Learn moreCharleston International Airport: a real, in-town advantage
Charleston International Airport sits within North Charleston city limits, recording a record 6.34 million passengers in 2025 -- a genuine, direct advantage unique to North Charleston among the markets built in this dataset, none of which host their own commercial airport.
I-26 corridor congestion is real, but commute times are genuinely shorter than from Mount Pleasant or Summerville
The North Charleston-to-downtown I-26 stretch is described in Post and Courier editorial coverage as one of the most congested corridors in the state; commute times run as short as 15-20 minutes off-peak but extend to 30-45 minutes, and up to an hour with incidents, during peak periods -- genuinely shorter than Summerville's 45-70 minute peak commute or Mount Pleasant's own bridge-dependent commute, both cited elsewhere in this dataset.
Modest CARTA transit access
CARTA, the region's primary bus system, including the Route 10 Rivers Avenue Express connecting North Charleston to downtown, carried 2,513,400 riders in 2025 (roughly 9,700 per weekday as of Q4 2025) -- real but modest ridership relative to the metro's population.
