This article outlines the composition by sex of political scientists in the UK. The data show that there are fewer women working in the profession than men and that there is a ‘seniority sex gap’. The data are then broken down in terms of university membership groupings and individual departments in order to produce snapshot rankings. These rankings are then combined to produce an overall ranking of female presence within UK political science departments. Our findings suggest that a ‘leaking pipeline’ persists and that numerical and seniority inequality will continue for a considerable time unless further action is taken.
