Dementia Mortality in the United States, 2000-2017

Abstract

Objectives-This report presents data on mortality attributable to dementia. Data for dementia as an underlying cause of death from 2000 through 2017 are shown by selected characteristics such as age, sex, race and Hispanic origin, and state of residence. Trends in dementia deaths overall and by specific cause are presented. The reporting of dementia as a contributing cause of death is also described. Methods-Data in this report are based on information from all death certificates filed in the 50 states and the District of Columbia. Using multiple cause-of-death data files, dementia is considered to include deaths attributed to unspecified dementia; Alzheimer disease; vascular dementia; and other degenerative diseases of nervous system, not elsewhere classified. Results-In 2017, a total of 261,914 deaths attributable to dementia as an underlying cause of death were reported in the United States. Forty-six percent of these deaths were due to Alzheimer disease. In 2017, the age-adjusted death rate for dementia as an underlying cause of death was 66.7 deaths per 100,000 U.S. standard population. Age-adjusted death rates were higher for females (72.7) than for males (56.4). Death rates increased with age from 56.9 deaths per 100,000 among people aged 65-74 to 2,707.3 deaths per 100,000 among people aged 85 and over. Age-adjusted death rates were higher among the non-Hispanic white population (70.8) compared with the non-Hispanic black population (65.0) and the Hispanic population (46.0). Age-adjusted death rates for dementia varied by state and urbanization category. Overall, age-adjusted death rates for dementia increased from 2000 to 2017. Rates were steady from 2013 through 2016, and increased from 2016 to 2017. Patterns of reporting the individual dementia causes varied across states and across time.
