Starkville is now the largest city in the Golden Triangle, outpacing Columbus by a little over 240 residents, Census 2010 data shows.
Mississippi was one of the first states to receive its numbers from the U.S. Census Bureau from last year's count of the nation's population.
The data became available online Friday.
Starkville, the home of Mississippi State University, now has 23,888 residents, a gain of 8.4 percent over 2000's 21,869.
Columbus, who led the region with 25,944 in 2000, now has 23,640 residents, a loss of 8.9 percent.
West Point, the northern point on the Golden Triangle, lost 6.9 percent of its residents from 2000 to 2010, going from 12,145 to 11,307.
Two of the Golden Triangle's three counties lost population.
Lowndes and Clay counties lost 2.9 percent and 6.1 percent respectively. In 2000, Lowndes County had 61,586 residents, while in 2010, the county recorded 59,779 people. Clay County showed 21,979 residents in 2000, while it had 20,634 residents last year.
The region's big gainer in county population was Oktibbeha County, with a 10 percent increase from 2000's 42,902 to 2010's 47,671.
Jon Maynard, the Greater Starkville Development Partnership's president and CEO, responded to the numbers regarding Starkville and Oktibbeha County Friday afternoon.
"The message is clear that Starkville and Oktibbeha County are growing. The progress that has been made shows that Starkville, the county, its businesses and the university are working together to create a better place to live and work.
We've working very hard to build our economy and continue the growth far into the future," Maynard said.
On Friday afternoon, Starkville Mayor Parker Wiseman also shared his thoughts about the numbers.
"It's great news. It shows we are a healthy, growing community. Starkville's one of the 15 largest communities in the state of Mississippi, one of the fastest growing communities in the state. I think it's wonderfully positive news about the direction of this community. There's certainly an energy and enthusiasm that you can sense about the direction of this community, but it's always nice to see numbers bear that sense out," he said.
As a whole, the region's main three cities lost population when counted together, from 59,958 in 2000 to 58,835 in 2010 â€“ a percentage loss of 1.9 percent.
