What to Expect in Kentucky
The honest trade-offs. People who move here usually don't regret it, but these are the things to plan for.
Kentucky ranks in the bottom half of US states on most health metrics — obesity, smoking, opioid use, chronic disease. Healthcare exists in the metros but public health is weaker than average.
Rural Kentucky has significant economic distress from coal industry decline and opioid crisis aftermath. This affects the state's political climate and services.
Louisville has real public safety concerns in specific west-end neighborhoods. Most of east Louisville, the Highlands, and the core downtown/NuLu areas are generally fine.
Public schools in Kentucky lag the US median outside of well-regarded suburban districts (Oldham County in Louisville, Fayette County in Lexington).
Summers are humid-subtropical — 90°F+ with humidity from June through early September.

Not legal advice. For complex situations (large capital gains, stock options, deferred comp), consult a tax CPA before moving.
