This report was written in partnership between Cities for Action (C4A) and the Lumos Foundation. C4A is a coalition of over 175 U.S. mayors and county executives who advocate for pro-immigrant federal policies and create inclusive local programs and policies.

The material in this report was drawn from a range of sources. Background about the practice of family separation comes from material released by the federal government as well as legal filings. Information about local leaders’ advocacy was collected through open letters, press conferences, and public statements by local leaders. Interviews with officials in the localities profiled in this report and publicly available information from community organizations provided insights into local service provision to separated children and families. Guidance on the management of trauma to children, family reunification, and alternative care is derived from Lumos’ experience supporting vulnerable children and families across the globe. It is supported by internationally accepted best practice in the fields of social work and children’s rights.
