I realize it’s all an estimate. There’s no way to get an accurate statistic on undocumented people. It’s interesting to see how the estimates vary in collection methodology and results.

Colombia has not placed a cap on refugees fleeing a failing country. Also, there is a difference between an undocumented immigrant and a refugee. According to my research, Mr. Trump made the claim that there are 30 million undocumented immigrants living in the United States. However, the statistics indicate the number is closer to 11 million. Thanks for your feedback.
