Editorial & Corrections Policy
PlainPropertyTax turns the U.S. Census Bureau's published property-tax estimates into county, state, and ranking pages. This page explains how those pages are produced, the standards we hold them to, and exactly how to flag a number that looks wrong.
How Pages Are Produced
PlainPropertyTax's county and state pages are generated from a single documented dataset: the U.S. Census Bureau's American Community Survey (ACS) 5-Year Estimates. We download each year's published estimates directly from the Census Bureau's ACS program (tables B25077, B25103, B19013, and B25091), load them into a structured database, and render each geographic page from that database. The figures you see — median real-estate taxes paid, median home value, effective tax rate, and tax-to-income ratio — are computed from the Census Bureau's numbers, not hand-typed and not estimated by us.
This is a data-publishing model: the same template renders thousands of pages so that every one of the 3,152 U.S. counties is covered consistently. We are transparent that these data pages are produced programmatically from the source dataset rather than written individually. The editorial work goes into the pipeline (how data is sourced, normalized, and computed), the methodology, and the written guides — not into hand-authoring 3,100 near-identical county pages, which would add no accuracy and invite inconsistency.
Sourcing Standards
- Primary sources only. Property-tax figures come from the Census Bureau's published ACS 5-Year Estimates. Income context uses ACS median household income; where a deflator is applied it is the BLS Consumer Price Index, as documented in our methodology.
- Attribution in context. Each data page names its dataset and vintage near the figures, and links to the methodology that explains how the effective rate and burden ratios are derived.
- Derived values are labeled. Numbers we compute ourselves — effective tax rates, national percentile rankings, and tax-to-income ratios — are presented as our analysis of Census data, distinct from the Census Bureau's published figures.
- No invented data. Where a value is unavailable or has too small a sample for an area, the page says so rather than filling the gap with an estimate.
Update Cadence
The Census Bureau releases new ACS 5-Year Estimates once a year, in the fall. We refresh our database when each new release is published, adding the latest year while preserving prior vintages for trend comparison, and recompute year-over-year changes. Between annual releases the figures are stable because the source itself does not change; the five-year rolling window gives reliable estimates for small counties but can lag rapid changes in home values or local tax policy. The reference year is shown on every data page.
Corrections Process
If a figure on PlainPropertyTax looks wrong, please tell us. Because our pages are generated from the ACS dataset, a genuine error almost always traces back to either the source data or our processing of it — so this is how we handle a report:
- Report. Email us through the contact page with the page URL and the number that looks off.
- Verify. We compare the figure against the Census Bureau's published ACS tables for that area and year.
- Fix at the source. If the value is wrong on our side, we correct it in the database and pipeline that generate the page — not just on the single page — so every affected page is fixed at once. If the figure faithfully reflects the Census data, we explain that and, where useful, add context.
- Note it. Material corrections that change a published figure are reflected the next time the page rebuilds, with the data reference year shown so you can see which release a page is based on.
We aim to acknowledge data-error reports within a few business days.
Editorial Independence
PlainPropertyTax is an independent publisher and is not affiliated with the Census Bureau or any government agency. Our guides and analysis are not influenced by advertisers; advertising, where present, is clearly distinguishable from editorial content and never determines which counties or rankings we show. Our rankings are computed mechanically from Census figures, so no county or assessor can pay to move up — or down — a list.
Appropriate Use
PlainPropertyTax is for informational purposes only and does not constitute tax, financial, or legal advice. ACS effective tax rates are survey-based estimates for a whole county — a useful benchmark for comparison, not a quote for any specific parcel, and not your actual assessed bill. For decisions about an appeal, a purchase, or your budget, confirm current figures with your county assessor and consult a qualified tax or financial professional. See our disclaimer for details.
