Immigration policymaking has been active at the local level in the United States over the past few decades. This study examines whether the economic development-oriented immigrant-welcoming efforts that started in 2010 in Detroit have increased the local immigrant population. It uses the synthetic control method to construct a comparison region that resembles Detroit in the preintervention periods to serve as a counterfactual. Empirical results reveal a statistically significant increase in the immigrant share of the population in the metropolitan area during the postintervention period of 2011–2014. The increase is robust to various sets of specifications and placebo tests. The share of high-skilled immigrants in the local population also increased during this time, albeit with a weak statistical significance. These findings point to the potential of immigrant-welcoming programs in attracting and retaining immigrants and immigrant talent.
