The Center for Migration Studies of New York (CMS) publishes estimates on the size and characteristics of the US undocumented and naturalization-eligible populations at national, state, and sub-state levels.
At data.cmsny.org, users can conduct their own queries of these populations. Based on its estimates, CMS has also published numerous reports and articles on immigrants potentially eligible for legalization under pending bills, how to expand access to naturalization, immigrant essential workers during the COVID-19 pandemic, and other issues of concern to policymakers.
In addition to its extensive, publicly-available data offerings, CMS also strives to answer individual queries that serve the public good. For example, CMS has produced data summaries and estimates for community-based organizations seeking to better understand the populations they serve, assisted researchers in their projects, and journalists reporting on their communities. If you have a data request that goes beyond CMS’s published estimates, we encourage you to reach out to us via the form below.
