By 2015, at the rate of 35 million people per year moving to the cities, China would have 900 to 950 million in the cities and towns and 65-68% urbanization.
I believe the faster than expected rate of urbanization is also driving the growth of China's economy at faster than expected rate.
The small towns will accommodate 200 to 300 million, and the other 600 million will go to cities. To accommodate the 600 million people, 200 big cities, each holding over 300 million, or 300 cities each supporting 200 million are needed," predicts Lian Yuming, Director of the Beijing International Institute for City Development at the Beijing Summit of China City Forum.
The law of city development in the world indicates that urbanization process will start to accelerate in a country when its per capita GDP exceeds US$ 1,000; as the per capita GDP exceeds US $ 3,000, the development will rise rapidly.
More recent statistics show that small town populations increased 27.5% from 2000 to 2005
China is expecting 24 million new job seekers in cities and towns this year However, only 60% of the population is employed. So the young people moving to the cities and towns could find a job and then a fraction of them could move non-employed family over. Again consistent with about 30-35 million people moving to the cities and towns each year.
