schema
fields
| name | type | definition |
|---|---|---|
| cancer_avg_annual_deaths | float64 · count | Average number of cancer deaths per year in the county, typically calculated as a multi-year average to smooth small-county volatility. Higher values reflect greater absolute cancer mortality volume in the county. |
| cancer_mortality_per_100k | float64 · rate per 100k | Age-adjusted cancer mortality rate expressed as deaths per 100,000 persons per year, based on a standard reference population. Higher values indicate greater cancer mortality burden in the county. |
| country_id | string | ISO alpha-2 country code (always 'US' for domestic tables). |
