Population Growth Through 2025 Driven by New Haven, Hartford, Fairfield Counties

Connecticut’s population, which was just under 3.3 million in 1990 and just over 3.5 million two decades later, is projected to exceed 3.7 million by 2025, according to Connecticut Population Projections featured on the University of Connecticut’s Connecticut State Data Center website. The interactive site provides a breakdown of projections for each of the state’s eight counties – and all are expected to grow during the next dozen years.  The most dramatic growth is anticipated in New Haven County, which is seen to exceed 900,000 residents for the first time by 2025.  The state population is predicted to increase by slightly more than 100,000 residents between 2015 and 2025.

Overall, the state’s population is expected to reach 3.66 million by 2015 and grow to 3.74 million by 2025.  Litchfield County will likely see the slowest growth, with less than an additional 1,000 residents anticipated over the decade.  Middlesex County is expected to grow by about 2,000 residents; Tolland County by nearly 5,000.  Windham County is expected to grow at twice the rate of New London County, as both are anticipating adding between 6,000 and 7,000 residents, although New London County has more than twice the population.

Here’s the breakdown by county of the projections:

The Connecticut State Data Center provides population projections to assist state agencies, non-profit organizations, businesses, governments, and centers/organizations to identify potential population changes into the future. These projections are created based upon several datasets and while these estimates are developed based on multiple data sources, actual population changes may vary from these projections.
