Why is the population growth in the United States slow? A netizen's question has sparked widespread discussion.

This question from an American netizen made me immediately have some doubts: Why is the population growth in the United States so slow?

This is a question from an American netizen on Reddit: "In our country, 40% of families have two or three children. I know that China has implemented a three-child policy. How many families in China have three children?"

Okay, let's summarize a few conditions: 40% of families in the United States have three children, the life expectancy of Americans is 81.7 years, and millions of immigrants come into the United States every year. PS: Please pay attention to the trap of wordplay. The United States has never released its average lifespan; it always releases the life expectancy, with the addition of the word "expected," which is a completely different concept.

So, you see, the number of new people added to the population each year in the United States should be very significant, but the population of the United States has always remained around 340 million. So where do the number of new people added to the population each year go?
