How reliable are the figures for Census Tract 4515.06?
2 of the 18 figures for Census Tract 4515.06 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.

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.
