National Survey for Wales

The National Survey for Wales is the Welsh Government’s major survey of the general population in Wales. It covers a wide range of topics affecting people and their local area.

The information collected is used to inform the development of policy and the delivery of public services for the Welsh Government. The survey involves a 45 minute face –to-face interview with a randomly selected adult aged 16 or over per household in Wales / CAPI.

An expanded version of the National Survey began in 2016. It covers similar topics to the 2012-15 National Survey as well as a selection of topics from four other surveys. These are the Welsh Health Survey, the Active Adults Survey, the Arts in Wales Survey and the Welsh Outdoor Recreation Survey, all of which came to an end in 2014 or 2015. Results from the new survey are published in June each year from 2017 onwards. Datasets are also available via the UK Data Service.


From 2016-17 onwards, the achieved sample size each year is roughly 12,000 individuals (14,500 in 2012-13, 2013-14 and 2014-15). With Consent to link rate of 64%, 66% and 65% a linkable sample of 28,387 cases for the three years can be obtained.
