Per Wikipedia.....A 1992 census found that, for U.S. public water supply systems reporting the type of compound used, 63% of the population received water fluoridated with fluorosilicic acid, 28% with sodium fluorosilicate, and 9% with sodium fluoride.

I know the above figures are not correct since it does not account for houses that use wells. The house I used to live in had well water as did everyone else within a 10 mile radius. When I attempt to find out how many households depend on wells I get several different figures, up to 10% of the population.
