FIGURE 2.

The figure shows age-adjusted rates for drug overdose deaths in the United States, by sex and residential area, using data from the National Vital Statistics System for 1999–2015. Death rates per 100,000 persons were adjusted to the 2000 U.S. standard population by the direct method. Data are shown for six classification levels for counties: 1) large central metropolitan: part of a metropolitan statistical area with ≥1 million population and covers a principal city; 2) large fringe metropolitan: part of a metropolitan statistical area with ≥1 million population but does not cover a principal city; 3) medium metropolitan: part of a metropolitan statistical area with ≥250,000 but <1 million population; 4) small metropolitan: part of a metropolitan statistical area with <250,000 population; 5) micropolitan (nonmetropolitan): part of a micropolitan statistical area (has an urban cluster of ≥10,000 but <50,000 population); and 6) non-core (nonmetropolitan): not part of a metropolitan or micropolitan statistical area.
