The researchers chose three high schools of different socioeconomic statuses to examine: Star Spencer (low SES), Putnam City West (middle class), and Heritage Hall (upper middle class). Star Spencer had higher poverty rates and lower household incomes compared to the other schools. Putnam City West's demographics were more racially diverse than Heritage Hall. The researchers believe participation in high school sports leads to positive life outcomes like higher college attendance rates. Access to fitness facilities is important for students' health, development, and psychological well-being. Differences in facilities and participation rates across schools of varying socioeconomic levels could impact these benefits unevenly.
