Why are there so few women as CEOs, senators, law firm partners, venture capitalists and hedge fund moguls, not to mention female executives lower down the chain?

Because we spend too much time with brooms in our hands, a new study says.

The Bureau of Labor Statistics’ annual Time Use Survey reveals that the percentage of men and women who are involved in household activities — defined as housework, cooking, cleaning up after cooking, and generally taking care of the household — has barely moved since 2003, when the bureau began tracking Americans’ day-to-day activities, Bloomberg reports.

Eleven years ago, 63 percent of men reported doing some household activity, while 84 percent of women did. In 2014, the numbers were almost the same, according to the statistics bureau — 65 percent for men and 83 percent for women.

According to the study, of those men and women who engaged in household duties at all, women spent about 2.57 hours on them each day in 2014, a decrease of 9 minutes over 11 years. Over the same period, men’s contributions have remained stagnant. In 2003 they spent 2.1 hours a day on housework, while in 2014 it was 2.11 hours.

The lack of movement is stunning, Bloomberg said, when one considers everything else that’s happened during the intervening period: Women now make up almost half of the U.S. labor force. In 4 out of 10 households with children, women are the sole or primary breadwinner, yet women not only face a glass ceiling at work — they face one at home, too.

On a positive note, Bloomberg reminds us that, according to the survey, at least more men seem to be into cooking.
