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