Hi Mike asked about what denominator was used to arrive at 1.25%. If you go to the tables he linked to you will find that total column gives value of 196,305,000 for 25 years and over. This is the value Mike used in the denominator below (in thousands, the same as the numerator). The ENTIRE population of the USA was about 300,000,000 in 2008. So the percentage PhDs in the population 25 and older is 1.25%, as Mike indicated. The percentage among billionaires is much higher.

Is 1.25% significantly different from 3.96% (i.e., 4/101)? Take care Jim --- To make changes to your subscription contact: Bill Southerly (bsouthe...@frostburg.edu)
