The Economist has put together an interesting map, based on data from the World Economic Forum, a Swiss think tank, showing the number of years each country has a had a female head of state or government. You might find the results surprising:
As with any data set, there are some caveats:
During that time period, just under two-fifths of the countries surveyed had a female head of state or government at some point for at least a year (excluding monarchs). In half of those countries, the total time served by female leaders falls short of five years, a common length of a single full term in office.
Like Hillary Clinton, who is the wife of a former American president, many female heads of state have hailed from political dynasties. At least a dozen are the wives or daughters of former presidents or prime ministers. They include the two women who, between them, have held the prime minister’s post in Bangladesh for 23 of the past 50 years—the longest any country has had women at the helm.
Moreover, the mixed bag of high ranking countries — ranging from developed democracies like Iceland and New Zealand, to more flawed democracies like the Philippines and Bangladesh — shows that greater representation for women in the upper echelons of power does not necessarily reflect, or translate to, more female empowerment and gender parity overall. (Especially if the women in power got there through proximity or political connections with men.)
