General description
This dataset provides the components of change within the official population estimates for the local authorities in Wales. These estimates are consistent with the results of the 2011 Census and show the contributions that natural change (births less deaths); different elements of migration and other smaller adjustments make to the changing population estimates in each local authority over the period since 1991.

Data reference periods
Data are produced and reported annually and relate to the change between 30 June of successive years from 1991 onwards.

Users, uses and context
The data presented here are used by central government departments and local authorities for a range of purposes including planning and monitoring of services.

Rounding applied
Data are provided on an unrounded basis although the Office for National Statistics advises that any results presented from these data are rounded to the nearest 100 where practical.

Revisions information
The data presented here reflect changes made to population estimates from 2001 to 2010 in re-basing the data to be consistent with the results of the 2011 Census (see weblinks).

This data set consists of inflow and outflow for internal and international migration from 2012-13 onwards. This additional data replaces the international migration flow data set (POPU5022), because the ONS judged that the data is a more accurate source of long-term migration at a regional level.

Mid-2012 to mid-2016 subnational population estimates for England and Wales were revised on the 22 March 2018, following methodological improvements (see weblinks).
