How reliable are the figures for Census Tract 105?
Every figure for Census Tract 105 on this page has a coefficient of variation under 40%, the Census Bureau's threshold for a usable estimate.
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.
