Regional variations in family size in the Republic of Ireland

Abstract

SummaryDate from the Census Fertility Reports are used to investigate social and regional variations in family size in the Republic of Ireland. Although Ireland is noted for its high level of fertility, average family size declined by approximately 10% between 1946 and 1971. There are distinct socioeconomic variations in family size in that Roman Catholic family size is greater than that of non-Catholics and the middle classes have the smallest families within each of the religious groups. There are also marked regional differences in family size. In 1946, there was a clear division between the west coast counties with the largest families and the east coast conties with the smaller families. By 1961 and 1971 this pattern had become less clearly demarcated and areas with relatively large families were found in most parts of the country. It is suggested that regional variations in family size can be influenced by a variety of factors, such as differences in religious affiliation, occupation, infant mortality and the degree of selection through emigration. Of these factors, it is found that in both 1946 and 1971 variations in occupation were most strongly related to family size and it appears that economic and occupation changes within Ireland have brought about the changing regional pattern of family size.
