The chart of the day shows the falling percentage of women in the ruling Communist Party’s Central Committee, a group of about 200 members that includes all seven men on the nation’s top decision-making body, the Politburo Standing Committee. Women accounted for 4.9 percent of the latest Central Committee unveiled last week, down from 7.6 percent in 1969, the year Nixon took office. Also shown is a ninefold surge in the number of women in the U.S. Congress during the same period.
