Sustainable Cities: Advanced Technological Development Trends

Abstract

According to the United Nations Human Settlements Programme (UN-HABITAT), the population distribution by city size is categorized as follows: 1 to 5 million - medium-sized cities; 5 to 10 million - large cities; and 10 million or more - mega cities. The Market Intelligence & Consulting Institute (MIC) estimates that the populations of Taiwan's bigger cities in 2025 will be as follows: 4.1 million in New Taipei City; 2.8 million in Taichung City; 2.6 million in Kaohsiung City; 2.5 million in Taipei City; 2.3 million in Taoyuan City; and 1.8 million in Tainan City. All of them are classified as medium-sized cities, based on the UN definition. The Taipei-Keelung metropolitan area can be considered as a mega city from the perspective of regional planning.
