How reliable are the figures for Census Tract 166.01?

1 of the 18 figures for Census Tract 166.01 on this page carries a coefficient of variation over 40% and is marked with a ring: they come from a small sample, so read them as rough.

A census tract's figures rest on a few hundred sampled households over five years, so its margins are wider than a city's. Two tracts differ only when the gap between them is larger than their combined 90% margin (the square root of the sum of the two squared margins). How to read a margin of error.
