health_mortality_by_age_county_year

All-cause mortality by age band - the age-of-death distribution m(a), (see yaml).

tier aTier A - CDC WONDER actual death counts by age band (not modeled), over the complete PEP population grid.

years

1990 – 2024

cadence

Annual (CDC WONDER final mortality, ~1.5-year lag)

overview

3,142 counties x 35 years x 10 age bands = 1,099,768 rows (plus legacy CT/AK FIPS). WONDER all-cause deaths cover 1999-2024; earlier years carry PEP denominators. Suppressed (1-9-death) cells carry null deaths/rate.

usage

how to use this table

method

int_mortality_wonder filtered to cause_code all_cause; death_rate_per_100k = deaths/population x 100k; suppressed cells null; missing WONDER cells are true zeros.

do not use for

Cause-specific mortality (all-cause only); sub-county geography; ages as exact (10-year bands).
