For employed mothers with a high level of educational attainment, this is 72.2% - a difference of just under 8 percentage points. Being unmarried also significantly increases the likelihood of an employed mother working full-time, although the size of the association here is only small. On average, holding all else constant, the probability of working full-time rather than part-time is only about 2 percentage points higher for unmarried mothers than for married mothers. Age has less of an effect - there is no significant difference in the probability of full-time employment across age groups, at least after controlling for other factors.
