Caveats

• All values are single-year survey estimates and carry margins of error not stored here; small states and small differences between years can be within the margin of error.
• Dollar figures (economy.median_household_income, housing.median_home_value, housing.median_gross_rent) are in that survey year's dollars and are not adjusted for inflation across years.
• 1-year estimates are not comparable to 5-year estimates (see census-acs5) for the same geography or metric: different reference periods produce different figures even when nothing changed.
• There is no standard 2020 ACS 1-year release; the Census Bureau replaced it with experimental estimates because of COVID-19 data collection disruption, and 2020 is omitted here rather than substituted.
• 2010-2019 were pulled from the Census Data API (api.census.gov), which requires an API key; 2021-2024 were pulled from Census's keyless bulk table-based Summary File (www2.census.gov), which only exists in that convenient one-file-per-table layout from 2021 onward and was already on hand. For 2023 both sources were fetched and every value compared; they agreed exactly.
• economy.poverty_rate and economy.uninsured_rate are derived from detailed tables B17001 and B27001 rather than the Census subject tables S1701/S2701, because the subject tables' column numbering for these percentages has changed across vintages (confirmed: S2701's 'percent uninsured' column moves from C03 to C05 between 2014 and 2015, and the table does not exist before 2013), while the detailed-table variable numbers used here are stable back to at least 2010.
• All rate and share metrics (percent unit) are rounded to one decimal place by this puller; level metrics are stored exactly as published.
