An interactive data map on the Connecticut Data Collaborative website enables the public to research and review the population trends from the most recent census, and its predecessor in 2010. The data map can be seen at www.ctdata.org/census-2020-explorer-page . Available data includes an array of additional demographics, by city and town.
“Making data accessible and sharing data on the diversity of our residents is an essential element in better understanding our state,” explained Michelle Riordan-Nold, Executive Director of the CT Data Collaborative. “As Connecticut’s population continues to evolve, having the data is important for decision-making.”
Among communities with more than 1,000 residents of Asian/Pacific heritage as of the 2020 Census, those with the greatest percentage increase in the previous decade are Ellington (+142%), south Windsor (+138%), Rocky Hill (+106%), and Avon (+103%).
The 2020 Census also indicated that Connecticut’s Latino or Hispanic population grew by 30.1% to 623,293; Black population increased by 7.7% to 360,937; and population of White residents dropped by 10.5% to 2,279,232.
Asian/Pacific encompasses all of the Asian continent and the Pacific islands of Melanesia (New Guinea, New Caledonia, Vanuatu, Fiji and the Solomon Islands), Micronesia (Marianas, Guam, Wake Island, Palau, Marshall Islands, Kiribati, Nauru and the Federated States of Micronesia) and Polynesia (New Zealand, Hawaiian Islands, Rotuma, Midway Islands, Samoa, American Samoa, Tonga, Tuvalu, Cook Islands, French Polynesia and Easter Island). As with most commemorative months, Asian/Pacific American Heritage Month originated with Congress, three decades ago.
