In this article accompanying the above video, Eileen Patten says women were more likely to take career interruptions to care for their family, which can have an impact on long-term earnings:
Roughly four-in-ten mothers say they have taken a significant amount of time off from work (39%) or reduced their work hours (42%) to care for a child or other family member. Roughly a quarter (27%) say they have quit work altogether to take care of these familial responsibilities. (Fewer men say the same. For example, just 24% of fathers say they have taken a significant amount of time off to care for a child or other family member.)
Even though women have increased their presence in higher-paying jobs traditionally dominated by men, such as professional and managerial positions, women as a whole continue to work in lower-paying occupations than men do.
