Title Population estimates by single year of age, sex and ethnic group for council areas in Scotland, 1991-2001 
Description The study comprises complete mid-1991 and mid-2001 population estimates by single year of age, sex and ethnic group for Council areas in Scotland. Although census output from both 1991 and 2001 provides a detailed account of the population with an ethnic group dimension, and with detail of age and sex, accurate analyses of population change for sub-national areas are subjected to a number of problems that make comparisons of populations over time difficult. These include changes in the population definition, changes in the treatment of non-response, changes in ethnic group classification and age standard outputs, and changes in geographical boundaries for standard census output. A standard methodology has been implemented to overcome these four challenges, and to derive a consistent population time series 1991-2001, with age detail (single year of age or quinary ages), sex and ethnic group. These population estimates are made available using the 2001 Census geography for each district in Scotland. The methods have focused on ensuring consistency with the statistical agencies' latest estimates of mid-1991 and mid-2001 populations estimates published in 2004 without an ethnic group dimension, as well as with the mid-2001 population estimates published in 2006 with an ethnic group dimension.

Type Of Material Database/Collection of data 
Year Produced 2009 
Provided To Others? Yes  
Impact The provision of population time series data for council areas by age, sex and ethnic group officially complements UK Census aggregate data and represents an important knowledge transfer activity, with many policy and governance users including National Records of Scotland.

Title Population estimates by single year of age, sex and ethnic group for sub-national areas in England and Wales, 1991-2001 
Description Although census output from both 1991 and 2001 provides a detailed account of the population by age, sex and ethnic group, accurate analyses of population change for sub-national areas are subjected to four separate problems that make comparisons of populations over time difficult: changes in the population definition, changes in the treatment of non-response, changes in ethnic group classification and age standard outputs, and changes in geographical boundaries for standard census output. A standard methodology has been implemented to overcome these four challenges, and to derive a consistent population time series 1991-2001, with age detail (single year of age or quinary ages), sex and ethnic group. These population estimates are made available using the 2001 Census geography for each district, ward and Output Area in England and Wales. The methods have focused on ensuring consistency with the latest population estimates from ONS for 1991 and 2001. Further information can be found on the Cathie Marsh Centre for Census and Survey Research web page and the ESRC Award web page.

Impact The provision of population time series data for small areas by age, sex and ethnic group officially complements UK Census aggregate data and represents an important knowledge transfer activity, with many policy and governance users including Birmingham City Council.
