The population of Taiwan is approximately 23.36 million as of April 2025.
Immigration of Han Chinese to the Penghu Islands started as early as the 13th century. The main island was inhabited by a diversity of Taiwanese indigenous peoples speaking Austronesian languages until Han settlement began in the early 17th century, around the time of the Ming–Qing transition, when workers were mainly imported from Minnan region to the colony of Dutch Formosa in the southwest of Taiwan. According to governmental statistics, in the early 21st century, 95% to 97% of Taiwan's population are Han Taiwanese, while about 2.3% are Taiwanese of Austronesian ethnicity. Half the population are followers of one or a mixture of 25 recognized religions.
