How many people live in Twain, and is it growing?
The 2020 Census counted 75 residents in Twain, a full count rather than a sample. The 2020-2024 American Community Survey, a sample, estimates 31 (±27). The survey estimate is less than half the 2020 count: in a place this small the survey reaches a few dozen households, and a few of them can move the estimate a long way.
The Census Bureau publishes yearly population estimates for incorporated places only; Twain is a census-designated place, so its figures come from the ACS and the 2020 Census.

How reliable are the figures for Twain?
37 of the 41 figures for Twain on this page carry a coefficient of variation over 40% and are marked with a ring: they come from a small sample, so read them as rough.
The American Community Survey samples about one household in eight over five years, so every figure is an estimate with a 90% margin of error (shown under each value). A ring marks an estimate whose coefficient of variation is over 40%. A change is called only when the gap between the two periods is larger than their combined 90% margin (the square root of the sum of the two squared margins), the Census Bureau's test.
