For most candidates, the richest source of large individual contributions will be the most populous metro areas within their state or district.
Many incumbents also draw significant sums from the nation's capital.
Generally, they consist of central cities of 50,000 or more plus surrounding suburbs. Contributions from areas outside any metro area are not included, nor are contributions from PACs. All the numbers on this page are for the 1995-2000 Senate election cycle, based on Federal Election Commission data released on October 1, 2001.
