Using our interactive chartsOpioid use, morbidity, and mortality have increased nationally and across Washington State. To provide insights into how and where changes are occurring, we visualize several data sources on this site. Interventions, treatment, and the opioid overdose antidote naloxone, work equally well for all opioids. For more on opioid treatment and naloxone, go to stopoverdose.org.
Many of the charts on these pages are interactive. You can move your pointer over or click on a data point to see the count or rate, or on an item in the legend to highlight that data series. Click on a legend entry to turn that series on or off to better see the data.
Data on this page are presented as counts, while data in other pages (see menu or landing page) are usually in rates, estimated as per 100,000 residents in the county or state to control for changes in population. Note that Washington has several counties with small populations, which may make rates unstable: A small change in the numerator (an increase in the count of 3 or a decrease of 2, for example, in a population of 5000) could result in a relatively large change in the rate. Garfield, Wahkiakum, Columbia, and Ferry Counties each have well under 10,000 residents.
