Lancaster County is the 17th largest county in the state, according to revised Census estimates.
Lancaster County appealed the 2006 estimated county population, which was 63,628 and showed a .9 percent growth rate. The county building and zoning department and assessor's office put in a lot of work to prove the estimate wrong, said Lancaster County Administrator Steve Willis.
"The estimated growth was just impossible," Willis said.
Lancaster County has seen a major influx of newcomers in the last several years, most of whom are moving to Indian Land.
