Prospective analysis of census and event data
For example: studies of associations between employment status and mortality, between economic status and cancer registrations, or between socio-economic factors and fertility; and survival analysis of mortality by area deprivation.
Prospective analysis of successive census data
For example: analysis of patterns of retirement migration; studies of the effects of divorce and remarriage on housing tenure; or comparison of changes in education, employment and migration between different decades.
Prospective analysis of successive event data
For example: studies of changes in birth spacing or associations between fertility and cancer survival.
This is especially useful for studies of ethnic or geographical factors.
Countries such as France, Denmark, Finland and the USA have similar programmes to the LS.
