According to a new study, urban areas are expanding at an increasingly rapid pace, outpacing even the growth of urban populations.  The study was published in the journal PLoS One and was conducted by a group of researchers from top American universities, including: Yale, Stanford, Arizona State and Texas A&M.  The study gathered a total of 181 previously published papers which measured the size of urban areas located around the world, between the years of 1970 and 2000. By collating this data and determining the annual rate of expansion, the researchers determined that urban expansion was most rapid in China and the Southwest Asian region. The study also notes that there were no signs of a global increase in urban land use efficiency or population density, therefore suggesting expansive urban growth globally.
