Demographics from The Personality Questionnaire

On occasion we gather voluntary demographic information from individuals who take The Personality Questionnaire. We have generated some interesting statistical information from data we have gathered thus far. This data was gathered from people who took The Personality Questionnaire in the year 2000; 22,000 who volunteered personal data were included. Numbers are skewed to the year 2000 and are representative of the internet community rather than the public at large.
