The 1962 Family survey was the occasion for a major transformation. A separate two-page questionnaire is coupled with the census questionnaire.
The field was broadened to non-single women aged under 70. Single women were still excluded. Thus the 1962 questionnaire still express the hegemony of marriage.
The 1962 survey data was analyzed with delay and the first
findings were only published in the late 60’. For these reasons, no
Family survey was coupled with the 1968 census.
