About this dataset

This dataset provides Census 2021 estimates that classify usual residents aged 16 years and over in Wales by ability to speak Welsh and by NS-SEC. The estimates are as at Census Day, 21 March 2021.

Protecting personal data

Sometimes we need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, we:

  • Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, we swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority.
  • Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when we applied perturbation.

About the variables

National Statistics Socio-economic Classification (NS-SEC) (10 categories)

Description: The National Statistics Socio-economic Classification (NS-SEC) indicates a person's socio-economic position based on their occupation and other job characteristics.

It is an Office for National Statistics standard classification. NS-SEC categories are assigned based on a person's occupation, whether employed, self-employed, or supervising other employees.

Full-time students are recorded in the "full-time students" category regardless of whether they are economically active.

Quality information: As Census 2021 was during a unique period of rapid change, take care when using this data for planning purposes.

Comparability with 2011: Not comparable. This variable is derived from the occupation variable. It cannot be compared with the one from the 2011 Census because the classifications in the occupation variable have changed
