Information is organized into four areas:

  • Prenatal to 5 years: Babies are born healthy and are provided with a strong foundation for lifelong health and well-being.
  • 5 to 24 years: King County is a place where everyone has equitable opportunities to be safe and healthy as they progress through childhood, building academic and life skills to be thriving members of their communities.
  • Youth and family homelessness prevention
  • Communities of Opportunity

To ensure that Best Starts for Kids funded activities contribute to desired population-level changes, Best Starts requests for proposals will ask organizations to be responsive to these indicators. Additional data resources and general population demographic data are available at Communities Count.
