<P> This is a list of the 100 largest counties in the United States by area . The list is based upon the total area of a county, both land and water surface, reported by the United States Census Bureau during the 2000 Census . Alaska is not divided into counties . </P> <P> A different ranking becomes apparent when comparing county areas by land area alone as opposed to total area . Some counties, such as Keweenaw and Alger Counties in Michigan, include significant amounts of water in their total area and would not appear on a list that considered land area alone . This list also includes the four counties that would be included when water area is not included . </P> <Table> <Tr> <Th> Rank </Th> <Th> County </Th> <Th> State </Th> <Th> County Seat </Th> <Th>
