St. Clair, Pennsylvania: commercial real estate data.
St. Clair is a Census CDP of 37 people across 0.03 square miles of land, in Blair County. 100.0 percent of occupied homes are owned.
Underlined figures are computed by MMCG Analytics, not published by the agency.
This is a small place, and the figures below carry wide margins.
The American Community Survey reaches St. Clair through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 37 with a margin of error of plus or minus 40, which is 108.1 percent of the estimate itself. Every figure whose margin reaches 20 percent is printed with that margin beside it, so you can see the width of each one rather than having to assume it. Because the margin here exceeds the estimate, this page shows its strongest sections only rather than a full profile.
Nothing has been removed or adjusted. These are the published federal estimates, shown with the uncertainty the Census publishes alongside them.
