By March 2015, the district's population was 4,266 people, including 2,318 males and 1,948 females.
As the senior (aged 65 and older) population was about 1,008 people, 23.63% of the total, the district can be called an aging community. The population changed and increased gradually from 5,559 people in 1946 to a peak of 9,175 people in 1969. From then on, population dropped rapidly.
Although there was a slight growth in 1993, the population at the end of 2003 was 4,315 people, the lowest over the years.
Population development of the district correlates with population change.
As Guanmiao is near Longci District and rattan factories offer higher wages, they have a significant effect on the economic activities of citizens in the district.
Over the past decade, therefore, the youth population of the district began migrating to Guanmiao to work as full-time, part-time or even domestic OEM employees for local rattan factories because Guanmiao is near Longci and those factories offered higher wages. As a result, the outflow of population was significant in Longci District.
Population migration between Longci, Guanmiao and Gueiren districts was very frequent after the 1990s. Information shows that Gueiren and Guanmiao districts were the most and second most popular destinations for population migration from Longci District in the industrial society period, particularly the "Sanbaihu" area in Nanbao Borough, "Liubaihu" area in Houshih Borough, Gucuo Borough, and Syucuo Borough in Gueiren District.
In conclusion, it is clear that as Longci Industry Park cannot offer suitable job opportunities for local citizens and due to the mass workforce demand of nearby districts' industrial development, the population outflow from Longci District is significant. In addition, as there is no urban planning for the district, where over 90% of the territory is slope land with protection areas restricting development, population reduction is common in the district.
