Belgium & Europe:
This guide is written from Ghent, so European and Belgian sources are tracked separately rather than folded into the international list above.
- Transgender Infopunt - the Flemish reception, information and expertise centre for trans topics, based on the UZ Gent campus. Free and anonymous, and recognised by Equal Opportunities Flanders. If you are in Belgium and want to talk to someone rather than read a page, start here.
- Institute for the Equality of Women and Men (IGVM / IEFH) - the Belgian federal equality body. Publishes the official figures on legal gender-recognition in Belgium, and co-ran the 2024 survey on the living situation of trans and non-binary people in Belgium with Transgender Infopunt.
- ILGA-Europe, Rainbow Map & Index - annual ranking of 49 European countries on LGBTI law and policy, published each May. The source for the Belgium figures on our Legal & Political Landscape page.
