Mandarin is the official national language and is spoken by the vast majority of the population of Taiwan. It has been the primary language of instruction in schools since the Japanese were forced out in the 1940s. As in Hong Kong and Macau, Traditional Chinese is used in Taiwan.
Most Waishengren speak primarily Mandarin. The 70% of the population belonging to the Hoklo ethnic group speak Taiwanese (a variant of the Min Nan speech of Fujian province) as their mother tongue, in addition to Mandarin, and many others have some degree of understanding. The Hakka ethnic group (15% of the population) use the Hakka language. Although Mandarin is the language of instruction in schools and dominates television and radio, non-Mandarin languages or dialects have undergone a revival in public life in Taiwan, particularly since restrictions on their use were lifted in the 1990s.
Taiwan's indigenous languages, the Formosan languages, do not belong to the Chinese or Sino-Tibetan language family, but rather to the Austronesian language family. Their use among Taiwan's aboriginal minority groups has been in decline as usage of Mandarin has risen. Of the 14 extant languages, five are considered moribund.

The Constitution of the Republic of China protects people's freedom of religion and the practices of belief. There are approximately 18,718,600 religious followers in Taiwan as of 2005 (81.3% of total population) and 14–18% are non-religious. According to the 2005 census, of the 26 religions recognized by the ROC government, the five largest are: Buddhism (8,086,000 or 35.1%), Taoism (7,600,000 or 33%), I-Kuan Tao (810,000 or 3.5%), Protestantism (605,000 or 2.6%), and Roman Catholicism (298,000 or 1.3%). But according to the CIA World Factbook and other latest sources from US State Department or the Religious Affairs Section of the MOI, over 93% of Taiwanese are adherents of a combination of the polytheistic ancient Chinese religion, Buddhism, Confucianism, and Taoism; 4.5% are adherents of Christianity, which includes Protestants, Catholics, and other, non-denominational, Christian groups; and less than 2.5% are adherents of other religions, such as Islam. Taiwanese aborigines comprise a notable subgroup among professing Christians: "...over 64 percent identify as Christian... Church buildings are the most obvious markers of Aboriginal villages, distinguishing them from Taiwanese or Hakka villages."
