Data Sources

Where did this data come from?

Joshua Project is not a formal research organization, but rather seeks to compile and integrate ethnic peoples information from various global, regional and national researchers and workers into a composite whole. Each of these sources may have varying methodologies, standards and levels of accuracy. Therefore, the margin of error may vary from data point to data point. While the data is the best available, numbers should be considered "ballpark." We are deeply grateful to these sources who have provided data to Joshua Project. Thank you!
