Direct variable: Question 3
May 10, 1901 to May 9, 2011
In 1966 and 1961, respondents were asked to state their age in completed years as of their last birthday before the census date. In 1961, published data for single years of age were graduated (or smoothed) within each five-year age group to counteract the tendency towards 'heaping' at certain specific ages. In 1966, this was not done, and the published tables represent the date as reported.
In 1991, 1986 and 1981, the day and month of birth were not retained for dissemination.
