Census Bureau has put Mohave County back in Arizona.
In the Census Bureau world of metropolitan statistical areas, the county had been considered part of Las Vegas.
But because of the new statistical category of micropolitan statistical area, the county will be in a world of its own in terms of Census Bureau data, which affects subsidy levels for programs such as housing.
"Rent subsidy levels in Kingman have been higher because Las Vegas housing costs were included," said Dave Barber, deputy director of the Western Arizona Council of governments.
"That would likely change without the Nevada numbers."
A micropolitan statistical area is defined as a region with at least one urban area of more than 10,000 but less than 50,000 population.
Among other changes announced by the White House Office of Management and Budget last week as a result of the 2000 census, Prescott and Yavapai County became one of 49 new metropolitan statistical areas in the nation.
Areas in Arizona already considered metropolitan are Phoenix-Mesa-Scottsdale, Tucson, Yuma and Flagstaff.
Lake Havasu City, the most populated area in Mohave County, is expected to reach 50,000 population prior to the 2010 census.
Mohave County had a population of 155,032 in the 2000 U.S.
Census, making the Lake Havasu-Kingman micropolitan area the third most populous in the United States.
The most populous is Torrington, Conn, at 182,193.
Mohave County could be the largest geographical area in one micropolitan statistical area because the county is one of the ten largest in the country.
Some Kingman city programs include eligibility income figures that could change, Kingman grants coordinator Bill Shilling said.
"The Kingman CDBG (Community Development Block Grant) housing program includes income guidelines that might be lower without Las Vegas data," Shilling said.
"It makes our job easier to have all the Lake Havasu-Kingman Micropolitan Statistical Area separate from Clark County, Nev.," Betty Jefferies of the state Department of Economic Security said.
"It was difficult to separate out-state data,"
Jefferies, a data analyst, said data would be better targeted to the area and likely makes it easier for agencies in the county to find and use data.
