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

Technical Note:
The Population Estimates Program data used here are revised to reflect updated input data and new Census Bureau population controls. Population estimates for previous years change with the release of each new 5-year Census estimate. Since the U.S. Census Bureau revises their post-2010 estimates each year, the data presented here may differ from previously published estimates.
