QUICK ANSWER

Blythewood and the Lake Murray corridor top the list.

Census and demographic data show that the Columbia suburbs experiencing the fastest population growth are those hugging the city’s northern and western edges. Blythewood, a small town along I‑77, has seen its population explode from fewer than 1,500 residents to over 5,700 — a 292.8% surge【937671397632031†L70-L87】. Further south, the Lake Murray corridor — including Lexington, Chapin and parts of Irmo — continues to draw new residents with its mix of lakefront living, top‑rated schools and suburban amenities. While statewide leaders like Hardeeville and Fort Mill post annual growth rates near 10%【856477046283282†L164-L173】, within the Midlands, Blythewood and the western lake towns set the pace.

Rising populations are more than a statistic: they signal where new housing, retail and infrastructure are coming. Buyers who understand the trajectory of growth can pick neighborhoods poised for appreciation and avoid pockets that may struggle with congestion or school overcrowding.
