The report leading to the creation of the SSRC in 1923 outlined several major challenges for social science: data collection, interpretation, measurement, and causality. This lecture will explore the extent to which newly available administrative datasets — linked together to create what is sometimes referred to as “big data” — can help address these challenges and contribute to our understanding of the causes and consequences of eviction and poverty in the United States. The lecture will draw heavily on a study of eviction in Chicago and New York, which is joint work with Robert Collinson, John Eric Humphries, Nick Mader, Davin Reed and Daniel Tannenbaum.
