Doctorate degree holders increase 45 percent

PhD stripes being conferred more often.

From 2002 to 2012, the highest rate of increases in education attainment levels were doctorate and master’s degrees, according to new statistics from the U.S. Census Bureau. The population with a doctorate grew by about 1 million, or 45 percent, while those who held a master’s climbed by 5 million, or 43 percent.

Although many doctoral programs offer full tuition waivers and stipends, it costs about $20,000 per year to be involved in a PhD. program.

Meanwhile, the population with an associate degree rose by 5 million, or 31 percent. Those whose highest degree was a bachelor’s degree grew at a smaller rate: 25 percent to 41 million. Meanwhile, the number of those without a high school or GED diploma declined by 13 percent, falling to 25 million.

Women outnumbered men in 2012 among people whose highest level of education was a bachelor’s degree (21 million versus 19 million) or a master’s degree (9 million compared with 7.4 million). Conversely, more men had doctorate (2 million versus 1.2 million) or professional degrees (1.8 million compared with 1.2 million). Between 2002 and 2012, however, the gap between the number of men and women with professional degrees shrank.

The statistics come from Educational Attainment in the United States: 2012, a series of national-level tables showing attainment levels by a wide range of demographic characteristics, including sex, race, Hispanic origin, marital status, household relationship, citizenship and nativity, labor force status, occupation and industry.

The tabulations also show that education continues to pay off. Among people 25 and older who had any earnings in 2011, average earnings were $59,415 for people with a bachelor’s degree (but no graduate degree), compared with $32,493 for people with a high school diploma, but no college.
