This is a small place, and the figures below carry wide margins.
The American Community Survey reaches Mermentau through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 627 with a margin of error of plus or minus 316, which is 50.4 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.
