Sometimes hard facts are difficult to come by but this insight into the data from Canada stacks up at an economic level. There is no reason why this would not be replicated at an employee & country level.
Our findings show a pronounced diversity dividend. Specifically, we find that a 1 percent increase in ethnocultural diversity among employees is associated with an average 2.4 percent increase in revenue and 0.5 percent increase in workplace productivity across 14 industries. Businesses that welcome diversity show an increase in their economic bottom line. The sectors reaping the greatest benefits from ethnocultural diversity include business services (e.g., administrative, tech, law, and insurance firms), information and cultural industries (e.g., publishing, broadcasting, arts, and telecommunications companies), and transportation, warehousing and wholesale enterprises. These sectors experienced 6.2 percent, 3.6 percent and 4.1 percent growth in revenue, respectively, for every 1 percent increase in ethnocultural diversity in the workplace.
