I guess this depends on what you consider low socioeconomic status. There is also a disparity in tertiary education. Women have higher enrollment and completion rates and thus get more degrees, even though sex ratio is skewed towards boys at birth.

For example in 2010 in the Netherlands (from http://barrolee.com/) 45% of women aged 30-34 have some tertiary education and 31% have completed tertiary education (31 / 45 = 69%) whereas the male statistics are 39% and 25% (25 / 39 = 64%). This is then offset by women working fewer hours per week (from Eurostat): in the Netherlands men average only 35 hours per week, and women only 25. Dutch working hours are a little extreme, but the general trend is worldwide.
