Note on the "Multicultural" category
The category of "multicultural" is too vague. After a cursory review of the churches in this category, some of the churches reflect urban diversity, such as the Montreal First, Toronto Rosewood, Cincinnati Clifton Avenue, Chicago Reach 77, and St. Louis Bridge of Hope. They might better be categorized as "urban" rather than "multicultural."
This designation also includes compassionate ministry centers which are not ethnic as much as affinity-based or need-based, such as the Kansas City Rescue Mission and Target Dayton.
Others could be designated by one of the specific ethnic categories, such as Lakota New Hope Ministries (Native American) or Iglesia del Nazareno Piedra Angular (Hispanic).
Just some suggestions in working through the data on ethnic churches.
According to a related study from Pew Research on racial diversity among U.S. religious groups published on July 27, 2015, the Church of the Nazarene reflects a membership that is 88% White with only 7% Latino and 2% Black. Nazarenes rank between Presbyterians and Unitarians on a diversity index. Assemblies of God ranks first among Evangelical Christian groups, and Methodists and Lutherans near the bottom of the list.
