Data & Sources

Seattle is poised to be one of the first U.S. cities to create a safe consumption space (SCS), a proven and positive solution that reduce deaths and medical issues, restore public safety and community spaces, and connect people who use drugs with resources for treatment. But every day we delay means more deaths. For information about why SCSs are a proven, evidence-based model that can work, go to:

Data for Drug Use Deaths

The content below provides the methodology used for this site.

The King County Heroin and Prescription Opiate Addiction Task Force Report’s publish date of September 15th is on the first page of the report. You can read the report as a free pdf from the website.  They also have video and infographics about the report available.

The current number of deaths shown on the home page of is an estimate based on data from the previous year. In order to calculate an estimate we use the numbers published in the University of Washington Alchohol and Drug Abuse Institute report, “2016 Drug Use Trends in King County, Washington.

The calculation works like this:

332 deaths in the 365 days of 2016: 332/365 = 0.9095890411 deaths/day

The website determines how many days have passed since the recommendations were published and then multiplies that number by 0.9095890411 to estimate the number of deaths to date. That figure is then rounded down to a whole number.

Note:  Our estimate does not account for the fact that the number of drug-related deaths in King County has increased every year since 2011. The data for 2018 may end up being higher than our estimates.
