General description

This dataset provides information on the ethnicity of people 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).

Frequency of publication

Quarterly

Data reference periods

2001 to 2016

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

Note - 30 June 2016 - ONS have reweighted the APS to take account the latest population data. Therefore, all estimates from quarter 4 of 2012 to quarter 4 2015 have been revised.

Statistical quality

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 ethnic origin. This table combines the non-white groups together in order to increase the reliability of the estimates. Non-white includes: mixed, Asian or Asian British, Black or Black British, Chinese and other ethnic group. 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. 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.
