As the demand increases for statistics and data to measure the impact of the COVID-19 pandemic, we have had to change our data gathering and release practices, focussing efforts on priority analysis and statistics.

YearAnnual Population Survey (APS) responses are weighted to official population projections. As the current population projections are 2018-based they are based on demographic trends that pre-date the COVID-19 pandemic. This will particularly affect estimates for country of birth, nationality, ethnicity and disability. See Metadata for more information.[Filtered]

General description

This dataset provides information on national identity by Welsh local authority.

Data collection and calculation

These data are taken from the ANNUAL datasets from the Annual Population Survey (APS) for 2005 onwards and the Welsh Local Labour Force Survey (WLLFS) prior to that. These surveys are carried out by the Office for National Statistics (ONS). The data for Wales are based on an enhanced sample (around 350 per cent larger) compared to earlier years. APS data are collected throughout the year and are published for calendar years. WLLFS data was published for the year ended February, each year i.e. 2001 WLLFS data relates to year ended February 2002. The data do NOT exactly match annual averages derived from the 4 QUARTERLY datasets in each year due to differences in the sampling structure.

The survey asks respondents what they consider to be their national identity. This table combines the non-Welsh groups together in order to increase the reliability of the estimates. Non-Welsh includes: English, Scottish, Irish, British and Other.
The local authority and Wales figures for 2001, 2002 and 2003 in these tables may not be the same as published elsewhere, as the numbers here are estimated using Welsh specific weights. These weights better reflect the population estimates for Welsh local authorities in these years.

Nomis is the ONS's official portal for labour market statistics. Note that some estimates from Nomis for the APS may differ slightly from those presented here due to differences in how local authority geographies are constructed.

Rounding applied

Figures are rounded to the nearest 100 and so there may be some apparent slight discrepancies between the sum of constituent items and the totals as shown.

Revisions information

In March 2019, the Annual Population survey data has been revised back to 2012, due to taking on board the latest population estimates.

September 2019: The percentage of people who consider themselves Welsh was previously calculated as a percentage of all persons - this has now been revised so that it is based only on those who responded to the question. The data for all previous waves have been revised. Revised data is marked with an (r).

Statistical quality

As the data come from a survey, the results are sample-based estimates and therefore subject to differing degrees of sampling variability, i.e. the true value for any measure lies in a differing range about the estimated value. This range or sampling variability increases as the detail in the data increases, for example local authority data are subject to higher variability than regional data.

These annual results refer to the period March to February each year. However, as the results from the quarterly surveys are combined with, results from additional persons sampled, they provide a more robust (boosted) dataset, with estimates subject to much lower sampling variability than the quarterly LFS.

Annual Population Survey (APS) responses are weighted to official population projections. As the current projections are 2018-based they are based on demographic trends that pre-date the COVID-19 pandemic. ONS are analysing the population totals used in the weighting process and intend to make adjustments where appropriate. Rates published from the APS remain robust; however, levels and changes in levels should be used with caution. This will particularly affect estimates for country of birth, nationality, ethnicity and disability.
Note: Data for 2011 Q1-3 removed due to change in questions resulting in discontinuity in the series.
