2010-2012 Mortality Rate Maps By U.S. Congressional Districts


Diseases of the heart, cancer, stroke, diabetes, chronic lower respiratory diseases (CLRD), Alzheimer's disease, and accidents (unintentional injuries) are among the leading causes of mortality in Tennessee. The following series of maps presents 2010-2012 age-adjusted mortality rates for these diseases for Tennessee residents by U.S. congressional districts. They include maps for the total population as well as by gender and by race groups.


Age-adjusted mortality rates were calculated from the 2010-2012 Death Statistical System provided by the Tennessee Department of Health, Office of Health Statistics. Data were for Tennessee residents with underlying cause of death recorded as diseases of the heart (ICD10 codes of I00-I09, I11, I13, I20-I51), cancer (C00-C97), stroke (I60-I69), CLRD (J40-J47), diabetes (E10-E14), Alzheimer's (G30), or unintentional injury (V01-X59, Y85-Y86). Because 2010-2012 population data estimates by congressional districts were unavailable, 2010 population data alone were used as the denominators to calculate mortality rates. Greater than 96% of resident addresses were successfully geocoded to determine congressional districts. Rates were age-adjusted to the 2000 U.S. standard population using the direct method. Population data for residents under 1 year of age were not available, so the first age classification included all residents less than 5 years of age. Race classifications of "white" and "African-American" refer to individuals regardless of Hispanic origin.


In some districts, mortality rates were based on relatively small numbers of deaths, especially for African-Americans. These results should be interpreted with caution.
