The quick read

Reading San Marcos, TX beyond the headline numbers

San Marcos sits inside Hays County, Texas, at roughly 29.88°N, -97.94°W. Its population of 268,638 and median household income of $89,097 are the two most quoted figures, but in isolation they hide the shape of the city. A median home value of $399,800 paired with median rent of $1,495 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 12.1% 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 San Marcos show the highest-prevalence measure is short sleep duration at 35.1%, followed by obesity at 34.5%. Within the city boundary, CMS Hospital Compare tracks 4 hospitals with an average rating of 4.5/5 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 geography), 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 San Marcos area. The comparison bars next to each metric anchor the number against a national reference, which is the fastest way to tell whether San Marcos is an outlier on a given dimension before drilling into the raw value.
