San Antonio, TX versus Arlington, TX is a real move, not a trivia matchup. This comparison uses the same 2026 neighborhood report data we publish on each city page — typical rent, median household income, crime indexes, school composites, and typical weather — so you can see which city actually fits how you live, work, and spend. Typical rents sit near $1,426 a month in San Antonio and $1,723 in Arlington, and median household income lands at $59,593 versus $71,736. Open either city's full report when you want the block-level detail behind these headlines.
San Antonio takes affordability and weather, while Arlington takes job market. The widest gap is median income, where Arlington leads by 20% — the kind of spread you feel in a monthly budget or a nightly walk, not just on a chart. Read the category rows as a filter: if cheaper housing would change your life more than a stronger job market, weight rent first. If you are moving with kids, weight schools and crime. If you picked a city after one good weekend, use the weather and income rows to test whether that weekend survives a full year.
