Many migrants today travel farther distances, consciously seeking cities of choice – a sociological metric designed by Boston Consulting Group (BCG) that measures and determines opportunity and quality of life. Observed in the aggregate, these migrants are more diverse than ever before and have in-demand vocational skills. They are also becoming more sought-after.
