米国連邦捜査局（FBI）の犯罪統計によると、2024年中、米国における凶悪犯罪（殺人、強制性交、強盗、加重暴行）の発生は1,221,345件、財産犯罪（侵入窃盗、窃盗、自動車盗）の発生は推計5,986,400件となっています。

ただし、例えば2024年の殺人事件発生総数は日本が970件であるのに対し米国は16,935件、強盗事件は日本が1,370件であるのに対し米国は205,952件であり、日米の人口差を考慮しても米国における犯罪発生率は日本よりも格段に高いことが分かります。また、米国ではこのような凶悪犯罪に銃器が用いられることが多い点にも留意する必要があります。

主要都市の空港や駅において、正規のタクシー乗り場や配車アプリの指定場所以外で、「タクシー?」などと声をかけてくる無許可営業の車（いわゆる白タク）による被害が報告されています。法外な料金を請求されたり、強盗被害に発展するリスクもあります。
