Lost Springs residents said there were actually five people living in the town when the sign was made after the 2000 U.S. Census but they were unable to have it changed despite lobbying officials, The Casper (Wyo.) Star-Tribune reported Monday.
"None of us know exactly what happened," Mayor Leda Price said. "I made a lot of calls ... It was like everybody was passing the buck."
However, Price said the 2010 Census correctly counted the town's population at four residents and the Wyoming Department of Transportation is preparing to install a corrected a sign.
She said the change in official population doesn't make a difference for the town's revenue.
"For us it's just piddly," Price said.
