Struggling to make ends meet jeopardizes the health of more than 50,000 San Mateo County residents living below the federal poverty level. Studies of interventions like cash transfer programs and Earned Income Tax Credits show that boosting income for low wage workers improves public health outcomes. In California, policymakers are exploring expansion of the statewide EITC and local income guarantees as ways to ensure every resident has what they need to be healthy.
