Who lives in Charleston, South Carolina?

Charleston is a roughly 150,000-person coastal city spread across the lower peninsula where the Ashley and Cooper rivers meet the Atlantic, the historic core of the South Carolina Lowcountry. The age curve sits close to the national shape with a slight lean young, the 25-34 band carrying about 23% of residents against roughly 20% nationally, the kind of tilt a town with the College of Charleston and a teaching hospital tends to hold. Women make up a little over half the population.

What separates this audience is not who they are on paper but how seriously they tend their own health. More than a quarter score as obsessive about it, close to three times the national share, and the same instinct turns up in how they handle care: about 35% take a proactive approach, screening and checking in before anything is wrong rather than waiting for symptoms. A city built on water and walkable blocks rewards that habit.

Curiosity runs a touch high here. Openness sits several points above the national mark, a willingness to try the unfamiliar and chase what is new rather than settle for the proven, which fits a place that turns over restaurants, festivals, and storefronts at a fast clip. Conscientiousness leans up as well, the planning-ahead streak you would expect from people who schedule their own preventive care.

The rest of the temperament holds near the middle of the country. Warmth toward strangers and outward sociability both land within a point of baseline, so Charleston is neither notably reserved nor notably gregarious. Sensitivity to stress runs slightly elevated, a low hum rather than a defining trait.

Ethics show up at the register more than in most places. Only about a fifth of residents skip ethical considerations when they buy, well below the national norm, and roughly three in ten weigh them regularly. That conscience extends to the coast itself: environmental concern runs above average, with a third actively engaged, fitting for a population that lives between two rivers and a rising tide.

The one value that runs the other way is loyalty to local merchants. Strong preference for independent shops sits below the national rate, which reads less as indifference than as the reality of a city where so much retail is built for the seven-million-plus visitors who pass through, blurring the line between neighborhood store and tourist storefront.

Reach them through the screen, not the cable box. About half have cut the cord, far above the national rate, so streaming and on-demand placement land where broadcast does not. Podcasts are a real channel here, with the share who never listen running well below typical, an open ear for audio that rewards sponsored and host-read formats.

They lean early on technology, adopting well ahead of the broad market, which makes new apps and devices an easier sell than usual. Social use tracks the national pattern, with Facebook still the largest single platform, so the edge is in format and timing rather than in any one unusual network.

Charlestonians buy often. Weekly purchasing runs well above the national pace and the truly rare shopper is uncommon, the cadence of a place where dining out and going out are woven into ordinary life. They also send a lot back: frequent returns happen at a much higher rate than typical, a sign of buyers who order freely and aren't shy about reversing a decision that misses.

Underneath the spending is real discipline. Aggressive savers outnumber the national share and non-savers come in below it, so the open wallet sits on a foundation that puts money away. Price still drives the final call about as often as anywhere, so frequency and discernment travel together rather than at odds.

This is the heart of the Charleston profile. Sleep is the loudest signal of all, with about 56% guarding it as a high priority, a discipline that anchors the rest of the routine. Health awareness sits far above the country, the obsessive tier alone running near triple the norm, and wellness is something they spend on rather than skip.

Openness about mental health is striking too. Only a small fraction keep it private, well under the national share, and a quarter actively advocate for it, the kind of posture that travels easily in a town with a major medical university shaping local attitudes toward care. Paddleboard culture and yoga studios meet a serious clinical influence here.
