Ethnicity estimates in the Annual Population Survey (APS) have been withdrawn for the April 2010 to March 2011 survey period and are not included in the estimates for the July 2010 to June 2011 period published on 18 Jan 2012.
In 2010 changes were made to the ethnicity questions asked in the APS. These changes have caused problems with producing a consistent time series of estimates for a number of the variables published on Nomis.
Further analyses are currently taking place and ONS hopes to be able to make ethnicity estimates available for the affected periods within the next few weeks. ONS apologises for any inconvenience.
