Old and comfortable, in the middle of the six-town set. Median household income is $75,774, above the county's $72,646, and the median home value is $348,500, just below it. Seminole is also the only one of the six towns that sits south of Largo, which is a real if modest argument for its inclusion.
The first thing to get right is that the name covers two places of very different size, and most published figures do not say which one they mean. The incorporated City of Seminole holds 19,396 people in 5.18 square miles. The Seminole mailing address — ZIP code tabulation areas 33772, 33776, 33777 and 33778 — holds 71,678. The city's own website publishes a third figure of roughly 100,000 for a "Greater Seminole" area, which appears to reuse the number it gives for the fire district. Every figure on this page states which geography it measures.
The construction-era mix comes out backwards from the story the rest of this site tells. Seminole city is newer than Pinellas County — 54.1% of units predate 1980 against the county's 58.8% — so a roofing pitch built on old Pinellas housing stock is weaker here, not stronger. It is the one expectation in the research that reversed on contact with the data, and it is recorded rather than smoothed over.
The structure mix is the consequential finding. 24.6% of the incorporated city's housing units sit in buildings of twenty or more, and another 13.0% are manufactured homes. Between them that is 37.6% of the stock which does not generate a household-level roof, pool cage, seawall, impact-window or paver decision: condominium associations and manufactured-home parks buy those once, at board level, on bid. The trades that survive that filter are the ones that follow the person rather than the parcel — hearing aids, estate planning, senior living — plus the recurring services a resident still buys individually.
