The National Hockey League evolved from a mono-ethnic and primarily Canadian professional athletic league to span North America.  The distribution of ethnic groups has been gradually changing since the inception of the NHL.  The league consists of a variety of players from varying nationalities and diverse backgrounds.  Once known as a league riddled with racism and exclusiveness, the NHL has made positive steps toward a more diverse and inclusive institution.  According to statistics, gathered by www.quanthockey.com, the NHL began its expansion of player nationalities in the 1970s, where players hailed from the United States, Sweden, and Finland.  The share of Canadians in the league dropped to 75% by the 1980s and is now slightly less than 50%.  The NHL is composed of 93% of players who designate themselves as white with the remaining 7% of varying ethnicities.  The NHL currently has 32 players of African-American descent.  Some notable NHL stars of African-American descent are Dustin Byfuglien, Evander Kane, and Joel Ward.
