Age by Occupation by Proficiency in English by Sex (Middle Super Output Areas in England and Wales) 2011

Dataset population: Persons aged 16 and over


Age is derived from the date of birth question and is a person's age at their last birthday, at 27 March 2011. Dates of birth that imply an age over 115 are treated as invalid and the person's age is imputed. Infants less than one year old are classified as 0 years of age.


A person's occupation relates to their main job and is derived from either their job title or details of the activities involved in their job. This is used to assign responses to an occupation code based on the Standard Occupational Classification 2010 (SOC2010).

Proficiency in English

Proficiency in English language classifies people whose main language is not English (or not English or Welsh in Wales) according to their ability to speak English. A person is classified in one of the categories:

  • Can speak English very well
  • Can speak English well
  • Cannot speak English well
  • Cannot speak English

This question was handled slightly differently in the England and Wales censuses.

In the English census a tick box was used in Question 18, asking 'What is your main language?', giving the option of 'English' or 'Other'.

In the Welsh census, a tick box was used in Question 18, asking 'What is your main language?', giving the option of 'English or Welsh' or 'Other'.

Those who ticked 'Other' would be asked about their ability to speak English.

A consequence of this is that a person who reports their main language to be Welsh and completed the Welsh census, will not be asked about their ability to speak English. Whereas a person who indicates that their main language is Welsh and lives in England would be asked about 'their ability to speak English'.
