The MICS3 Process
By now we have decided to do a MICS3
We have answered these questions:
Why is the survey being done?
How will the survey results be used?
To whom will the survey results be addressed?
Objectives
An overview of the entire survey cycle
To review the key decisions for survey organisers
Critical steps and sequences
How decisions in one area affect other survey areas
Main activities
1) Definition of survey instruments2) Pretest the survey instruments3) Sampling (presentation)4) Main training (presentation)5) Fieldwork (presentation)6) Data processing (presentation, workshop)7) Data analysis and report preparation
(presentation and workshop)8) Dissemination of results (presentation and
workshop)9) Archiving and further analysis
Decisions to make before starting
Identify survey coordinator and key senior personnel
Decide on level of aggregation and sample size Calculate the number of interviewers required
and days needed in the field Establish a timetable Calculate how much the survey will cost
Review all items above to match budget!
Key survey personnel
Survey coordinator Senior technical persons and institution(s) Sampling expert Field work coordinator Data processing supervisor Steering committee
Level of aggregation for estimates
National Level 6,000 households, 300 clusters relative error of 12% or less
Subnational Estimates Regions Urban and rural Provinces or states Other population groups of interest
COSTS
Factors influencing cost
Unit and total costs vary considerably across countries
Depend on a variety of factors, including sample size labour costs currency fluctuations etc.
Main component: fieldwork expenditures
Factors influencing fieldwork costs: example
Sample size: 6,000 households Each interview takes 60 minutes plus 10 minutes to
move from house to house (70 minutes total) depending on questionnaire length!
Working day is 6 hours (or 360 minutes) excluding lunch break and transport to and from cluster
Thus 360 / 70 = ~5 households per interviewer per day (also allows for call-backs)
6,000 / 5 = 1,200 interviewer days required
Variables in field work
Three variables to adjust to determine best combination of interviewers and time frame Number of interviewers Number of days of field work Size/number of teams
Options: 30 days of fieldwork x 40 interviewers 35 days of fieldwork x 35 interviewers 40 days of fieldwork x 30 interviewers
Timetable
When to start? Major reports, other surveys, weather
Good Planning What do we need to learn from MICS? Uses of the data
Tasks 1 2 3 4 5 6 7 8 9 10 11
Identify resource person and survey coordinator, plan survey
Adapt and pretest questionnaires
Carry out sampling
Complete logistic arrangements
Select and train interviewers
Conduct pilot study and collect data
Enter and clean data
Complete data processing
Prepare reports (preliminary and final)
MonthsTimetable for a survey of 6,000 households
Assumptions: 6,000 households; interviewer completes 5 households per day; 1,200 interviewer-days;30 interviewers; 40 days in the field; plus 7 days for one day off per week; plus transport days = 54 days
