Mad River, California: commercial real estate data.
Mad River is a Census CDP of 272 people across 35.19 square miles of land, in Trinity County. 86.0 percent of occupied homes are owned, and the SBA record carries 1 7(a) approvals to borrowers here worth $10,000 since FY2020.
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 Mad River through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 272 with a margin of error of plus or minus 202, which is 74.3 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.
Nothing has been removed or adjusted. These are the published federal estimates, shown with the uncertainty the Census publishes alongside them.
