Chinese-Born Population, by Age and Sex, for the United States: 2011

 The age-sex pyramid of the foreign-born population from China (excluding Taiwan) has many of the same characteristics as the "diamond shape" population pyramid of the total foreign born. This includes the largest number of immigrants in the economically active ages of 20 to 54 and relatively smaller numbers under age 20 and over age 54. Like the Filipino immigrant population but unlike the Mexican and Indian immigrant populations, the foreign-born population from China has fewer males than females. This is reflected in a low male-to-female ratio that indicates there were 84 males to every 100 females.

There were 1.87 million immigrants from China (excluding Taiwan) residing in the United States in 2011. Male-to-female ratio: 84.2.
