Appendix II Statistics

Land Area and Climate

Taipei City was upgraded to a centrally-administered municipality under the Executive Yuan, R.O.C., in July 1967. After several boundary readjustments, the land area of Taipei City by the end of 2014 was 271.7997 square kilometers. The population density of the city was 9,942 persons per square kilometer, ranking first in the country and far exceeding other cities and counties. Compared to other Asia cities, the population density is between Hong Kong and Seoul.

Taipei City is located in the subtropical zone with year-round rain and no obvious dry seasons. The climate is usually damp and cold during the wintertime due to the influence of the northeast monsoon. The temperature rises during the summertime, since Taipei City is located in a basin that does not allow for regular ventilation. The mean temperature of Taipei City in 2014 was 23.5°C, which was 0.1°C higher than that of 2013. The highest and lowest monthly mean temperatures were 30.5°C in July and 16.5°C in February and December, respectively, showing a gap of 14°C. The annual number of precipitation days was 140 days and overall precipitation was 2,147.3 millimeters in 2014, which was a 15.51% decrease compared to that of 2013.

Population Profile

The registered population in Taipei City was 1.6 million when its urban districts were restructured and expanded in 1968. The population increased to 2.70 million by the end of
2014, roughly 0.68 times of that in 1968. Having gradually dropped, the sex ratio was about 92 male to 100 female and was the lowest among the cities and counties of the country by the end of 2014. The female population exceeds that of the male population, which was the same as Hong Kong, Singapore and Seoul. In terms of age, the proportion of the old has been increasing annually, while the proportion of the young has been decreasing. By the end of 2014, the aging index reached 99.41%, higher than that of Seoul, and lower than that of Hong Kong. The dependency ratio increased to 39.37%, similar to that of Hong Kong and Singapore.

Two factors influence the fluctuation of the total population, which are natural increase (birth and death) and social increase (in-migration and out-migration). Taipei City's natural increase rate in 2014 was 4.40‰, an increase of 0.54 point from 2013, and its social increase rate was 1.47‰, an increase of 0.37 point from 2013 and is the fifth consecutive year that the number of in-migrations exceeds the number of out-migrations.
