Explanation and answer:
Today, there are almost 42 million adolescents between the ages of 10 and 19 in the United States, and adolescents make up 12.9 percent of the population.1 As the U.S. population ages, adolescents will represent a smaller proportion of the total. By 2050, estimates show that adolescents will make up 11.3 percent of the population.1 While adolescents are predicted to represent a smaller portion of the total population, estimates show that the number of adolescents in the population will continue to grow, reaching almost 44 million in 2050.1
