Each of these is absent for a reason, not by oversight. The Area Score is calculated without them; the weighting is on the methodology page.

Reported crime

Offenses reported to police are published by department rather than by town, so AreaProfile shows a rate only on city profiles, and only where that city’s department submitted every month of a year. A ZIP area is not a jurisdiction, so no department reports for one. San Marcos carries the figure where its department reported a full year. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.

Air quality

The EPA publishes an air-quality index only where a monitor sits. There is none in this county, and a modeled value would be a different kind of number from the measured ones everywhere else on this page.

Taxes

Income and sales taxes are not published: no source covers them nationally with a method open enough to check. Property taxes are shown in the housing section but are not part of the score. The cost-of-living index above is a price level for all consumption, not a household budget, and it excludes taxes. Nothing here is individualized tax advice.

Anything about a specific address

Every figure describes an area, not a street or a house.

Profile recalculated October 8, 2026. Recalculation is not the same as new source data — each figure above shows the period its source actually covers. Read the full methodology, or every source with how often each updates.

How this ZIP area compares with San Marcos as a whole. Both figures come from the same ACS release, so the comparison is like for like — a gap here is a real difference between the two places, not two surveys disagreeing.

Some demographic statistics use Census ZIP Code Tabulation Areas, which approximate but do not exactly match USPS ZIP delivery geography. See the methodology for how AreaProfile maps between them.
