U.S. Age-Adjusted Death Rates for Major Causes (1900-Present)

Age-adjusted death rates for selected major causes of death in the United States, spanning from 1900 to the present. The dataset tracks mortality trends, with rates calculated per 100,000 population using the 2000 U.S. standard population after 1998.

Use Cases

• Analyze long-term mortality trends for major causes of death across over a century of U.S. history.
• Compare age-adjusted death rate patterns before and after key revisions to the International Classification of Diseases (ICD).
• Study the impact of population estimate methodologies (e.g., postcensal, intercensal) on calculated death rates from 2000 onward.

Strengths

• Provides over 120 years of continuous mortality trend data from 1900 to the present.
• Uses standardized age-adjusted rates (deaths per 100,000) based on the 2000 U.S. standard population for consistent comparison.
• Compiled from authoritative CDC/NCHS sources including the National Vital Statistics System and CDC WONDER.

Limitations

• Revisions to the International Classification of Diseases (ICD) over time may create discontinuities in cause-of-death trends.
• Specific sample sizes, row counts, and column details are not provided in the input metadata.
• Death rates for noncensus years between 2000 and 2010 have been revised, which may cause discrepancies with previously published figures.
