More people moved to the U.S. from the Asia Pacific region in 2015, according to the most recent International Movers Study compiled by UniGroup Worldwide Moving.

The annual study by Missouri-based UniGroup tracks customers’ global migration patterns during the course of the preceding year.

Japan, the study found, saw a particularly large increase, jumping from number 10 in 2014 to the number-five spot in the ranking of number of moves to the U.S. last year.

Asia Pacific countries made up a third of the list of top origin countries for moves to the U.S. in 2015, with China, and Hong Kong maintaining their number-three and number-15 spots on the list. In addition to Japan’s upward move, India (number seven) and Singapore (number 10) also moved up the list two spots each.

“Americans continue to move to countries that have large and diversified economies, have experienced recent above-average economic growth or with whom the U.S. has had strong historical ties,” said Michael Stoll, economist, professor and chair of the Department of Public Policy at the University of California – Los Angeles.

In terms of moves to Asia Pacific countries, more Americans moved to China (number 3) compared to last year. However, international relocation to other countries in the region, including Japan (number 6) and Singapore (number 8), dropped.

According to the study, European countries continued to see a high volume of moves both to and from the U.S., with the U.K., Germany, France, and Switzerland topping both the destination and origin lists. On the list of countries sending residents to the U.S., however, the ranks of France (number 6), Switzerland (number 9) and the Netherlands (number 12) all fell.

Moves from Brazil increased as the country jumped from number 13 to number 8 on the top origins list. Puerto Rico entered the top 15 list of origin countries in 2015 at the number-11 spot.
