Jacksonville, FL versus St Petersburg, FL is a real move, not a trivia matchup.

Typical rents sit near $1,658 a month in Jacksonville and $1,977 in St Petersburg, and median household income lands at $64,138 versus $93,273. Open either city's full report when you want the block-level detail behind these headlines.
Jacksonville takes affordability, while St Petersburg takes job market and weather. The widest gap is median income, where St Petersburg leads by 45% — 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.
