This report describes findings from literature and document reviews exploring how to define, measure, and support family economic well-being in ECHV. The findings can provide useful insights to policymakers, researchers, and ECHV practitioners, who can learn about potential avenues to support family economic well-being, and who might be interested in different sections based on their work: Researchers might be most interested in the discussion of factors related to family economic well-being in Chapter II and the measures identified in Chapter III. ECHV practitioners might be most interested in the broad definition of family economic well-being at the beginning of Chapter II and the potential applicability to ECHV of practices that support family economic well-being in Chapter IV, which could help guide ECHV programs to adopt the practices. Policymakers might be most interested in the findings overview and implications in Chapter V, which offers ideas for filling gaps in research and practice identified through the literature and document reviews. This can encourage progress toward incorporating strategies that address family economic well-being in ECHV. (author abstract)
