The U.S. Census Bureau says Franklin County is now Ohio's most populous county.
The Bureau says the county added more than 14 thousand residents last year. But Ohio's overall population growth rate is ranked 40th in the nation, well behind warm-weather states like Texas and Florida. Ohio added 9 thousand people last year. Columbus is ranked 33rd in terms of metro populations, while Cleveland is ranked 32nd. Bureau officials and economists say Columbus' population has been growing steadily since the early 1990s because the city is a government town and a college town, which means people come here to work and study.
