Uniting the Kingdom with the States: The UK-US Census Linking Project, 1850-1920

with Gaia Dossi, 2022

Over the XIX and early XX century, approximately 4 million British immigrants settled in the United States. This project develops a new dataset which allows to link every migrant recorded in the US census to his entry in the UK census. To do so, we leverage individual confidential data from historical censuses recorded in both countries between 1850 and 1920 and state-of-the-art algorithms explicitly developed to link census data. We can thus reconstruct disaggregated bilateral migration flows between the UK and the US. The resulting dataset is a general-purpose novel tool available to social scientists which allows to study migration phenomena at an unrivalled level of detail.

A Nation of Emigrants: The Italian Mass Migration to the US, 1892-1924. Individual-Level Data from Ellis Island

with Lorenzo Spadavecchia, 2022

Between 1890 and 1924 more than four million Italians emigrated to the United States. During this period, Italy was the single largest supplier of emigrants in the world. This dataset tracks Italians who arrived in the Ellis Island immigration station between 1892 and 1924. We collect individual-level information on 3.6 million immigrants, including immigration year, literacy status, municipality of origin, and age. In ongoing work, we are leveraging census linking algorithms to merge the resulting dataset with individual-level historical (US) census data. This will yield a novel tool to study a broad set of questions concerning one of the defining immigrant group in (historical) American society.
