Fastest-growing counties in Delaware

Why do people move from one county or region to another? The usual suspects are jobs, family, significant others, and overall cost of living, but there are other elements at play. For those with children, moving within close proximity of a highly rated school district is a key contributing factor. For younger adults just starting out, living someplace with a vibrant social scene might be a top priority. And for those whose careers have wound down after a lifetime of work, finding retirement-friendly communities is the goal—communities deemed to be safe, offer accessibility to medical resources and leisure activities in equal measure, and be affordable for those on a limited income.

This is, of course, by no means an exhaustive list. People's reasons for choosing to live where they do are as diverse as people themselves.

As far as why certain counties across the U.S. have experienced growth, relocation is not the sole, or even primary, reason why. While more than 1,800 counties saw population gains in 2021, approximately 73% of all U.S. counties saw what the U.S. Census Bureau characterizes as a natural decrease. This was a significant jump from 2020, when 55.5% of countries experienced such a decrease. According to the Bureau, natural decrease is the simple result of "when there are more deaths than births in a population over a given time period." In 2021, the conflation of fewer births with an aging population that was also absorbing a higher-than-usual mortality rate due to the ongoing COVID-19 pandemic led to this "increased decrease."

Nonetheless, as stated 1,800 counties nationwide have grown larger over the last year, and a sizable percentage of them are in Delaware. Stacker compiled a list of the fastest-growing counties in Delaware using data from the U.S. Census Bureau.
