Behavioral Risk Factor Surveillance System (BRFSS)


BRFSS is the largest, continuously conducted, telephone health survey in the world. It enables the Centers for Disease Control and Prevention (CDC), state and local health departments, and other health agencies to monitor the health and health behaviors of adults to guide policy and programs.


County Health Rankings & Roadmaps


The Rankings are produced every year by the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute. The Rankings measure the health of nearly all counties in the nation and rank them within states.

Office of the Superintendent of Public Instruction (OSPI)


OSPI provides aggregate school enrollment numbers, dropout and graduation rates for Washington schools, as well as aggregate demographic and testing data. 

United States Census Bureau


A complete census of all residents is conducted every 10 years in the United States. The last census was completed in 2020. The census has a limited number of questions about the demographics of our population.  In addition, the Census Bureau conducts the American Community Survey (ACS) every year.  The ACS is a mandatory, ongoing statistical survey that samples a small percentage of the population every year to gather information about population characteristics, housing, and economics among other topics. Due to the impact of the COVID-19 pandemic, the Census Bureau did not release 2020 ACS 1-year data products, but 5-year data products are available for all 5-year periods. For more information about the American Community Survey, see census.gov/programs-surveys/acs

Washington State Department of Health (DOH) Data and Statistical Reports


DOH makes data and statistical reports on health, healthcare and the environment available to the public.  Topics range from cancer and communicable diseases to drinking water and births and deaths, among others.  The Washington Tracking Network (WTN), a DOH data system, is an easily accessible source for environmental and public health data, including tables, charts and maps. 

Washington State Department of Social and Health Services (DSHS)


DSHS’s Facilities, Finance and Analytics Administration (FFA) provides leadership in financial, operational and risk management services.  This administration produces a comprehensive time-series collection of county and school district-level data related to substance use and abuse, and the risk factors that predict substance use among youth, called the Risk and Protection Profiles for Substance Abuse Prevention for Washington State and its Communities.  In addition, they provide aggregate client counts, use rates and cost by age groups for many DSHS services, as well as research articles on mental health and substance use in Washington. 

Washington State Healthy Youth Survey (HYS)


HYS is a collaborative effort of the Office of the Superintendent of Public Instruction, the Department of Health, the Department of Social and Health Services Division of Behavioral Health and Recovery, and the Liquor Control Board. HYS provides information about the self-reported health and health behaviors of youth in grades 6, 8, 10 and 12 in Washington to guide policy and programs that serve youth. 

Washington State Office of Financial Management (OFM)


OFM provides population estimates by age, sex, race and Hispanic origin, as well as estimates of population density and change. 

Washington State Statistical Analysis Center


The Washington State Statistical Analysis Center provides access to crime and justice statistics and conducts studies and analysis to inform Washington policy and budget development.  They maintain a clearinghouse for crime and justice statistics, with data on crime, arrests, court filings and sentences, jail and prison populations and juvenile justice.
