Globally, women constitute approximately one third of scientific researchers , a ratio that has demonstrated minimal variation over the past decade. At the upper levels of scientific hierarchies , this proportion declines: for instance, only 12% of the members of the national academies of science are women. These percentages vary among countries, with no specific correlation between a country’s wealth and its success in achieving gender parity in science . The percentage of women scientists varies by region. According to the latest data from the UNESCO Institute of Statistics , this ranges from 23% of female researchers (in head counts*) in South Asia to 27% in Southeast Asia, 32% in sub-Saharan Africa, 34% in the European Union, 41% in Arab States, 44% in Latin America and the Caribbean, 47% in Central Asia and 52% in Southeast Europe.
