Public Health - Seattle & King County

Mariko Toyoji, Epidemiologist

Communities Count is a resource that supports King County communities in the use of data in promoting and achieving equity. Communities Count does this by:

  • Providing a platform for community data & stories
  • Highlighting data on disparities, inequities and strengths in our community
  • Complementing existing civic, social, economic, and health indicators
  • Providing data support and trainings to King County communities


In its data reports on population and community indicators, Communities Count emphasizes prevention and a long-term view of change while using data to understand how to advance equity work to sustain healthy communities and families. The team also provides data support and data trainings for community-based organizations in King County on finding, interpreting, and using population health data.

Communities Count is staffed by members of Public Health – Seattle & King County’s Assessment, Policy Development, and Evaluation Unit. The Assessment, Policy Development and Evaluation Unit's primary work is assessment and evaluation of population-based data and interventions, integrating qualitative analysis, and policy development. The APDE unit is a multidisciplinary group of epidemiologists, social research scientists, and policy specialists. The group collaborates with community and other Public Health — Seattle & King County divisions, using and developing state-of-the-art techniques for data collection and analysis. Its goal is to provide leadership and technical assistance for population-level health assessment, data-driven program planning, program evaluation, and policy.
