Census figures are for the ZIP Code Tabulation Area, the Census Bureau's approximation of the postal zip, which can differ at the edges. Each carries its margin of errorMargin of errorThe range, at 90 percent confidence, within which a survey figure's true value probably falls, so 1,000 ±100 likely means between 900 and 1,100.More in the glossary at 90 percent; a figure whose margin is wide is marked as a rough estimateA rough estimateA figure whose margin of error is more than about half the figure itself; a figure whose margin passes about two-thirds of it is not shown.More in the glossary, and one too uncertain to read is not shown. Comparisons are with the zip's own division and the metro, never with another zip.
