CONNECTICUT POPULATION CHANGE: 1990-2010

By: Kristen Miller, Legislative Analyst II

This report shows population changes in Connecticut and its municipalities in 1990, 2000, and 2010 using data from the United States censuses. It expresses the changes in both numeric and percentage format.

SUMMARY

From 1990 to 2010, Connecticut's population increased by 8.7%, from 3,287,116 to 3,574,097. Similarly, the majority of Connecticut's 169 municipalities increased in population during this time period.

Sterling grew by the greatest percentage, increasing its population by 62.5%. Seventeen municipalities increased in population by at least 30% (Andover, Burlington, Colchester, East Haddam, Eastford, Ellington, Hebron, Killingworth, Newtown, Oxford, Pomfret, Scotland, Sterling, Suffield, Tolland, Union, and Woodstock). Danbury gained the most people (15,308, a 23.3% increase).

Only 15 municipalities declined in population during this time period (Bristol, Enfield, Groton, Hartford, New Britain, New Haven, New London, Norfolk, Preston, Salisbury, Sharon, Sprague, Vernon, Washington, and Winchester). The decreases ranged from 0.3% in Bristol to 17% in Norfolk. Hartford lost the most people, 14,964. It should be noted that 11 of these 15 municipalities gained population from 2000 to 2010, but these gains were outweighed by population losses from 1990 to 2000.

Table 1 provides the population for Connecticut and its municipalities in 1990, 2000, and 2010 and the numeric and percent changes between these years. The data are from the U.S. Census Bureau and the Connecticut State Data Center.
