How county and district counts relate County figures use the ONS county council row. Districts use their own published rows. Census 2021 counts include disclosure-control changes, so district figures may not add exactly to the county figure. The reconciliation table shows each difference. Census 2011 counts and annual population estimates agree exactly with the district sums.
The 2021 district total is 5 residents lower than the published county total. Both figures are retained as published. The ethnicity table's all-residents count is the denominator for every county ethnic group share.
ONS explains Census 2021 disclosure controls . The audit does not establish the precise cause of each individual difference.
