The ONS LS contains data on 1 per cent of the population of England and Wales. It can be used for several types of analysis: for example, studies using registration event data such as outcomes or studies using linked census data. Information collected on people enumerated with LS sample members living in private households is available and allows analysis of household and family circumstances and change in those circumstances between censuses.
Examples of studies using linked census data are as follows: studies of social mobility have examined changing class position by age. Information on co-residents of LS sample members has been used to study inter-generational mobility.
It is now possible to compare class mobility from 1971 to 1991 with mobility from 1981 to 2001.The size of the LS makes it suitable for the study of ageing. Studies have used the information collected on the co-residents and family status of LS sample members to examine changes to household and family arrangements that come with age. Census forms ask about addresses one year ago.
The linked census data in the LS have been used to study ten-year migration patterns between censuses. Also, information on place of enumeration in 1939 has been used to study migration over longer periods. The addition of 2001 Census information to the LS has meant that individual-level ethnic identity changes and changes in limiting, long-term illness status between 1991 and 2001 could study for the first time. The addition of 2011 data in 2013 will enable further linked analysis and a first opportunity to compare linked responses on religion, and on family relationships.
Dr Nicola Shelton, the Director and PI, says “We are excited about the CeLSIUS service coming to UCL. We anticipate the increase in impact from working with academic and non-academic users and the inclusion of the 2011 Census data in 2013.”
