Immigrant legislation, across and within the United States

Abstract

State governments are now the principal source of immigrant legislation in the US. Existing research presents contradictory findings concerning the sources of pro- and anti-immigration state legislation. However, research has not adequately accounted for the multidimensional nature of immigrant legislation and the fact that many variables hypothesized to affect state legislation encompass both within-state, time-varying effects and time-invariant, cross-sectional effects. Measurement and research design strategies to address these problems are applied to a dataset of state immigrant legislation approved between 2005 and 2012. The findings are important because they show that partisan, demographic, and economic effects are often different within versus across states and may differently affect the volume versus the relative tenor of legislative output.
