This is because of changes to the wording of the question and the addition of new tick-boxes (further details can be found in background notes or in the questionnaire comparability report. The majority of write-in responses for Gypsies and Travellers in 2001 were written under Other White and it is likely that a few may have selected white British or White Irish - though impact is likely to be low as numbers in total for 2001 were around 4,000.3.Comparability issues exist for these groups between 20.Outside the Mixed/Multiple ethnic groups there were high rates of inter-ethnic relationships with White Irish and Other Black.
This article therefore examines inter-ethnic relationships of all people who are in a couple.
Inter-ethnic relationships are defined here as a relationship between people living in a couple who are married, in a civil partnership, or cohabiting and each partner identifies with an ethnic group different from the other partner (within any of the 18 ethnic group classifications used in the census).
The pattern of people in inter-ethnic relationships across the ethnic groups for 20 was broadly similar.
The group that saw the largest change between 20 was Other White where the proportion of people in inter-ethnic relationships decreased by 15 percentage points (from 54% to 39%).
The Other White group is a varied group and it saw the largest growth overall of all ethnic groups between 20 (an increase of 1.1 million, 1.8 percentage points).
It contains more recent migrants who have had less time to establish mixed relationships.These Mixed/Multiple ethnic groups have the youngest age profile of all the ethnic groups.For example, 45% of the Mixed/Multiple ethnic groups were aged under 16, compared with 19% of the overall population.These earlier ethnicity statistics from the 2011 Census focused on the individual.To provide a wider picture of ethnic diversity we can look at mixed ethnicities within the household.The 2011 Census has shown that the population in England and Wales has become more ethnically diverse and all minority groups1 (with the exception of White Irish) have increased in number since 2001.
