05 — About this data

How percentiles are calculated

Percentiles compare this ZIP Code with other ZIP Codes in the same county, the same state and the whole country. Only ZIP Codes with their own American Community Survey estimate, a population of at least 1,000 and a published median household income are compared, and only those with a value for the measure. A percentile of 64th means the value is higher than 64% of the other ZIP Codes in that group (0 is the lowest value, 100 the highest); it describes the size of a number, not a judgment about the area. County and state percentiles are left blank when the group has fewer than 5 ZIP Codes. The number of ZIP Codes compared is shown with each percentile.

Census figures are published for ZIP Code Tabulation Areas, which approximate USPS ZIP Code delivery areas; values shown as — are not published or are suppressed by the source.
