Part-time Workers as Primary Wage Earners
Including income from family members 18 and older, 45 percent of part-time workers in 2009 were the primary wage earner. This is almost a 50 percent increase from 1969. Part\xe2\x80\x90time workers earn, on average, less per hour than other workers with the same levels of education and experience, and are much less likely to receive either health insurance or pension benefits from their employers. This is in part due to the concentration of part\xe2\x80\x90time jobs in a limited number of low\xe2\x80\x90paying industries.
