This map of where nurses work does not necessarily reflect where they were trained. Medical staff may train in poorer territories and migrate to where there is better payment for their work. Often they send funds home.
The United States, China and the Russian Federation are where the largest number of nurses work. However, the highest numbers of nurses per person can be found in Western European territories such as Finland and Norway. The fewest nurses working per person in the population are in Haiti, Bangladesh and Bhutan; territories where there is much more need for nurses than is found in many other places.
