About 0.7 percent of children in China aged 6 to 12 have autism, suggests the largest study of the country’s autism prevalence to date1. And in Greece, 1.15 percent of 10- and 11-year-olds have the condition, according to the first estimate for that country2.
Both figures fall within the range of autism prevalence estimates reported for children in other nations. The studies also show that autism is about four times as common in boys as it is in girls in both countries, a ratio in line with studiesof children in the United States and elsewhere.
