Abstract
Summary: In this paper, non-marital pregnancies are defined as the sum of ex-nuptial confinements and the first nuptial confinements delivered within the first 8 months of marriage. Analysis is based on the annual statistics of live births, marriages and female non-married population as enumerated in the 1947–71 censuses. The incidence of non-marital pregnancies increased significantly in Australia between 1947 and 1971. This was found to be mainly due to rising ex-nuptial fertility rates, and, to a much lesser extent, to increased frequency of pre-marital pregnancies. A lesser proportion of pregnant non-married women were married before delivery in 1971 than in 1947. Some of the social implications are discussed.
