    The Problem of False Positives in Automated Census Linking: Evidence from Nineteenth-Century New York's Irish Immigrants
    (University College Dublin. School of Economics, 2021-06) ; ; ;
    Automated census linkage algorithms have become popular for generating longitudinal data on social mobility, especially for immigrants and their children. But what if these algorithms are particularly bad at tracking immigrants? Using nineteenth-century Irish immigrants as a test case, we examine the most popular of these algorithms—that created by Abramitzky, Boustan, Eriksson (ABE), and their collaborators. Our findings raise serious questions about the quality of automated census links. False positives range from about one-third to one-half of all links depending on the ABE variant used. These bad links lead to sizeable estimation errors when measuring Irish immigrant social mobility.

    Immigrants and Savers: A Rich New Database on the Irish in 1850s New York
    (University College Dublin. School of Economics, 2017-04) ; ;
    We describe a new dataset created from the first 18,000 savings accounts opened (from 1850 to 1858) at the Emigrant Industrial Savings Bank in New York City. The bank was founded by Irish Americans and most of its depositors in its first decade of operations were recent Irish immigrants. The data offer a unique window on both savings behavior by the poor and not-so-poor in antebellum New York and on how emigrants who came primarily from rural parts of Ireland adapted to urban life. They also contain much that is new on the regional origins of mid-nineteenth century Irish immigrants and on their settlement patterns in New York.
