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

Welsh speaking ability (3 categories)

Description: This classifies a person as being able to "Speak Welsh". They may have also ticked one or more of the following: * understand spoken Welsh * read Welsh * write Welsh

In results that classify people by Welsh language skills, a person may appear in more than one category depending on which combination of skills they have.

Comparability with 2011: Highly comparable
