Counting migrants and groups of migrants
• Migrants move from origins to destinations
• People may move singly or in groups
• Up until the 2001 Census, migrants were counted (in the Census) in two ways
• As individual migrants
• As wholly moving households
A wholly moving household
Wholly moving households or not?
Counting migrants in the 2001 Census
The 2001 Census introduced the concept of the moving group
• Migrants within households are grouped on the basis of their common origins

Migration connectivity
Migration connectivity is a simple measure of how well places are connected to other places
• It is affected by geography, but useful for comparing alternative characteristics given a fixed geography

About the BHPS
The British Household Panel Survey
• A multi-purpose panel survey
• Interviews all adults in a set of representative households
• First wave in 1991: 5,500 households, 10,000 individuals
BHPS: Migrants
The BHPS is a useful source of information about migrants
• Individuals are tracked over many years
• The household context is clear
• Respondents are asked about intentions to migrate, and about reasons for recent migration events
Limitations
• The sample size is small
• The geography is limited
• Migration tends to be a cause of attrition in longitudinal data sets
BHPS data studied
Individuals from wave J (2000-1) were studied
• This roughly matches the transition period over which migration is recorded in the 2001 Census
• The data were linked to the next wave, in order to identify those who had moved during the period

Characteristics of migrants in the BHPS
All respondents are asked when they moved to their present address
• Data are highly dominated by recent moves
• Other moves tend to be within last 10 years or so
• The same pattern is apparent in other waves
