The delegates to the constitutional convention were, of course, all white men. About half had graduated from college. Most were investors or bankers of some sort whose financial interests lay with the value of stocks, or real estate. For most, the Constitutional Convention was not their first experience with government; most had experience serving in the Continental Congress or had served in Congress under the Articles of Confederation. Eighteen of the fifty-five delegates were in their twenties or thirties at the time of the convention, including such major figures as Alexander Hamilton (thirty years old) and James Madison (thirty-six). The average age was forty-two. I think it is fair to say that the delegates did not represent a "cross section" of the American public. Instead, they tended to be wealthy and educated; they were landowners, and, in some cases, slave owners -- in short, men with a stake in the economic and political stability of their new country.
