By the mid-17th century, the largest Jewish communities in the Western Hemisphere were located in Suriname and Brazil. Several Jewish communities in the Caribbean, Central and South America flourished, particularly in those areas under Dutch and English control, which were more tolerant. More immigrants went to this region as part of the massive emigration of Jews from eastern Europe in the late 19th century. During and after World War II, many Ashkenazi Jews emigrated to South America for refuge. In the 21st century, fewer than 300,000 Jews live in Latin America. They are concentrated in Argentina, Brazil and Mexico, with the first considered the center of the Jewish population in Latin America.
