York County reached another population milestone last year, though its rate of adding new people has slowed compared with the rest of the region.
The U.S. Census Bureau estimates 303,001 people lived in the county on July 1 last year, according to new population figures published Thursday. It’s an increase of more than 4,600 people in a year and it’s the first time the county topped 300,000 people.
The 1.6% annual growth rate, though, is only No. 12 among South Carolina’s 46 counties. It’s also slightly below the state growth rate of 1.7%. York County’s rate is tied for seventh highest in the 11-county Charlotte metro area.
All those numbers are a shift for a county that’s been a growth magnet for more than a decade. Apart from a 1.1% growth rate in 2020, York County has grown between 1.4% and 3.2% each year since at least 2011.
Neighboring Lancaster County, which hit its own milestone a few years ago by topping 100,000 residents, had an estimated 111,652 people last summer.
That’s 2.6% more people in a year, the seventh highest rate statewide. The 16.3% growth since the 2020 Census is third highest in South Carolina, behind Jasper and Horry counties.
The one-year rate ties with Mecklenburg County as second highest in the Charlotte metro area, behind only Iredell County which grew at 3%. Lancaster County growth since the 2020 Census is easily highest in the metro area.
Lancaster County residential growth has been widespread throughout the Indian Land panhandle for more than a decade. Now, large subdivision projects like Edgewater, Roselyn and Riverchase look to expand growth throughout the county.

Across South Carolina, there were about 500 more deaths than births from mid-2023 to mid-2024. The overall population increase of 91,000 people came from movers to the state. About three-quarters of them came from other states, with the rest coming from other countries.
York County, though, is different. York County had 555 more births than deaths in a year, and 1,714 more births than deaths since the 2020 Census. While most people who moved to York County came from other states, nearly 35% of the net migration total came from international moves.
Lancaster County had 36 more births than deaths in a year, but 72 more deaths than births since 2020. International moves are a little higher than the state figure, but well below the rate in York County.
Chester County has had a mostly flat population for many years. The 32,323 estimated residents last summer is 23 more people than the county had in 2020. Deaths outpaced births in Chester County by 232 in a year and 957 since 2020. The steady population has come almost entirely from people moving from other states.
The Census Bureau will release new estimates for cities and towns later this year. But driving through the Rock Hill region makes it clear there’s more growth to come.
Along with those big Lancaster County subdivisions, homebuilder Lennar is clearing property opposite Fort Mill Parkway from its Elizabeth subdivision for a second phase in Fort Mill. Tega Cay is creating a new Main Street at Dam Road and Stonecrest Boulevard. Lake Wylie, Rock Hill, York and Clover have new home projects.
In Lancaster County, there are more than 26,000 lots in subdivisions where a home is allowed, but hasn’t yet been built.
Here are more facts about growth in the Rock Hill region, from the new census estimates:
? York County is the seventh largest county in South Carolina. Greenville, Charleston and Richland are the largest. Lancaster County is No. 15 and Chester County is No. 29. That’s one spot higher for Lancaster and lower for Chester compared with the 2020 Census. York County didn’t change.
? Only Mecklenburg County, with 1,206,285 people, has more residents than York County within the Charlotte metro area. Union, Cabarrus, Gaston, Iredell and Rowan counties in North Carolina, in that order, have more people than Lancaster County does.
? The nation has 3,144 counties or equivalents (Louisiana has parishes, for instance). York County ranks No. 242 in population, or in the top 8% nationwide. Lancaster County is No. 573 and Chester County is No. 1,387.
? The nearly 447,000 people who live in York, Lancaster or Chester counties would make up almost half the population of Charlotte.
? York, Lancaster and Chester counties added a combined 7,642 residents in the year ending last July 1. That’s a couple hundred more people than the entire population of Clover. The 36,752 more Rock Hill region residents since 2020 is more people than live in Fort Mill.
? South Carolina has the second largest York County. It trails York County, Pennsylvania with its 471,240 people but has more than fellow namesake counties in Maine (220,143), Virginia (71,410) and Nebraska (14,375).
Likewise, Pennsylvania (563,293) has the largest Lancaster County. Next are Nebraska (332,857), South Carolina and Virginia (11,062). South Carolina’s Chester County slots in between others in Pennsylvania (560,745) and Tennessee (17,876).
