Foreign-Born Population from China, by Age and Sex, for the United States: 2000
The age-sex pyramid of the foreign-born population from China (excluding Hong Kong and Taiwan) has many of the same characteristics of 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, 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 88 males to every 100 females. Unlike the Filipino immigrant population, however, the preponderance of females over males is not limited to the economically active ages of 25 to 54 but occurs in most age groups.
