Age by Main language used at home (Northern Ireland) 2011

Dataset population: Persons aged 3 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.

Main language

The language that is a person's first or preferred language.

This information helps central government, local authorities and the NHS to allocate resources and provide services for non-English speakers, for example English teaching and translation services. It is a better indicator than country of birth, which was previously used to forecast the additional cost of providing services to people whose first language is not English.

The data are also used to assess the impact of English or Welsh language ability on employment and other social inclusion indicators.

Information on the number of British Sign Language users helps with service planning and assists in developing policies to address the needs of the deaf community.

These statistics are used by public service providers to effectively target the delivery of their services, for example in the provision of translation and interpretation services, the availability of English language lessons, and the distribution of official information leaflets in alternative languages.
