Summary

Today, the number of children (under age 18) in the United States is at an all-time high of 74.2 million. But, the share of the national population who are children is at an all time low of 24%. Based on data from the 2010 census, we find that while there is a small increase in the number of children, the rate at which that population is growing has slowed dramatically over the past 20 years.
