Summary of request
This analysis investigates the outcomes of those who were present, employed, and in the armed forces in England and Wales in the 1971 Census. This is done by looking at the outcomes for these individuals at each Census if they were still present. Essentially we look at four pairs of outcomes: 1971 to 1981, 1971 to 1991, 1971 to 2001 and 1971 to 2011. Those who are present in 2011 may not have been present at all census points.
The Longitudinal Study (LS) contains linked census and life events data for a 1% sample of the population of England and Wales (E&W). Life event data comes from the civil registration system, NHS registration systems and the cancer registries and includes data on: births, immigration, deaths and emigration data. The LS contains records on over 500,000 people usually resident in E&W at each point in time and it is largely representative of the population as a whole. The LS is the largest longitudinal data source in E&W.
The LS has linked records at each census since the 1971 Census, for people born on 1 of 4 selected dates in a calendar year. These 4 dates were used to update the sample at the 1981, 1991, 2001 and 2011 Censuses. New LS members enter the study through birth and immigration.
