No other originally reported amounts were effected.  Corrected amounts are shown here.
Regional Councils of Governments Boundaries

Connecticut’s planning regions provide a geographic framework within which municipalities can jointly address common interests, and coordinate such interests with state plans and programs.  State statutes authorize the secretary of the Office of Policy and Management (OPM) to designate or redesignate the boundaries of logical planning regions, whereas the member municipalities of each planning region are authorized under separate state statutes to establish a formal governance structure known as a regional council of governments (RCOG).

The Office of Policy and Management (OPM) recently completed a comprehensive analysis of the boundaries of logical planning regions in Connecticut under Section 16a-4c of the Connecticut General Statutes (2014 Supplement).  This analysis resulted in the number of planning regions being reduced from the original fifteen (15) to nine (9), as a result of four (4) voluntary consolidations and the elimination of two (2) planning regions.
COVID-19 Town Level Data - Archive

Town Level COVID-19 Data

As of 6/1/2023, this data set is no longer being updated.

The COVID-19 Data Report is posted on the Open Data Portal every day at 3pm. The report uses data from multiple sources, including external partners; if data from external partners are not received by 3pm, they are not available for inclusion in the report and will not be displayed. Data that are received after 3pm will still be incorporated and published in the next report update.

Suppression:   the data in towns with fewer than five (5) cases or five (5) positive NAAT tests in the past seven (7) days are suppressed.

The cumulative number of COVID-19 cases (cumulative_cases) includes all cases of COVID-19 that have ever been reported to DPH.  The cumulative number of COVID_19 cases in the last 7 days (cases_7days) only includes cases where the specimen collection date is within the past 7 days.  While most cases are reported to DPH within 48 hours of specimen collection, there are a small number of cases that routinely are delayed, and will have specimen collection dates that fall outside of the rolling 7 day reporting window.  Additionally, reporting entities may submit correction files to contribute historic data during initial onboarding or to address data quality issues; while this is rare, these correction files may cause a large amount of data from outside of the current reporting window to be uploaded in a single day; this would result in the change in cumulative_cases being much larger than the value of cases_7days.

On June 4, 2020, the US Department of Health and Human Services issued guidance requiring the reporting of positive and negative test results for SARS-CoV-2; this guidance expired with the end of the federal PHE on 5/11/2023, and negative SARS-CoV-2 results were removed from the List of Reportable Laboratory Findings. DPH will no longer be reporting metrics that were dependent on the collection of negative test results, specifically total tests performed or percent positivity.  Positive antigen and PCR/NAAT results will continue to be reportable.
CT DCF Area Boundaries

<div style='text-align:Left;font-size:12pt'><p><span>This is a boundary file showing the catchment area for which each of the 14 DCF Area Offices is responsible. Catchment areas are comprised of complete Towns, but not necessarily complete Zip Codes. Data is as of 7/1/2014, is unlikely to change frequently, and will be updated only as changes are made to the catchment areas.</span></p></div>
CT Vicinity County Polygon

Connecticut and Vicinity County Boundary data are intended for geographic display of state and county boundaries at statewide and regional levels. Use it to map and label counties on a map. These data are derived from Northeastern United States Political Boundary Master layer.
This information should be displayed and analyzed at scales appropriate for 1:24,000-scale data. The State of Connecticut, Department of Environmental Protection (CTDEP) assembled this regional data layer using data from other states in order to create a single, seamless representation of political boundaries within the vicinity of Connecticut that could be easily incorporated into mapping applications as background information. More accurate and up-to-date information may be available from individual State government Geographic Information System (GIS) offices. Not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)
Assets retired from data.ct.gov

Dataset of assets that have been retired or that are currently being retired from data.ct.gov. Datasets may be retired for a number of reasons, including age, factual inaccuracies, low usage, and/or replacement by another asset.

Wellhead Protection Areas - Adjacent State

See full Data Guide here. Aquifer Protection Areas Set is a 1:24,000-scale, polygon feature-based layer that includes all Preliminary (Level B) and Final (Level A) Aquifer Protection Areas approved by the Connecticut Department of Energy and Environmental Protection (DEEP). These areas represent the land area contributing ground water to active public water supply wells or well fields that serve more than 1000 people that are set in sand and gravel aquifers (stratified drift deposits). These areas are commonly referred to as wellhead protection areas. The Aquifer Protection Areas were delineated by the individual water utilities owning the well fields and submitted to the DEEP for approval. The preliminary mapping provides a general estimate of the area contributing ground water to the well field. The final mapping is based on extensive, site-specific, detailed modeling of the ground water flow system. As the final mapping is completed it replaces the preliminary mapping. The layer is based on information collected and compiled from 1991 to the present. The layer depicts current conditions. Attribute information is comprised of codes to uniquely identify individual features, encode the aquifer protection area type and status, and cartographically represent area features on a map. Data is compiled at 1:24,000 scale. This data is updated as final mapping becomes available.
Underground Storage Tanks (USTs) - Contact Details

This list provides Underground Storage Tank (UST) site, tank, contact and Enforcement information for the approximately 45,000 commercial underground storage tanks (USTs) previously and currently registered in Connecticut, of which about 8,000 are still in use. (There are 3 other related data sets:1- Facility and Tank Details, 2-Enforcement Summary, and 3-Compliance Details.)

Annually, or when a UST is installed, removed, or altered, a notification form must be completed via EZFile (see link) and submitted to CT DEEP.  Notification is required for non-residential underground storage tanks, including those for oil, petroleum and chemical liquids, as well as residential home heating oil tanks serving five or more units.  See online at: https://www.ct.gov/deep/cwp/view.asp?q=322600

The underground storage tank regulations (see link) and the Connecticut underground storage tank enforcement program have been in effect since November 1985.  This list is based on notification information submitted by the public since 1985, and is updated weekly.  This list contains information on both active and on non-active USTs, as well as federally regulated and state regulated USTs.

Factors to Consider When Using this data:

-Not every required notification form is submitted to the DEEP.  We can only enter the information we receive.

-We know there are errors in the data although we strive to minimize them.  Error examples may include: notification forms completed incorrectly by the owner/operator, data entry errors, duplicate site information, misspelled names and addresses and/or missing data.
Municipal Fiscal Indicators: Type and Number of Pension Plans, 2020-2023

Municipal Fiscal Indicators is an annual compendium of information compiled by the Office of Policy and Management, Office of Finance, Municipal Finance Services Unit (MFS). Municipal Fiscal Indicators contains the most current financial data available for each of Connecticut's 169 municipalities.

The data contained in Indicators provides key financial and demographic information on municipalities in Connecticut. The data includes selected demographic and economic data relating to, or having an impact upon, a municipality’s financial condition.

The majority of this data was compiled from the audited financial statements that are filed annually with the State of Connecticut, Office of Policy and Management, Office of Finance. Unlike prior years' where the audited financial information was compiled by OPM, the FY 2020 and beyond information in this edition was based upon the self-reporting by municipalities of their own audited data.

The most recent edition is for the Fiscal Years Ended 2019-2023 published in July 2025.

The most recent data on the Municipal Fiscal Indicators is included in the following datasets:

Liquor Control Suspensions

Establishments that have been suspended by the Liquor Control Commission.  The Liquor Control Commission may impose fines on permittees and suspend or revoke liquor permits in connection with violations of Connecticut liquor control statutes or regulations. The establishments in this dataset were suspended after either: (1) a formal hearing in which the Liquor Control Commission found a violation of state liquor laws, or (2) entering into a voluntary agreement to settle allegations without a finding of fault.
COVID-19 Cases in Child Care Centers and Group Child Care Homes by Week - Archive

This dataset summarizes the number of cases among child care attendees and staff reported to the Department of Public Health (DPH). 

Each week, licensed child care centers are required to report cases of COVID-19 among attendees and staff to the DPH and the local health department. There are 1,388 licensed child care centers and group child care homes in Connecticut that serve approximately 50,000 children. 

Beginning the week of January 9th, reporting transitioned from individual case reporting to aggregate reporting of cases among attendees and staff. The form for collecting aggregate data from child care centers can be found here: https://forms.office.com/pages/responsepage.aspx?id=-nyLEd2juUiwJjH_abtzi-XnLB2c4-RLhUuoE9uLWJJUNURSR09GNlBBWFVIMlFaQ1BGUzcxMFNDUy4u

Data are preliminary and, like other passive surveillance systems, under reporting occurs and the true incidence of disease is more than the number of cases reported. Data from previous weeks are updated as new data are received. Several weeks of data from the new reporting system will be needed to determine trends.

Childhood Lead Poisoning: Incidence by Race/Ethnicity

As of January 1, 2009, Connecticut law mandates that medical providers must conduct annual lead screening (i.e., blood lead testing) for each child 9 to 35 months of age. Furthermore, the law requires that any child between 36-72 months of age who has not been previously tested must also be tested by the child’s medical provider, regardless of risk. 

This dataset shows the incidence of childhood lead poisoning by race/ethnicity. 

Incidence = Number of new cases
Incidence % = Number of new cases / Population screened with no history of elevated level
