Comparative Data provides a systematic collection of how countries manage their elections. By presenting information about electoral systems, electoral management, legislative framework, voter registration, voter education and other related topics in a wide range of countries, users are able to compare, and identify common practice within electoral administration. Online, this unique data collection complements and enriches the body of electoral information currently being accessed on the ACE Electoral knowledge Network.

In addition to providing comparative information, this site is also designed to provide electoral country profiles, useful for electoral observation missions, media, and international organisations. Users are able to determine how the country's practices match or divert from regional/global practice.

The survey covers 11 election related topics and over 180 countries.
