**Dataset population:** Persons aged 16 to 64 in households **Age** 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. **Approximated social grade** Social Grade is the socio-economic classification used by the Market Research and Marketing Industries, most often in the analysis of spending habits and consumer attitudes. Although it is not possible to allocate Social Grade precisely from information collected by the 2011 Census, the [Market Research Society](https://www.mrs.org.uk/) has developed a method for using Census information to provide a good approximation of Social Grade. **Sex** The classification of a person as either male or female.
