Big Arm, Montana: commercial real estate data.
Big Arm is a Census CDP of 190 people across 5.42 square miles of land, in Lake 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 Big Arm through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 190 with a margin of error of plus or minus 146, which is 76.8 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.
