Mortality data for U.S. residents come from the National Vital Statistics System. Estimates based on fewer than 10 observed deaths are not shown and shaded yellow on the map.

Underlying cause of death is based on the International Classification of Diseases, 10th Revision (ICD-10)

  • Heart disease (I00-I09, I11, I13, and I20–I51)
  • Cancer (C00–C97)
  • Unintentional injury (V01–X59 and Y85–Y86)
  • Chronic lower respiratory disease (J40–J47)
  • Stroke (I60–I69)

Locality (nonmetropolitan vs. metropolitan) is based on the Office of Management and Budget’s 2013 county-based classification scheme.

Benchmarks are based on the three States with the lowest age and cause-specific mortality rates. 

Potentially excess deaths for each State are calculated by subtracting deaths at the benchmark rates (expected deaths) from observed deaths.

Users can explore three benchmarks

  • 2010 Fixed is a fixed benchmark based on the best performing States in 2010
  • 2005 Fixed is a fixed benchmark based on the best performing States in 2005
  • Floating is based on the best performing States in each year so change from year to year

See MMWR Surveillance Summary 66(No. SS-1):1-8 for more detail about methods.
