That's an interesting figure they've got!
Observations (based on the figure alone):
1. White-Males had the lowest college-enrollment-rates across all categories. They got the lowest in the two lowest income-brackets; basically a three-way tie in the next income-bracket; and just a little higher than Hispanic-Males in the highest income-bracket.
2. Asians had the highest enrollment-rates across all income-brackets.
3. Asians were relatively constant in their enrollment-rates, regardless of income or gender, always above 70%. (Always above ~83%, if excluding the lowest income-bracket.) The gender-gap still leaned toward Asian-Females over Asian-Males, but not by much.
4. Blacks varied heavily by income. Blacks had pretty low enrollment-rates in the lowest income-bracket, but got some of the highest enrollment-rates in the higher income-brackets (after Asians).
5. Black-Females had an odd pattern-deviation: like Black-Males, their enrollment-rates increased dramatically with family-income, getting the highest non-Asian enrollment-rate by the second-highest income-bracket. But then, oddly, their enrollment-rate fell by ~8% from the second-highest to the highest income-bracket.
6. Hispanics were pretty consistent with Whites, especially for Males. For Females, Whites had higher rates in the lowest income-bracket, while Hispanics had somewhat higher rates in all other income-brackets.
7. Ignoring race, enrollment-rates increased significantly with family-income.
8. Ignoring race, enrollment-rates were much higher for Females than Males across all income-brackets.
