Illegal immigration and the crimes illegal immigrants commit are notoriously difficult to measure. This policy analysis is the latest paper in a series that attempts to answer that question by estimating illegal immigrant incarceration rates in the United States by using the American Community Survey Public Use Microdata Sample from the U.S. Census. This analysis goes beyond previous studies in the series as it updates our residual estimation method based on new research. Furthermore, we apply the updated methods to estimate the illegal immigrant incarceration rates in earlier years.
