A listing of Census Tracts including the names of towns in which they fall for CT. In 2010, the Census tract data no longer contained information necessary to associate tracts with towns (Minor Civil Division in Census terms). This file was generated to allow data users in CT to summarize census data to the town level in Connecticut

Population by town in Connecticut based on the 2010 census

Census tracts nominated by Governor Malloy as Opportunity Zones. Qualified census tracts are those that have a poverty rate of at least 20 percent of a median income that does not exceed 80 percent of the area median income. The opportunity fund model encourages investors to pool their resources in opportunity zones, increasing the scale of investments going to underserved areas. The program provides a federal tax incentive for investors to re-invest unrealized capital gains into opportunity zones through opportunity funds. Under the terms of the program, the governor of each state must submit a plan to the federal government designating up to 25 percent of the qualified census tracts in their state as opportunity zones, which is then subject to approval of the Secretary of the Treasury.

2010 Census 5-Digit ZIP Code Tabulation Area (ZCTA5) State-based. ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data from Census.

The Census Planning Database is produced by the U.S. Census Bureau. It assembles a range of housing, demographic, socioeconomic, and census operational data that can be used for survey and census planning.

The Planning Database uses selected Census and selected 2012-2016 American Community Survey (ACS) estimates. In addition to variables extracted from the census and ACS databases, operational variables include the 2010 Census Mail Return Rate for each block group and tract.

This dataset is a subset of the 2018 Census Planning Database, filtered for the state of Connecticut, and including calculated percentages for a variety of variables. Variables relating to geography, population, households, housing units, census operations, and hard to count populations at the tract and block level can also be found on the CT Data Portal with the tag "Census 2020."
