The majority of native Matsu Islands residents originated from Northern Fujian. Several of the islands of Matsu are not inhabited permanently. Some of these are garrisoned by soldiers from the Republic of China Armed Forces stationed in the county since the end of the Chinese Civil War in 1949 and during the First and Second Taiwan Strait Crisis in 1954 and 1958 respectively. Due to that high military demand large numbers of military personnel stationed on the islands produced unprecedented population growth in the county. The population reached its peak in 1971 with a total of 17,088 people. After those periods of high growth the population decreased year after year due to the poor economic growth which resulted in mass youth emigration due to lack of employment opportunities. In recent years the population in the county has gradually increased because of immigration. The population has stabilized due to the improved transportation between Taiwan Island and Matsu Islands as well as mass construction projects.
