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 2013 was 271.7997 square kilometers. The population density of the city was 9,884 persons per square kilometer, ranking first in the country and far exceding other cities and counties. Compared to other Asia cities, the population density is between Hong Kong and Osaka of Japan.
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 in Taipei City in 2013 was 23.4°C, which was 0.2°C higher than that of 2012. The highest and lowest monthly mean temperatures were 29.6°C in August and 16.4°C in December, respectively, showing a gap of 13.2°C. The annual number of precipitation days was 158 days and overall precipitation was 2,541.4 millimeters in 2013, which was a 12.68% increase compared to that of 2012.

The registered population in Taipei City was 1.6 million when its urban districts were restructured and expanded in 1968. The population increased to 2.69 million by the end of 2013, roughly 1.67 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 2013. The female population exceeds that of the male population, which was similar to figures for Hong Kong, Singapore and Seoul. In terms of age, the old age population has been increasing annually, while the young age population has been decreasing. By the end of 2013, the aging index reached 94.53%, higher than that of Seoul, and lower than that of Hong Kong. The dependency ratio increased to 38.46%, similar to that of Hong Kong, Singapore and Jakarta.
Two factors influence the fluctuation of the total population, namely natural increase (birth and death) and social increase (in-migration and out-migration). Taipei City’s natural increase rate in 2013 was 3.86‰, a decrease of 0.99 point from 2012, and its social increase rate was 1.10‰, a decrease of 2.41 point from 2012 and is the fourth consecutive year that the number of in-migrations exceeds the number of out-migrations.
