According to the Association of American Residents Overseas (AARO), 26% of the US population moved their residence to Europe. A study was conducted using SRS and 150 people decided to participate. The sample resulted in 23% of the participants planning to migrate to Europe within the next two years.

No, the non-success is so much greater than success. No, the success is not sufficient.
