Every figure comes from the Survey of Construction microdata, 2025 file, published by the U.S. Census Bureau. The survey follows a sample of new single-family houses from building permit to completion and sale, and HUD helps fund it. The file holds about 50 characteristics for each sampled house. Variable definitions are in the Census variable guide.
Which homes are counted
- Houses completed in 2025: 13,440 sampled homes, representing about 1,000,000 new homes.
- Price and homeowners association figures by price use homes completed and sold in 2025, because only homes built for sale have a sale price.
- Comparisons by size, lot or price leave out homes whose value Census altered for privacy. Census flags these, and it changes the top and bottom of each range.
How the figures are calculated
- Every share and median uses the survey weight, so it describes all new homes, not just the sampled ones.
- Build time is the number of months from the month construction started to the month the house was completed. Census's own published averages use a different method, so they won't match exactly.
- The file has no replicate weights, so OneFabHome doesn't publish margins of error or claim that small differences are significant.
Rules for publishing a number
- A group is shown only when at least 100 sampled homes sit behind it.
- Every comparison an article makes in words, such as one group being more than twice another, is checked against the data each time the site is built. If the data stops supporting it, the build fails.
- Built-for-sale and built-for-rent homes are never compared with each other, because the Census guide and the 2025 file describe that split differently.
