This survey was conducted to better understand the lives of lesbian, gay, bisexual, transgender, and intersex (LGBTI) people in seven countries in Southeastern Europe: five in the Western Balkans-Albania, Bosnia and Herzegovina, Kosovo, FYR Macedonia, and Montenegro; as well as two European Union (EU) member states, Croatia and Slovenia. The research adopted and adapted a 2012 survey of LGBT people carried out by the European Union Agency for Fundamental Rights (FRA) in 27 EU countries plus Croatia (which joined the EU in 2013) (the “FRA survey”). The FRA survey set a benchmark for understanding the lives of LGBT people. In addition to the FRA survey, this current survey also gathered specific information on the lives of intersex people. The collective experiences of LGBTI people in the countries surveyed paint a distressing picture of the harmful effects of discrimination, harassment, exclusion, and violence. Despite the frequent discrimination, harassment, and violence that LGBTI people face, specific incidents are seldom reported. Even though five years have passed since the FRA survey, the situation for LGBTI people in the Western Balkan countries is much worse than the experience of their peers in the EU, across nearly all dimensions. This is the largest survey of LGBTI people ever carried out in Southeastern Europe. A total of 2,296 people responded.
