Write to [email protected]. Reports of figures that do not match their source are the most useful thing a reader can send.
Report an error
Please include the page address, the figure you think is wrong, and the value you expected with its source: ideally the table and release it comes from. Every figure on this site has a numbered source note at the bottom of its page, so the quickest check is to open the same table for the same year. Differences of a dollar or a tenth of a point are usually rounding.
We check every report against the original release. Corrections are made as soon as they are confirmed and listed with the date on the updates page.
Questions about the data
We can explain how a measure is defined, which table it comes from and why two sources disagree. The methodology answers the most common questions, including how ranks and significance are set and why a state has several official population figures.
What we cannot help with
We publish state-level statistics only. We cannot supply figures that the agencies do not publish, such as data for individual addresses, or give legal, financial or relocation advice.
