LGBT people have seen a rise in tolerance in almost every region of the world over the last decade, according to an index released on Monday.

Iceland was named as the most tolerant country toward LGBT people in a survey of 167 countries by British think tank the Legatum Institute, while central Asian country Tajikistan was the least tolerant.

"It is encouraging to see that our 2019 Prosperity Index shows a rise in tolerance towards the LGBT community globally over the past decade," Shaun Flanagan of the institute's Center for Metrics said.
