While its population is predominantly of Chinese ethnicity, it is one of the most culturally and linguistically diverse provinces in China. The dialects of the language group Min Chinese were most commonly spoken within the province, including the Fuzhou dialect of northeastern Fujian and various Hokkien dialects of southeastern Fujian. Hakka Chinese is also spoken, by the Hakka people in Fujian. Min dialects, Hakka and Mandarin Chinese are mutually unintelligible. Due to emigration, a sizable amount of the ethnic Chinese populations of Taiwan, Singapore, Malaysia, Indonesia, and the Philippines speak Southern Min (or Hokkien).
With a population of 41.5 million, Fujian ranks 15th in population among Chinese provinces. In 2022, Fujian's GDP reached CNY¥5.31 trillion (US$ 790 billion by nominal GDP) 768 billion US dollars (CNY 790 billion), ranking 4th in East China region and 8th nationwide in GDP. Fujian's GDP per capita is above the national average, at ¥126,829 RMB (US$18,856 in nominal), the second highest GDP per capita of all Chinese provinces after Jiangsu. It has benefited from its geographical proximity with Taiwan. As a result of the Chinese Civil War, a small proportion of Historical Fujian is now within the Republic of China (ROC, Taiwan). The Fujian province of the ROC consists of three offshore archipelagos namely the Kinmen Islands, the Matsu Islands and the Wuqiu Islands.
