New Evidence on the Fertility Transition in Ireland 1880-1911.

The article focuses on the fertility transition in Ireland during 1880-1911. The decline in Irish marital fertility was neither uniform nor universal. Between 1881 and 1911, there were increases in Counties Galway, Mayo, Roscommon and Donegal, while the decline in several other counties was small. Cohort parity analysis (CPA), a fertility measure devised by researcher Paul David and his research associates, provides a means of inferring the extent and timing of birth control within marriage from distributions of married women by number of children born. A key aspect of CPA is the extent to which married couples resort to contraception in order to "space" births. Ireland has played an important part in the development of CPA, because David and his colleagues believe that the rural Irish of 1911 provide a suitable model, not only for urban Ireland in 1911 and the United States around the turn of the century, but also for Western Europe, Canada, Australia, and New Zealand, from the mid-nineteenth through the early twentieth centuries.
