How reliable are the figures for Florissant?
9 of the 57 figures for Florissant 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.

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.
