Knowledge

The IPU has been collecting data on parliaments since its inception in 1889, including information on women’s participation in politics since 1945. In this section, discover the IPU's knowledge bank for and about parliaments.

The IPU's publications are primarily meant for parliamentarians and policy makers. They range from general information, practical handbooks, to infographics. Many of the publications are available in multiple languages.

On Parline, the IPU has pooled all of its data into one hub, allowing the user to see trends over time, as well as compare progress or regression between different regions of the world. The data covers a wide range of themes; for example, the number of chambers, a monthly ranking of the women in parliament, the number of laws initiated by parliament and the average age of MPs.

The IPU also has a database of all its resolutions, declarations or outcome documents that underline a common position from IPU Member Parliaments.
