San Francisco, CA versus Irvine, CA is a real move, not a trivia matchup.

Typical rents sit near $3,604 a month in San Francisco and $3,236 in Irvine, and median household income lands at $136,689 versus $122,948.

San Francisco takes job market and weather, while Irvine takes affordability. The widest gap is typical weather, where San Francisco leads by 40% — 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.
