General description
This dataset provides population density estimates in persons per square kilometre for the local authorities in Wales for the period from 1991 onwards. The figures are derived by diving the mid year population estimates by the latest land area estimates in square kilometres, measured at the mean high water mark, and excluding areas of inland water as recommended by the Office for National Statistics. The supporting population and area estimates are included in the dataset.

Frequency of publication

Data reference periods
Data are produced and reported annually and relate to the 30 June of each year for 1991 onwards, although the land area data is unchanged throughout the dataset and taken to be the latest available standard area measurements.

Users, uses and context
The data presented here are used to understand the different levels of population density in each of the local authorities in Wales, and how this is changing over time.

Rounding applied
Data are provided on an unrounded basis although the Office for National Statistics advises that the population estimates data found in this datasets and presented separately 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).

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