The Ohio State University and Oregon State University published their findings last month in the journal Sociological Focus. The study shows that female participation in youth sports has increased from 300,000 in the early 70s to now over 3 million. They said that socioeconomic status can often either foster or obstruct opportunities for youth sports among girls. Missing out on sports can have ramifications later in life, they say, including on collegiate and job opportunities, as well as the benefits of physical activity.
