Base for table

This table includes all LS members enumerated at the 1991 Census, EXCEPT those who have never been traced in the NHS Central Register (because their death could not therefore be linked to their LS record).

Construction of variable: ethnic group in 1991

This table uses the variable ETHNIC9 in the table ME91 unaltered except that some values have been grouped:

Construction of variable: whether dead by the end of 2001

The variable DEYRBDE (year of death) in the table DETH was used to identify LS members who died from the beginning of 1991 to the end of 2001. Any LS members who did not have a death record with a year of death between 1991 and 2001 (inclusive) were assumed to be still alive at the end of 2001.
