This is anecdotal, I realize, but a summer class started this morning. Like most classes, the full roster in front of me did not correlate with a full classroom. Each first day, some students don't show up. There's been a nagging trend: most of the people who don't show up are women. In fact, almost all of the ones who didn't show up to my class this morning were women.
Obviously, being a woman doesn't necessarily mean that you're a mother, and being a mother doesn't necessarily mean that you're the only caregiver available for your child. Still, it seems that a lot of the students who disappear mid-way through the semester are also women, women who have often been struggling to find stable childcare.
