ZIP 51109

What ZIP 51109 actually tells you, and what it doesn't

The 51109 ZIP Code Tabulation Area has a population of 3,619 and a median household income of $73,158. Against the other tabulation areas in this dataset, it places as follows.

Housing is cheap here relative to local earnings. A home at the median costs about 1.7 years of a median household's gross income, which puts 51109 in the least expensive quarter of the 29,491 tabulation areas that report both figures. Areas in this range are usually either far from a major job centre or carrying housing stock that local wages have caught up with.

At the median, rent consumes roughly 16% of a median household's income -- below the midpoint for reporting areas, and well under the 30% line commonly used to define a cost burden.

The median age of 43.5 sits above the midpoint of reporting areas, the pattern of a settled population where more residents are past child-rearing than entering it.

ZCTAs approximate USPS ZIP codes rather than matching them, and these are 5-year ACS estimates, so they trail current conditions.
