Note: The manner in which underlying cause of death is coded and classified was revised in 1999 to reflect changing medical opinion and practice. The comparability between classification schemes for this particular cause of death is lower (1.55), meaning that caution should be taken in drawing specific inferences from comparisons of mortality statistics over time.

Notes:

The underlying cause of death is the condition giving rise to the chain of events leading to death. Between January 1, 1979 and December 31, 1998, the underlying causes of death were classified in accordance with the Ninth Revision of the International Classification of Diseases (ICD-9), a coding structure developed by the World Health Organization. Starting January 1, 1999, causes of death were classified using the Tenth Revision of the International Classification of Diseases (ICD-10). With each revision there are differences in classifying the underlying cause of death. Therefore, health statistics based on one revision are not directly comparable to the other revision without the use of comparability ratios.

(See "Comparability of cause of death between ICD-9 and ICD-10: Preliminary estimates." National vital statistics reports; vol 49 no. 2. Hyattsville, Maryland: National Center for Health Statistics. 2001. )
Alzheimer's Disease Deaths: Before 1999, deaths were classified with ICD-9 codes 331. Starting in 1999, deaths were classified using ICD-10 codes G30-G30.9.

Alzheimer's Disease Death Rates: Rates are per 100,000. Computed by the direct method, using as the standard population the age distribution of the total population of the United States for the year 2000. The true rate lies between the lower and upper bounds of the interval with 95% statistical confidence. If the confidence interval is large for a single year comparison, it is suggested that you use the three year and five year moving average rates.
