Keirsey Sorter Results - here
It should be noted that most people interested in personality type tend to be NFs, while the least common are SPs. Thus, this is pretty much a survey of people who are interested in type, hence the discrepency between the general population statistics. Also, I have rounded out the decimals into whole numbers.

Test Results from PersonalityPage.com - here
This site is not as popular as Keirsey's and also you have to pay for the test, so this is probably more accurate of those interested in personality type. Note that INFPs who make up 1% of the general population make up 13% of the people here. (We're just fascinated by this stuff, really.)
