The NHL released its first-ever comprehensive diversity and inclusion report at its board of governors meeting on Tuesday, highlighting efforts to promote social change while offering a snapshot of its demographic challenges.

The 24-page report, titled "Accelerating Diversity & Inclusion," details the last two years of work by the NHL's Executive Inclusion Council and three subcommittees, which were created to examine and take action on diversity issues facing players, fans and hockey at all levels.

"We are working to better understand and accelerate our engagement across all layers of diversity -- including nationality, race, gender identify, sexual orientation, disability and religion," NHL commissioner Gary Bettman wrote in the report.
