Land Area and Climate

Taipei City became 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 2012 was 271.7997 square kilometers. The population density of the city was 9,835 persons per square kilometer, ranking first in the country and far exceeding other cities and counties. Compared to other Asian 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 2012 was 23.2°C, which was 0.5°C higher than that of 2011. The highest and lowest monthly mean temperatures were 30.6°C in July and 15.8°C in January, respectively, showing a gap of 15°C. The annual number of precipitation days was 179 days and overall precipitation was 2,910.3 millimeters in 2012, which was a 65.49% increase compared to that of 2011.

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 2.67 million by the end of 2012, roughly 1.67 times of that in 1968. The sex ratio (male/100 female) has gradually dropped to 92.61 by the end of 2012, and is the lowest among the cities and counties of the country. The female population exceeds that of the male population, which is 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 2012, the aging index reached 91%, higher than that of Seoul, which is below 80%, and lower than that of Hong Kong, which is higher than 100%. The dependency ratio increased to 37.69%, 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 2012 was 4.85‰, an increase of 1.38 points from 2011, and its social increase rate was 3.51‰, a
decrease of 5.24 points from 2011 and the third consecutive year that the number of in-migrations exceeds the number of out-migrations.。
