Since the 1990s, as part of the economic revival of interior China especially for the central and northwest regions, the city of Xi’an has re-emerged as an important cultural, industrial and educational centre of the central-northwest region, with facilities for research and development, national security and China’s space exploration program. Xi’an currently holds sub-provincial status, administering 9 districts and 4 counties.[6] According to the 2010 Census, Xi’an has an urban population of 5,566,711 in its built-up area made of 7 out of 10 districts (all but Yanliang, Lintong and Gaoling not urbanized yet),[7] while the total population of the Municipality is up to 8,467,837.[8][9] It is the most populous city in Northwest China, as well as one of the three most populous cities in Western China.[10] According to a July 2012 report by the Economist Intelligence Unit, it was recently named as one of the 13 emerging megacities, or megalopolises, in China.[11] The report pinpoints and highlights the demographic and income trends that are shaping these cities’ development.
