I found this to be incredible (from the June 25 print edition of the US News & World Report, read while on the exercise bike at my parents’ the other day):

The problem: too many people and not enough different names. As a result, China may soon try to reduce name confusion in a country where most of the 1.3 billion people share just 100 family surnames. For instance, 93 million Chinese have the surname Wang, the most common, and 92 million have the surname Li. A newborn can take the surname of either the father or mother, but now officials are considering also permitting a combined surname, such as Wangli or Liwang. (Emphasis added.)

93 million? Good God. Truly amazing.
