SIL International has a survey service which operates across the globe in different administrative SIL units. I wonder, if the future of survey is no-longer looking at where indigenous people are living and what language variations they may have, but rather looking at where these people are going. Consider just the migrants from Nigeria according to lucify.com 89,032 Nigerians have immigrated towards Europe in the last 4 years. That is a lot of people. Where do those people come from? what languages do they speak? What linguistic load is being put on European governmental services? What could SIL offer to these governmental agencies? How could various social organizations benefit from SIL's often long standing work in the regions that these immigrants are coming from?
