The Census figures income by "household." The top 2% of households has an income of $250,000+. But those households are racially different. The wealthiest households in the U.S. are Asian (they also have the largest households). 4.2% of Asian households are in the $250,000+ group; 2.1% of white households; .9% of Hispanics; and .6% of blacks. What else isn't equal? Married couple households. Asian households are 63.2% married; whites 58.1%; Hispanics 55.1%; and 34.8% blacks. It's probably basic math, but two workers make more than one. 64% of college graduates are married, compared to 48% of high school graduates; in 1960 the difference was 76% and 72%. But it’s also apparent that there are some very wealthy, unmarried, single households not sharing their wealth with anyone.
Also, whites have the lowest college enrollment of all ethnic groups in the U.S. The number of female Americans enrolled in college was significantly higher than the number of males (11.3 million versus 8.6 million). That was not only due to higher population figures for females: 7.4% of the 3+ female population was enrolled in college, compared to 5.9% of the 3+ male population.
Black Americans demonstrated higher-than-average college enrollment rates, at 8% of the 3+ population – equaling just over 3 million enrolled. Female black Americans had a substantially higher enrollment rate (9.2% of the 3+ population) than their male counterparts (6.5%).
Non-Hispanic whites had the lowest enrollment rates. 6.2% of the 3+ group was enrolled in college last year, with females outpacing males (6.8% vs. 5.5%). A total of 11.65 million were enrolled in college.
