Bloomberg’s Singapore‐​based columnist Andy Mukherjee writes about the private‐​education boom in China:

At the end of 2005, some 15 million students were enrolled in 77,000 non‐​state schools. That’s 8 percent of the 197 million Chinese children aged 5 to 14 years. Privately funded schools in India have twice as large a share of the total market.

Expect the gap to close quickly.

Nine years ago, Ma Lei of Fudan University wrote about the growth of private schools in China for Cato Policy Report:

In Wenzhou, more than half of the 600 million RMB spent on education comes from the private sector. That’s a claim that few, if any, communities in the United States can make. …There are more than 2,300 privately run kindergarten classes in Wenzhou, in which more than 90 percent of all children of kindergarten age are enrolled. In addition, there are 21 private high schools, which educate about a quarter of the total high school student population.

James Tooley has also written at length about private education for the poor in Africa and India. His work, and its exciting new directions, are discussed in this Atlantic article.
