This dataset provides information on commuting patterns by local authority in Wales and flows between Wales and the rest of the UK.Data collection and calculation
ONS have reweighted the APS to take account of population data from the 2011 Census. Therefore, all estimates from quarter 4 of 2004 to quarter 3 of 2014 have been revised.The Annual Population Survey, which includes the WLLFS, is an annual sample survey of households living at private addresses in the UK. The annual survey uses results from those sampled for the main quarterly Labour Force Survey and since 2001 additional persons have been sampled on an annual basis to provide a more robust (boosted) annual dataset across the UK, with estimates subject to much lower sampling variability. For Wales, the data are now based on an enhanced sample (around 350 per cent larger) compared to earlier years.
The additional persons sampled in the APS are based on four waves, over four years of the survey. For the first wave, the response rate in Wales is around 60%, with around 75% of these remaining by the fourth wave. In total, approaching 20,000 households are sampled each year for the APS in Wales.
The APS relates to calendar years, whereas the WLLFS used the year ending in February. Therefore values for 2001 to 2003 relate to the years ending February 2002, February 2003 and February 2004. Subsequent values relate to calendar years.

2001 to 2017Users, uses and context
We believe the key users of commuting in Wales statistics are:Ministers and the Members Research Service in the National Assembly for Wales;
Other areas of the Welsh Government;
Welsh Local Authorities
Other government departments;
Students, academics and universities;
Individual citizens and private companies.
The statistics are used in a variety of ways. Some examples of the uses include: Advice to Ministers; Research and general background material;
To inform debate in the National Assembly for Wales and beyond.
Statistical quality
As the LFS/APS is a sample survey all estimates are subject to sampling variability. This is because thesample selected is one of only a very large number of possible samples that could have been drawn from
the population. Standard errors (SEs) are commonly used as indicators of the extent to which the
estimate based on a sample differs from the true population value. The larger the standard error, the less
precise the estimate is. Coefficients of variation (CV) give the standard error as a proportion of the
estimate itself.
