The quick read

Reading Janesville, WI beyond the headline numbers

Janesville sits inside Rock County, Wisconsin, at roughly 42.68°N, -89.02°W. Its population of 64,123 and $73,446 median household income are the two most quoted figures, but in isolation they hide the shape of the city. A median home value of $223,400 paired with median rent of $1,054 is the starting point for a price-to-income read that tells you how stretched a typical household is before any other cost of living factor is considered. The 9% poverty rate next to that income figure is the better signal, two cities with identical medians can have very different lived realities depending on the income distribution underneath.

Health and healthcare access are the next layer most residents and prospective movers actually care about. CDC PLACES indicators for Janesville show the highest-prevalence measure is obesity at 41.6%, followed by short sleep duration at 36.3%. In and around Janesville, CMS Hospital Compare tracks 2 hospitals with an average rating of 3.5/5 and 2 carrying emergency departments, the ER count is the more actionable figure if you are evaluating a move because it defines the effective trauma radius.

Areazine reconstructs these layers from U.S. Census ACS (place-level economics and demographics), CDC PLACES, and CMS Hospital Compare, each updated on its own cadence, and pairs them with live alerts from FEMA, NOAA, FDA, and CPSC scoped to the Janesville area. The comparison bars next to each metric anchor the number against a national reference, which is the fastest way to tell whether Janesville is an outlier on a given dimension before drilling into the raw value.
