This paper develops a decomposition framework to access the relative contributions of demographic factors to urban land growth in China. The results suggest that changes in total population, average household size, urban proportion of household, and average urban household density respectively accounted for 20.2%, 29.0%, 67.3%, and -26.3% of the change in the total amount of urban land between 1988 and 2005. A further decomposition shows that the net effect of regional disparities in the extent of rural-urban migration was negative. There is a large degree of heterogeneity across individual provinces in the relative importance of these components.
