Today, there are 146 national PEN centers in the world. The International PEN Headquarters, which coordinates and advises other centers, is located in London. The largest PEN center in the world is the American one, with 7,200 members.
Priorities in the activities of national PEN centers can be determined by the cultural and political situation in a particular country.
Every autumn, the International PEN organizes a PEN Congress in one of the world's countries, bringing together leaders and members of other national PEN centers to re-elect international leadership and adopt PEN human rights resolutions. In 2017, the International PEN Congress was held for the first time in Ukraine (Lviv), in 2018 - in India (Pune).
