This data tool serves as a complement to a research project conducted by the Center for Migration Studies of New York (CMS),[1] entitled “Mapping Key Determinants of Immigrants’ Health in Brooklyn and Queens.”  The tool is intended to allow healthcare providers, government agencies, and non-profit immigrant-serving entities, including faith-based organizations, to identify and potentially meet gaps in services to immigrant populations, particularly healthcare, housing, legal, educational, work-related, and other services.  While the emphasis of the CMS study was Brooklyn and Queens, the data tool covers immigrant communities in the Bronx and Manhattan as well.
