Been looking into where people are actually moving on the East Coast lately, and honestly some of these suburbs are growing like crazy. I stumbled on this study that breaks down the fastest-growing areas and what you'd actually need to earn to live comfortably there.

Some interesting patterns popped out. Fort Mill, South Carolina is up 77.6% in population - wild growth - and you're looking at needing around $121k annually to live there comfortably, though the median household income is actually slightly higher at $127k. Home values are sitting around $528k. Meanwhile, places like Waxhaw, North Carolina are even pricier - you'd need $134k to be comfortable there, with homes averaging over $604k.

If you're looking for great places to live that won't completely drain your wallet, some of the Florida suburbs show lower salary requirements. Union City, Georgia is one of the cheaper options at $86k needed annually with homes around $249k. Leesburg, Florida and Clayton, North Carolina also came in under $100k for comfortable living.

The data's based on 2023 populations between 20k-100k in metro areas with over 1 million people. They factored in cost of living indexes from groceries to transportation plus current home values from early 2025. So these great places to live are definitely attracting people - the population shifts from 2018 to 2023 show serious migration happening.

What's interesting is the gap between what you actually need and what people are earning. Some suburbs show household incomes below the comfortable living threshold, which probably explains why some areas are still more affordable options. If you're considering a move to one of these booming East Coast suburbs, the salary requirements vary pretty widely depending on which area appeals to you.
