Top cities (2 tracked)
Top drawbacks
- ✕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.
District of Columbia (DC)
Tax reality
DC has 10.75% top income tax (highest in the nation) PLUS you pay federal taxes — no local alternative. A $150K earner pays ~$30K in combined federal + DC income tax. The tradeoff: recession-proof federal job market, world-class walkability, and no need for a car (saving $600+/month).
Top cities (1 tracked)
Top drawbacks
- ✕Taxation is punishing — 10.75% local income tax combined with federal income tax means high earners pay 37-50% marginal rates. Capital gains tax applies at full income tax rate (not preferential), making real estate sales and investments expensive. This is the highest combined rate in the US.
- ✕No Congressional representation — DC has a Non-Voting Delegate but cannot pass laws without Congressional approval. Congress controls DC's budget. This is frustrating on principle and practically limits local autonomy.
- ✕Summer humidity is extreme — June-August average 90°F+ with 75%+ humidity, making heat index feel 100-108°F. Outdoor activity collapses. This is worse than the South because of the Potomac humidity.
