How is south asia's urbanization different from that of east asia?

Urbanizations in South Asia differ greatly from those in East Asia, mainly for three reasons:

-The cities of East Asia are much more densely populated than the cities of South Asia. In East Asia, the population is located at 90% in cities, while in South Asia the urban population only reaches 70%. For example, 30% of the population of Japan (40 million people) live in the Tokyo Metropolitan Area, its capital; while 6% of the population of India (82 million people) live in its most important metropolitan areas (New Delhi, Mumbai, Calculta, Bangalore, Chennai, Hyderabad and Ahmedabad) grouped together.

-The cities of East Asia have a much higher standard of living than the cities of South Asia. For example, Lahore, Pakistan, has an HDI of 0.877 while Hong Kong has an HDI of 0.933.

-Finally, the cities of East Asia are avant-garde at the technological and economic level. Cities such as Tokyo, Shanghai, Seoul, Hong Kong or Taipei are mecca of business and entertainment, as well as top-notch industrial and technological poles. On the other hand, the cities of South Asia are quite delayed in terms of economic and technological production.
