Problems of changing definition and availability - 2

• No breakdown of migrants from outside UK by region/country of origin in 2001

• New concept of moving group in 2001: i.e. a single person or a group of people within a household who moved together from the same usual address one year before census day (though ‘wholly moving household’ element retained)

• Inclusion of students in the sense of people migrating to, from and at place of study (as result of treating term-time address as usual address in 2001, cf parental/vacation address in 1991)

Notes:

The problems in the definition of variables stem from:

new tables in 2001 for family status and occupation

no marital status table in 2001

new categorizations of variables used in 2001 e.g. for ethnicity

no breakdown of immigrants by region of origin in 2001

new concept of moving group in 2001

inclusion of students in 2001 data
