schema
fields
| name | type | definition |
|---|---|---|
| _ingested_at | timestamp | Timestamp when this record was written to BigQuery.Pipeline metadata field. |
| _ingestor_version | string | Version of the ingestor script that produced this record.Pipeline metadata field. |
| _reliability_tier | string | Data quality tier (A/B/C) assigned at ingestion.Pipeline metadata field. |
| _source_dataset_id | string | Internal dataset identifier linking to meta.datasets.Pipeline metadata field. |
| cardiovascular_deaths | int64 · count | Total number of deaths attributable to cardiovascular disease in the county for the given year. Higher values indicate greater absolute cardiovascular mortality burden. |
| cardiovascular_deaths_per_100k | float64 · rate per 100k | Age-adjusted cardiovascular mortality rate, calculated as (cardiovascular_deaths / population) × 100,000. Higher values indicate greater cardiovascular mortality relative to population size. |
| ci_lower_95 | float64 · rate per 100k | Lower bound of the 95% confidence interval for the cardiovascular mortality rate per 100,000 residents. Values close to the point estimate indicate greater statistical precision. |
| ci_upper_95 | float64 · rate per 100k | Upper bound of the 95% confidence interval for the cardiovascular mortality rate per 100,000 residents. Wide intervals relative to the point estimate indicate greater uncertainty, often due to small county populations. |
| country_id | string | ISO alpha-2 country code (always 'US' for domestic tables). |
| county_idkey | string | 5-character FIPS code identifying the county.Joins dim.counties on county_id. |
| county_name | string | Human-readable county name corresponding to county_id. |
| population | int64 · count | Total resident population of the county for the given year, used as the denominator for rate calculations. |
| state_id | string | 2-character FIPS code identifying the state.Joins dim.states on state_id. |
| yearkey | int64 | Reference year of the observation. |

usage
how to use this table
method
Age-adjusted mortality rate for cardiovascular causes (ICD-10 I00-I99), aggregated by CHR from CDC WONDER multiple-cause mortality. <10 deaths suppressed.
do not use for
Single-year change in small counties (suppression and noise); sub-cause detail (cardio is broad - use specific ICD codes); cause-of-death at sub-county.
known issues
WONDER suppression of cells with <10 deaths.
