The National Center for Health Statistics has created a new data dashboard on drug overdose mortality in US counties: https://www.cdc.gov/nchs/data-visualization/drug-poisoning-mortality/
The dashboard includes several tools which will be use for those agencies working with substance use disorder issues. Through drop-down menus tables can be generated for mortality trends for each county and urban/rural trends for each state. Urban/rural definitions are based upon the NCHS 6-part classification system with separate identification of non-metro Micropolitan counties and non-metro Non-Core counties.
