This slide shows the percent of students who enrolled in higher education in 2016, broken down by gender, ethnicity, and income status. There are clear income effects shown in this slide, with low income students typically enrolling in higher education 20% or 30% less than non-low income students. Females generally enroll in higher education more frequently than males. The only apparent ethnic differences involve Asian students, who enroll in higher education more frequently than other ethnicities. 
Particularly distressing are the low enrollment rates of low income males.  With the exception of Asian students, all ethnicities of low-income male students enroll in higher education at rates of less than 40%.
