Las Vegas may market itself as “Sin City,” but new 2026 data reveals it doesn’t even crack the top five when measuring where Americans actually live their most indulgent lifestyles.

A comprehensive study commissioned by PokerTubecities analyzed nightlife density, adult entertainment venues, single population rates, STI prevalence, and excessive drinking through a weighted index — offering one of the clearest looks at America’s true party capitals.

New York City claimed the top spot with a commanding composite “sin” score of 8.85/10. New York City overwhelmed competitors with 3,822 bars and 422 nightclubs (the highest totals nationwide) plus 79 adult stores. Nearly 46.8% of men and 44% of women are single, and the city logged a chlamydia rate of 558.4 cases per 100,000 residents.

Phoenix, Arizona, delivered one of the biggest surprises of the study, ranking second place nationally with a “sin” score of 8.77/10. Phoenix stands out with 925 bars and 122 nightclubs. Phoenix also features 46 adult stores, 11 casinos, and one of the higher excessive drinking rates in the top 10 at 18.81%.

Public health data paints an equally intense picture with Phoenix recording 552.5 chlamydia cases and 296.6 syphilis cases per 100,000 residents. With 44.65% of men and 37.52% of women single, Phoenix has earned its reputation as a major nightlife and entertainment hub.

Tucson, Arizona, ranked 15th on the list with a score of 7.96/10. It has 245 bars, 21 nightclubs, 7 casinos, and 46 adult stores. Tucson shares the same elevated state-level STI rates (552.5 chlamydia and 296.6 syphilis per 100K) and excessive drinking rate (18.81%), with 48.05% of men and 41.72% of women single.

Las Vegas fell to 7th place with a score of 8.48/10, despite leading the nation in casinos (292) and posting a strong number of strip clubs (17). Researchers noted that Vegas appears built more for tourism than resident-driven sin, with lower single-resident percentages (39.51% single men and 34.02% of single women) and more moderate excessive drinking rates (14.89%) compared to the top cities.
