Base for table
This table includes every LS member enumerated at the 1971 Census who fulfils all these conditions:
A household member was considered to be the LS member's parent if he or she was coded 3 (father) or 4 (mother) at LSRELAT7. LSRELAT7 is a derived variable indicating relationship of an 'other household member' to the LS member, as far as it can be determined from the Census question on relationship of each household member to the Head of Household.
Construction of variables: First reported qualification in 1971
This variable is based on NQAL1Q7 and NGCE7 in the NM71 table.

Neither had to be answered by retired persons over 70. For NQAL1Q7, only the first qualification recorded for each person has been coded in the LS; it is therefore not possible to be certain that this was the highest qualification recorded for that person.
The variable was constructed as follows:
