Across the US, local leaders are grappling with the challenge of boosting upward mobility and narrowing racial and ethnic inequities in their communities. The Boosting Upward Mobility: Planning Guide for Local Action builds on a foundation of data and evidence to help local governments better understand impediments to upward mobility, bring people out of poverty, and create more equitable results in their communities. The guide presents a comprehensive planning process that takes the user from start to finish to assess their readiness for action, build a cross-sector team, gather and analyze data, conduct community and stakeholder engagement, and identify needed systems changes to create a mobility action plan. Informed by best practices drawn from communities that have participated in our Upward Mobility cohort and from research on systems change and evidence-based decisionmaking, this guide presents real-world examples, worksheets, talking points, and checklists to help leaders track their advancement along the planning process.
