2/27 - Selection of sub-sample (1)

In the LS, information about household type including communal establishment (CE) is collected at each census. We therefore have to select individuals who are present at two consecutive censuses and aged 65 or more at the first. Here we will use the censuses of 1991 and 2001. A weakness of the LS is that some people leave the country unrecorded in emigration statistics, so some people will be missing from the second census and we will not know why, or what their period of risk (of entering a communal establishment) was.

If people entered a CE after 1991 but returned to a private household by 2001, their transition will not be counted, but their presence will to some extent be cancelled out by people who entered a CE after 1991, were resident there at the 2001 Census but returned to a private household thereafter.

A much more serious limitation is the exclusion of people who died (or emigrated) between the censuses, including most of those who died shortly after entering a CE. Nevertheless it should be possible to make an informative comparison between those who are in a CE at the 2001 Census and those who have remained in a private household.
