Gallup released its Potential Net Migration Index (PNMI) for 2010. The index considers the estimated number of adults who would like to move permanently out of a country subtracted from the estimated number who would like to move into it, as a proportion of the total population. The index is a result out of 350,000 surveys conducted between 2007 and 2010 and reflects how much the population would increase if countries dismiss their immigration restrictions. The index finds Singapore, New Zealand, Saudi Arabia at the top, and Sierra Leone, Haiti, Zimbabwe at the bottom.
