China & India Urban Residential Floor Space in 1993, 2002, 2008

Excerpt:

Average income growth has been a key reason behind these different trends in the quality of the housing stock. The urbanisation process in China has transferred large numbers of workers from relatively low productivity jobs in the rural sector to higher productivity jobs in urban areas. This movement has been a driver of the rapid growth in incomes in China over the past three decades, which has far exceeded the growth in incomes in India (Graph  7). Over time, Chinese households have chosen to spend their higher income on higher quality dwellings and dwellings with larger floor space and, as a consequence, the share of concrete dwellings and residential floor space per capita has increased.
