Charleston Guides
Charleston County — the peninsula, barrier islands & inner suburbs
Downtown Charleston
Laid out on the 1680 "Grand Model" plan at Oyster Point, Charleston's historic peninsula is the walkable, flood-studied, earthquake-studied core the rest of the metro is measured against — home to Rainbow Row, the Battery, and the 1931 zoning ordinance credited as the first historic-preservation law in the United States.
Charleston CountyNorth Charleston
Incorporated in 1972 out of annexed federal land north of the peninsula, North Charleston is the metro's industrial and logistics anchor — the Port of Charleston's newest container terminal, Joint Base Lindsey Graham, Boeing South Carolina's 787 campus, and Charleston International Airport all sit within its city limits.
Charleston CountyWest Ashley
Charleston's largest suburb by population, built out after the Ashley River Memorial Bridge opened in 1926 and a 1950s postwar subdivision boom, on the same ground where English colonists' first permanent Carolina settlement stood at Albemarle Point in 1670.
Charleston CountyJames Island
A sea island between the peninsula and Folly Beach, split among the City of Charleston, the separately incorporated Town of James Island, and unincorporated county land — home to Fort Johnson, where a Confederate mortar fired the Civil War's opening shot on April 12, 1861.
Charleston CountyJohns Island
South Carolina's largest sea island — 84 square miles of Gullah Geechee farmland — is the metro's fastest-growing and most contested area, with nearly all traffic still funneled across a single two-lane Stono River bridge on Maybank Highway.
Charleston CountyFolly Beach
A separately incorporated barrier-island city 12 miles south of downtown, Folly Beach has called itself "the Edge of America" since its 1930s resort boom; Hurricane Hugo erased nearly every oceanfront home here in 1989, and an 800-license cap now limits short-term rentals.
Charleston CountyMount Pleasant
East of the Cooper River via the Arthur Ravenel Jr. Bridge, Mount Pleasant is Charleston's largest and most affluent suburb — 95,469 people (2025) around the Old Village's 1837 street grid, Shem Creek's shrimp docks turned restaurant row, and I'On, one of the country's earliest New Urbanist neighborhoods.
Charleston CountyIsle of Palms & Sullivan's Island
Two separately incorporated barrier-island towns joined by a bridge over Breach Inlet — Sullivan's Island is where a palmetto-log fort turned back the British fleet in 1776 — both with real, substantial flood exposure and among the most expensive ZIP codes in the metro.
Berkeley County
Daniel Island
Bought for $12 million in 1997 and built from scratch on a 4,000-acre island between the Wando and Cooper Rivers, Daniel Island is the metro's master-planned community — Blackbaud's world headquarters, Credit One Stadium's WTA tennis, and streets engineered a foot higher than the area's usual flood standard.
Berkeley CountyGoose Creek
Incorporated in 1961 to keep pace with growth around the adjacent Naval Weapons Station, Goose Creek is Berkeley County's largest city and the metro's working commuter suburb, built around Joint Base Lindsey Graham rather than a walkable downtown.
Berkeley CountyMoncks Corner
Berkeley County's seat on the roughly 60,000-acre Lake Moultrie, built by the Santee Cooper hydroelectric project between 1939 and 1942 — a small, car-dependent lake town of about 15,500 people and the most rural guide in this metro.
Dorchester County & the Summerville/Ladson corridor
Grouped here to keep the hub's three sections roughly even, not as a claim that all three share one county — Summerville is primarily Dorchester (with slivers in Berkeley and Charleston), Hanahan is entirely Berkeley County, and Ladson has no single governing county at all. Each guide's own "County" fact states its precise line.
Summerville
Incorporated in 1847 as a pine-forest retreat from Lowcountry malaria season, Summerville is the metro's fastest-growing large suburb — the historic "Flowertown in the Pines," whose Flowertown Festival draws roughly 200,000 visitors to Azalea Park every spring.
Berkeley CountyHanahan
Named in 1917 for the chairman of Charleston's public water works, Hanahan grew up around the Goose Creek Reservoir that still sits at its center — a compact Berkeley County suburb that didn't incorporate as its own city until a September 1973 vote, now home to 20,325 residents (2020 Census).
Berkeley / Charleston / DorchesterLadson
An unincorporated community split across Berkeley, Charleston, and Dorchester counties, Ladson grew up along the I-26/US-78 corridor next to Trident Technical College's original campus, with 15,550 residents at the 2020 Census.
Charleston metro snapshot
The facts below hold true across the whole Charleston metro, so they live here once instead of repeating across all 14 guides — each neighborhood and town guide links back to this section for the full picture, and keeps flood/insurance risk, utilities, and exact commute times on its own page, since those genuinely vary block to block in this market.
Population & counties
The Charleston-North Charleston, SC Metropolitan Statistical Area spans three counties — Charleston, Berkeley, and Dorchester — with an estimated 889,263 residents as of 2025, up from 799,636 at the 2020 Census. Its three principal cities are Charleston, North Charleston, and Summerville.
Transit
CARTA runs the metro's regular bus network. The free DASH trolley, launched in 2019, is limited to three routes on the downtown peninsula. Outside downtown, Walk Score rates most of the metro car-dependent — North Charleston scores 26, Mount Pleasant 22 — against downtown's 93 ("Walker's Paradise") for ZIP 29401.
Airport
Charleston International Airport (CHS) sits inside North Charleston's own city limits, annexed there in 1972 along with the former Charleston Naval Base and Air Force Base. The airfield shares its footprint with Joint Base Lindsey Graham, a roughly 24,000-acre joint Air Force-Navy installation formed in 2010.
Storm & earthquake history
Hurricane Hugo, which made landfall in September 1989, is the reference storm across this metro's guides — more than $2.8 billion in regional damage, the storm surge behind Mount Pleasant's flood maps, and nearly every oceanfront home on Folly Beach erased. The magnitude 6.9-7.3 earthquake of August 31, 1886, with an epicenter near present-day Summerville, killed 60 people and remains one of the largest ever recorded on the U.S. East Coast.
Notable places across the metro
On the peninsula: Rainbow Row, the Battery, and the Charleston City Market. On the barrier islands: Fort Sumter and Fort Moultrie National Historical Park, and the Folly Beach Fishing Pier. Inland: the Angel Oak on Johns Island, Magnolia Plantation and Drayton Hall in West Ashley, Credit One Stadium on Daniel Island, and Lake Moultrie in Moncks Corner.
