Okay. Let me put it in other words.

There are more people between the ages of 15 and 35 in China than there are people alive in the United States.

There are more 20 year-olds in China than there are men in Taiwan.

You don't need conscription to fight a naval war when you have almost a billion and a half people. Your demographics support finding enough volunteers.

Also, the one-child policy put China's fertility rate at 1.70 children per woman. You know what the US fertility rate is?

1.70 children per woman.

Taiwan's fertility rate? 1.2 children per woman.
