Of the 54 such positions in OECD legislatures, women hold only 10 - a share of just 18.5% and only slightly above the worldwide average of 17.9% on 1st January 2016. The Netherlands is the only OECD country with women presiding in both upper and lower houses. Compared to 2010, when there were 8 female presiding officers out of 54, only two extra appointments have been made in the OECD (IPU, 2016). Numbers of female ministers, however, vary significantly from one year to another.
