Yes. And if you read to the end of that section, you (a) discover that the changes were minimal "working hours dropping one percent for men, three percent for married women, and five percent for unmarried women" and (b) discover that the reason was "Mothers spent more time rearing newborns, and the educational impacts are regarded as a success. Students in these families showed higher test scores and lower dropout rates. There was also an increase in adults continuing education"
Which is how I described it in my comment.
