The fertility of the Irish in the United States in 1910

The relatively high marital fertility of the Irish in the United States in the 19th century has long been interpreted as evidence for the persistence of a distinctive Irish culture in the United States. This claim echoes a similar view of Irish-American marriage patterns. Recent work has shown that the marriage patterns of the Irish in the United States were similar to native-born whites with similar occupational and other characteristics. This paper studies the reasons for the high fertility of Irish-Americans in 1910. Irish-born women in that year had much larger families than the typical native-born woman, and little of the difference can be attributed to other characteristics. Second-generation Irishwomen were less distinctive in this regard, although even they differed from the natives primarily because of a different proclivity to have a large family. Our results signal the complexity of immigrant adjustment to a new environment; the Irish largely abandoned one aspect of Irish demographic behavior while clinging to another. (c) 2005 Elsevier Inc.
