Where should Christians prioritize work and prayer to see the least-evangelized peoples in North America reached with the gospel? Below is a list from a working spreadsheet that attempts to determine the most significant unreached people group communities in North American cities where missionaries are needed. The list is sorted using an overall significance score based on a matrix of weighted factors including global status of evangelical Christianity, population size in the city, ministry engagement in the city, same culture Christians in the city, and the global significance of the people group’s presence in the city. To access the working spreadsheet on google docs, click here. Within the spreadsheet, you will see an explanation of the factors above, the weight assigned to each factor, and how the people groups scored for each factor. Visit our FAQ page for answers to frequently asked questions about the UPG Matrix. If you have information (even if incomplete) on an unreached people group in a North American city that should be added, or edits you feel should be made, please submit the information through this form (the people group must number at least 5,000 in the city to be included).
