To be economically secure, families need both income and assets. Regular income helps families pay for their daily living expenses. In contrast, families need assets to weather financial hardships and get ahead. Assets provide a safety net for coping with unanticipated expenses and emergencies that could otherwise cause significant financial hardship. Assets also help families build wealth and plan for the future by, for example, saving for retirement or investing in their children's education. Despite the importance of assets, many families live without any type of financial safety net. The lack of assets among low-income families is especially pronounced. This strategy brief aims to help practitioners, policymakers, and program developers understand how to expand asset-building opportunities for low-income families. Drawing from research and practice, it presents promising strategies and considerations for improving savings and investments among this population. It also lays out key areas for further work and investment to help guide decision makers in the public sector, business community, and foundation community as they seek to support activities that improve outcomes for low-income families and communities.
