Although the overall violent crime rate in Taiwan is low, you should avoid high crime areas, namely areas where massage parlors, barbershops, and nightclubs operate as covers for prostitution and are often run by criminals.
Taiwan’s public buses and subway are generally considered safe, but passengers in taxis – particularly women - should exercise caution when traveling alone in taxis late at night. In several parts of Taiwan, incidents of purse snatching by thieves on motorcycles have been reported.
Taiwan is a modern democracy with vibrant public participation. Political demonstrations are common, especially around election time. Since Taiwan democratized in the early 1990s, there have been very few cases of violence associated with political demonstrations. But even demonstrations intended to be peaceful can turn confrontational. You should avoid areas of demonstrations if possible and exercise caution if within the vicinity of any political demonstrations.
