Apparently there’s enough vacant housing in China to accommodate nearly the entire adult population of the United States. Doesn’t sound too optimal to me!

Recent statistics show that there are about 64 million apartments and houses that have remained empty during the past six months, according to Chinese media reports. On the assumption that each flat serves as a home to a typical Chinese family of three (parents and one child), the vacant properties could accommodate 200 million people, which account for more than 15% of the country’s 1.3 billion population. But instead, they remain empty. This is in part because many Chinese believe that a home is not a real home unless you own the flat.
And so people prefer buying to renting, and as a result, the rental yield is relatively low.
