Why This Indicator Matters

Young adulthood is a critical developmental stage during which markers such as educational attainment and employment impact future economic security, health, and overall well-being.1 Young adults are less likely to have health insurance and access to health care services compared to other age groups. Emerging adults who experience less financial hardship and do not engage in substance use and/or criminal behavior report better outcomes as they transition into adulthood.2
