforwardly not asked at natives. In general, the

    wording of the questions for natives was adjusted such that they could not derive from the

    questionnaire that it was a study on migrants.

  • 17

    3.4 Pre-test

    To test whether the questions were understood by a larger group, to check the mailing

    coordination from one country, the Netherlands, and to make a very limited prognosis about

    the influence of an unconditional incentive a pre-test was done in the German city Freiburg

    among native and American immigrants in August and September 2015.

    The aim of the national pre-test in Germany was not only to obtain information about

    potential pitfalls of the questionnaire, but also to get more information about how the sampling

    procedure works for Germany. Since in Germany, researchers had to contact every municipality

    we got useful information about the procedure of how to get in touch with the municipalities

    and how to contact them most efficiently. We decided to field two versions of the questionnaire,

    one for the native Germans and one for American immigrants. Furthermore, we obtained

    information about the different measures we wanted to apply to the full sample, like variance

    and item non-response. Additionally, information about the response rate, not deliverable mails

    and other logistic problems was obtained. In what follows, we discuss the sampling, fieldwork,

    and the response (section 3.4.1), as well as the actual questionnaire fielded (section 3.4.2).

    3.4.1 Pre-test: Sampling, Fieldwork, and Responses

    We decided to field the questionnaire in a large city that would not be in our actual sample,

    since the immigrant group would be likely to receive the pre-test version as well as the actual

    version of the questionnaire. The city of Freiburg (around 225,000 inhabitants) was one city

    that matched the requirements. Additionally, the close distance to Konstanz would allow us to

    also travel to the city if something would go completely wrong, which was not necessary in the

    end. After the contact with the municipality we received a dataset containing the address data

    to launch the pretest. We obtained the random address data of 100 native Germans and 200

  • 18

    American immigrants. As in the main study, the questionnaires were printed by the Dutch

    company I&O Research. They were also responsible for the fielding by sending the mail to the

    potential respondents. The procedure was carried out according to Dillman (2000), by sending

    a postcard as a first reminder one week after the respondents had received the invitation. A

    second reminder containing the questionnaire and a letter was sent two weeks after the first

    reminder. Every participant was offered a 10€ voucher of their choice (Amazon, Media Market,

    Müller).

    We started to send the invitation letter containing the questionnaire and the invitation

    code for the online version on August, 10th 2015, followed by the first reminder on August 31st

    2015. The second reminder was then sent on September 14th 2015. We were not able to track

    the time of return, since the post office in Konstanz just delivers the mail once a week. Also for

    those who participated using the online version, information about response date and response

    time was not obtained.

    American 200 85 (42.5%) 54 27% 47.8%

    Total 300 87 (29%) 102 34% 47.9%

    Looking at the returns and responses we must state that for the Americans 29% of the letters

    could not be delivered. For the Germans, we did not have those problems (2%). We assume that

    besides immigrants being a more mobile group (return migration) we additionally could have

    the problem that some of the potential respondents are exchange students, who have returned

    to America. This is likely since Freiburg is known as a university town. Hence, a large share of

    an uncommon immigrant group for Germany as the Americans might be consisting of students.

    Since the new semester starts in October it is likely that American students left the country in

    the time between we received the address data and the time the questionnaire was fielded.

    Nevertheless, the response rate indicated a high response rate. The actual response rate for

    native Germans and for Americans is close to 50%. The high response rate might be a result of

    the topic we are asking; it is higher than most other surveys conducted in Germany.

    3.4.2 Questionnaire

    The aim of the pre-test was also to get more insights on problems that arose within the

    questionnaire. In conclusion, we adjusted the order, added, rephrased, and omitted questions

    according to the results. The questionnaire contained the following modules:

    A. Demography and migration biography

    B. Government responsibilities

    C. Household and Health

    D. Language and Contacts

    4. FIELDWORK

    Despite frequent team meetings and central coordination, the data collection could not be done

    in exactly the same way in all countries. Partly due to different sampling strategies (see section

    2.2), and due to different strategies to increase the response rate. In this chapter, the cross-

    country time frame of the data collection is summarized (section 4.1) followed by details on the

    coordination of fieldwork (section 4.2). Country specific approaches to increase the response

    rate are discussed in section 4.3. The final section briefly outlined the strategies to check if the

    questionnaire was filled out by the invited respondent (section 4.4).

    4.1 Time frame of the fieldwork

    Although the initial planning was to have the same fieldwork period in Denmark, Germany

    and the Netherlands, due to an extended sampling period in Germany, the German fieldwork

    was later than the Dutch and Danish period. Table 4.1 provides an overview of the fieldwork

    period in the Netherlands, Denmark, and Germany.

    Germany December 8 2015 December 13 2015 February 5 2016 April 2 2016

    With the first mailing, all respondents received an invitation letter to participate in our

    research. This letter also included the website reference and unique login code to participate

    online. In addition to this login code, respondents received two questionnaires; one

    questionnaire in Danish, Dutch or German and one questionnaire in respondents’ mother

    tongue.

    The first reminder was delivered five days after the invitation. The first reminder was a

    (fancy) postcard that contains a reminder to participate, together with the website address and

  • 22

    login code to participate online (straightforwardly, natives only received the questionnaire in

    Danish, Dutch, or German). Since there was limited time between the invitation and the first

    reminder there was a likelihood of cross posting (respondents who already participate still

    received a reminder), which was noted in the text.

    The second reminder contained a reminder letter and again the two questionnaires. Since

    the likelihood that migrants visited their families in that period the decision was made to

    postpone the second reminder after the Christmas holidays. Due to some difficulties with the

    German mail the second reminder was delivered in Germany on February 5th. In the Netherlands

    and Denmark, the data collection was closed four weeks after the second reminder. In Germany,

    this period was extended to seven weeks due to a lower response and the weekly, instead of

    daily in the Netherlands and Denmark, mail delivery at the university.

    4.2 Coordination of the fieldwork

    Because of the budget, the data fieldwork was done as much as possible by the universities

    itself. For pragmatic reasons the coordination was done by the Radboud Univeristy. Although

    coordination with the fieldwork agency was done by the Radboud University, the Danish and

    German university provided the input to the fieldwork company directly about the respondents

    who needed a reminder and who not.

    The online questionnaire ran on a server at the Aalborg University. The three countries

    were each responsible for creating a national file of the online response.

  • 23

    4.3 Strategies to increase response rate

    To increase the response rate both in the Netherlands and Denmark a conditional incentive was

    used. In Germany, an experiment with none, a conditional, an unconditional and the

    combination of conditional and unconditional incentives was implemented.

    4.3.1 The Netherlands

    To increase the response rate in the Netherlands, a conditional incentive was used.

    Respondents who participated could choose to receive a 10-euro gift voucher from three

    (online) shops: Blokker, Bol.com, and Hema.

    4.3.2 Denmark

    To increase the response rates in Denmark a conditional incentive of a movie ticket valued at

    75 DKR (10 euro) was used. The incentive was sent out digitally after the collection of the

    survey was completed.

    4.3.3 Germany

    For the incentive experiment, respondents were grouped into either receiving an unconditional

    incentive only, an unconditional and conditional, a conditional incentive only or no incentive

    at all. The unconditional incentive was a small handy-cleaner with the Konstanz University

    Logo imprinted. For the conditional incentive, respondents who participated could choose

    between a 10€ voucher from Amazon, Media Markt, or Müller.

    After the first and second reminder, the response rate of people who received either none or

    only the conditional incentive was rather low (around 11.3%) compared to the groups which

    were promised a voucher (around 15%) which led to the decision to offer these groups a

    voucher as well in order to boost response rates after the second reminder.

    5. RESPONSE RATES AND SELECTIVITY

    The response rate is defined as the proportion between the number of respondents who

    participated by filling out the questionnaire online or by paper and pencil in relation to the

    number of people approached (sample). In this section, a brief overview of the sample sizes and

    response rates across all countries is given (section 5.1). Based on this, response rates for each

    country are described in more detail (see section 5.2 for the Netherlands, section 5.3 for

    Denmark, and section 5.4 for Germany).

    5.1 Overview of response rates across all countries

    Table 5.1 shows the overall response rate after cleaning for the Netherlands, Denmark, and

    Germany. For the Netherlands and Denmark, the response after cleaning is almost equal in

    both countries, where Denmark has a 1.65% higher response than the Netherlands. Germany

    has with a response of 18% the lowest response rate In section 5.2., 5.3, and 5.4 the response

    rates will be discussed in more detail.

    Table 5.1: Sample size, response and response rates

    Netherlands Denmark Germany

    Sample size 11100 10500 13561

    Response 3672 3647 2234

    Response rate 33,1% 34,7% 18,2%

    5.2 The Netherlands

    The overall response rate of 33.1% in the Netherlands, which is relative high in comparison

    with other surveys among immigrants in the Netherlands (Andriessen & Kappelhof, 2016;

    Korte & Dagevos, 2011). Table 5.2 shows that there are large differences in response between

    migrant groups though. The response among native Dutch is the highest with 47.4%. The

    response from immigrants from Russia is with 43.18% almost as high as the response among

  • 26

    natives. The response from the Turks is the lowest, 19.3%, which resembles other surveys

    among Turkish immigrants in the Netherlands (Andriessen & Kappelhof, 2016; Korte &

    Dagevos, 2011).

    The expectation was that Americans, Brits, Japanese and Spaniards would have a

    response rate around 33.3%. While Chinese, Philippines, Polish, Romanian, Russian and Turks

    were expected to have a response around 27%. Americans (27.89%) and Brits (29.89%) have a

    somewhat lower response rate than expected. While the other groups, with exception of the

    Turks, have a (much) higher response rate.

    Table 5.2 also shows the difference between the response before cleaning and the

    response after cleaning. The differences are almost equal between all groups, and are caused

    because some people filled out the questionnaire twice (online and hard copy), or that a partner

    of the respondent also filled out the questionnaire. In section 6.1 the data cleaning will be

    discussed in more detail.

    Finally, table 5.2 shows that in general more than seventy percent of the questionnaires

    are filled out by paper and pencil and less than thirty percent online.

    Table 5.3 shows the selectivity of the response in relation to sex and age. It appears

    that significant more Chinese, Japanese and Polish women filled out the questionnaire than

    expected on the male female ratio in the sample. Regarding age, native Dutch, Chinese,

    Japanese, Brits and Americans who participate are significant older than native Dutch,

    Chinese, Japanese, Brits and Americans in the sample.

    Sample Response

    Table 5.4 combines above descriptive results by showing the results from logistic

    regression analyses predicting various reasons for participating. The results show to what extent

    people with certain characteristics in the sample are more or less likely to participate than

    others. Women are more likely to participate than men. The same applies for older people.

    Native Dutch are more likely to participate than other ethnicities.

    5.3 Denmark

    As shown in Table 5.1 the overall response for Denmark is 34,7 per cent, which is very

    similar to the results from the Netherlands, and must considered good considering that

    migrants surveys often have lower response rates than surveys of the general population (Font

    & Méndez, 2013). Table 5.5, below, shows the differences in response rate between the Danes

    and migrant groups.

    The goal was to get at least 300 respondents in each group, which we have not quite

    succeeded in, since there are fewer from Turkey, Poland, Romania and the Philippines. These

    are all groups with oversampling, but in retrospect this should have been higher in these

    groups. For Russians and Chinese the oversampling was, however, not needed, as there were

    over the 300 with good response rate. Generally, looking at response rates they were

    relatively high, with over 40 per cent, for Russians, Danes, Brits, and Japanese. On the other

    hand, they are relatively low for Turks and Romanians, which was as expected.

  • 30

    Table 5.5 also shows the difference between the response before cleaning and the

    response after cleaning. The differences are almost equal between all groups (between 9 and

    24), and are caused because some people filled out the questionnaire twice (online and hard

    copy). When duals existed they were compared, and if both where filled out, paper where

    preferred over online. Finally, the table shows that paper questionnaires was generally

    preferred by about two third of respondents, while about one third used the online option.

    Though there is a little variation between the group this pattern is quite persistent

    5.3.1 In depth non-response analyses Denmark

    Using register data, in Denmark it was possible to compare respondents to the full population

    regarding to gender, age, household type, citizenship, labour force position, social economic

    position, income, received benefits and migration history. The differences between respondents

    and non-respondents are remarkably small. There are some differences between respondents

    and non-respondents on labour market position and other socioeconomic factors none of them

    are remarkably different, and often they vary between group, e.g. unemployment leads to higher

    response rates for some groups and lower for other. Tables 5.6 to 5.18 compare the respondents

    with the non-respondents in Denmark.

    5.4 Germany

    The overall response rate in Germany was 18.15% which was lower than expected. The

    response rate was highest among native Germans, migrants from China, Spain and the UK

    with overall 28%. Response rates were particularly low for migrants from Poland (16.25%)

    and Turkey (10.85%). Overall, respondents preferred pen and pencil over the online tool.

    Looking at the response rate by incentive group we see that we achieved the highest response

    rate when people were promised a voucher in case they would participate in the study. The

    unconditional incentive, however, had almost no effect on the response rate.

    Table 5.20 combines above descriptive results by showing the results from logistic regression

    analyses predicting the likelihood of participation. We see that women are on average more

    likely to participate then men. Also, the chances of participation increases the older people are.

    With regards to ethnic differences we find mixed results; whereas migrants from China, Spain

    and the UK were more likely to participate than natives, migrants from Poland, Romania,

    Russia and Turkey were less likely to participate. No differences between migrants and natives

    were found for Japan and the US.

    Lastly, we observe that for all groups the unconditional incentive had no effect on the response

    rate whereas the conditional incentive raised response rates at least for migrants from china and

    the UK.

  • 6. DATA PROCESSING

    6.1 Data cleaning

    The survey design made it possible for respondents to fill out the questionnaire both online and

    by paper and pencil. In addition, cross-posting, due to the limited time between de invitation

    and reminders, could result in that respondents received the written questionnaire twice (with

    the invitation and with the second reminder), which could have the effect that they handed in

    the questionnaire twice. Double, or even triple responses are deleted, using the following

    strategy. The least complete and, or latest returned questionnaire was deleted. In case of a fully

    completed paper and pencil questionnaire and a fully completed online questionnaire, the online

    questionnaire was deleted, assuming that the paper and pencil questionnaire is in general filled

    out with more attention than the online questionnaire.

    The survey design made it also possible that other than the invited person filled out the

    questionnaire. During the data cleaning a check on sex, date of birth and ethnic background was

    provided to ensure that the invited respondent is included in the dataset.

    Finally, limited completed questionnaires, with less than half filled out, were also

    deleted from the dataset. In the Netherlands the data cleaning resulted in deleting 250 entries

    (6.37% of the initial response). And in Denmark 173 entries (4,52% of the initial response)

    were deleted.

    6.3 Constructed variables

    Some variables in the MIFARE dataset are constructed, such as age and ISCED score. In this

    section the construction of these variables is discussed.

    We added a unique respondent number respondent id to the data. Moreover, we added

    the variable country of origin co to the dataset, which indicates the country of origin of the

    respondent according to the population registers. Receiving country rc indicates whether a

    respondent lives in Denmark, the Netherlands, or Germany. Mode indicates if the respondent

    filled out the questionnaire online or offline. And if offline if he or she filled out the

    questionnaire in the mother tongue or in Danish, Dutch, or German.

    Finally, based on the highest completed education in both the country of origin and the

    receiving country we created three ISCED variables. One ISCED score for the highest

    educational level in the country of origin, isced_co. One ISCED score for the highest

  • 48

    educational level in the receiving country isced_rc. And one ISCED score for the overall

    highest educational level, isced. Appendix C shows how the ISCED variables are created.

    6.4 Open-ended questions

    Except of yborn (in which year are you born), edu_age (age of completed fulltime education)

    and moveto (in which year did you moved to RC), the open-ended questions have not been

    coded for the current release of the data. For privacy and practical reasons the text entries for

    open-ended questions are not available in the public release data file. Please contact the research

    team at [email protected] should you want to use the open-ended questions.

    7. QUESTIONNAIRE

    In this section the questionnaire is given question by question. Variable categories are in

    accordance with the categories in the MIFARE data set. Where RC is used, Denmark, the

    Netherlands, or Germany should be read, depending on the country in which the questionnaire

    was conducted. If CO is used, the country of origin of the respondent should be read. Moreover,

    sometimes as condition is mentioned “asked to natives only”, or “not asked to natives”. In

    Denmark natives means people who are born in Denmark; in the Netherlands natives means

    people who are born in the Netherlands; and in Germany natives means people who are born in

    Germany. In addition, open-ended questions are shown, although these are not in the MIFARE

    data set.

    Below an example of how the questions are described is given.
