The progressive and innovative thinking that drives the world’s ninth-largest economy is not propelling women into top decision-making positions any more than the rest of the country.

On December 14, just a week after the UC Davis study of California companies was released, the nonprofit research group Catalyst published data showing that women occupy 16.1 percent of board directorships at Fortune 500 companies, about 6 percent more than at companies in California.

The same day, the InterOrganization Network—an alliance of 14 women’s business organizations that track women directors and executive officers of public companies based in their respective regions, reported that at 10 percent, California lags behind eight of the 14 regions in the percentage of board seats held by women.
