ACS 2020–2024 · Santa Clarita city, California · Incorporated city · GEOID 0669088. The survey estimates a population of 230,221 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Santa Clarita is 38.4 years, with a 90% margin of error of 0.7 years. There are 75,808 households (±1,300). Age and household distributions show how these totals are composed; they do not establish which neighborhood suits a particular person.

Every count and share is an estimate. “±” is a 90% margin of error (MOE); pp means percentage points. Derived shares use the category count divided by the named universe. Aggregated category MOEs and percentage MOEs are approximate. A margin larger than half its estimate is flagged as low precision. Blank source uncertainty is shown as unavailable, never zero.
