Worldwide data indicate a positive correlation between the density of PhD holders in a country’s population and its economic prosperity (GDP per capita). In broad terms, nations that invest heavily in higher education and produce more doctoral graduates tend to be economically better off. For instance, Slovenia and Switzerland rank among the highest in PhD holder share (roughly 5% and 3% of their populations, respectively) and also enjoy relatively high income levels
