For years, data has shown gay men earning an average of five to 10% less than heterosexual people on the same position, but now the situation seems to have changed. Researchers at Vanderbilt University in Tennessee state that gay men started receiving a higher income. Gay men across the country now earn on average 10 percent more than their straight colleagues with the same working conditions, education and experience. Kitt Carpenter, an economics professor at Vanderbilt who co-authored the study, said the results surprised him a lot. The previous pay penalty which gay men suffered, he said, was received from different databases in such countries as UK, USA and Canada. One British study from 2014, for instance, found that gay men earn 9% less than straight men. And another from earlier this year discovered that the earning gap between gay and straight men still stood at 5%.
