Reinvestment Fund’s Limited Supermarket Access (LSA) analysis is a tool to identify areas across the 50 United States and the District of Columbia that have both inadequate and inequitable access to healthy food and sufficient market demand for new or expanded food retail operations. Using the LSA data on PolicyMap, a diverse range of clients—including policymakers, government agencies, lending institutions, community organizations, and researchers—can investigate LSA Areas within their geographies of interest and craft strategies based on the conditions specific to those communities.
