Those numbers can't be compared one is number of nobel prizes by the country they were born at. The other number of people who were at some point at Columbia University, i.e. alumni, faculty (past and current)... who won a Nobel prize sometime in their career. The total number of nobel prize winners counting the way the Columbia winners are counted would add up to many more than counting by country. In other words adding up all Nobel laureates by Country would yield the number of total laureates. Adding by alumni, past and present positions (at all universities) would yield a high multiple of total laureates, because the vast majority of laureates would not have spend their whole life at one institution.
