Quaternary Geology

<div><a href='https://www.cteco.uconn.edu/guides/Quaternary_Geology.htm' rel='nofollow ugc' target='_blank'>See full Data Guide here. </a><br /></div>Quaternary Geology Feature Set is 1:24,000-scale data that illustrates the geologic features formed in Connecticut during the Quaternary Period, which spans from 2.588 ± 0.005 million years ago to the present and includes the Pleistocene (glacial) and Holocene (postglacial) Epochs. The Quaternary Period has been a time of development of many details of the Connecticut landscape and all surficial deposits. At least twice in the last Pleistocene, continental ice sheets swept across Connecticut from the north. Their effects are of pervasive importance to present-day occupants of the land.

The Quaternary Geology information illustrates the geologic history and the distribution of depositional environments during the emplacement of unconsolidated glacial and postglacial surficial deposits and the landforms resulting from those events in Connecticut. These deposits range from a few feet to several hundred feet in thickness, overlie the bedrock surface and underlie the organic soil layer of Connecticut. Quaternary Geology is mapped without regard for any organic soil layer that may overly the deposit.

For additional documentation including a description of the unconsolidated glacial and postglacial surficial deposits shown on the map, refer to the CT ECO Complete Resource Guide for Quaternary Geology.

The Connecticut Quaternary Geology information was initially compiled at 1:24,000 scale (1 inch = 2,000 feet) then recompiled for a statewide 1:125,000-scale map, Quaternary Geology Map of Connecticut and Long Island Sound Basin (PDF, 56 Mb) Stone, J.R., Schafer, J.P., London, E.H. and Thompson, W.B., 1992, U.S. Geological Survey Special Map, 2 sheets, scale 1:125,000, and pamphlet, 71 p. A companion map, the Surficial Materials Map of Connecticut (PDF, 26 Mb) Stone, J.R., Schafer, J.P., London, E.H., DiGiacomo-Cohen, M.L., Lewis, R.L., and Thompson, W.B., 2005, U.S. Geological Survey Scientific Investigation Map 2784, 2 sheets, scale 1:125,000, emphasizes the surface and subsurface texture (grain-size distribution) of these materials. The quaternary geology and surficial material features portrayed on these two maps are very closely related; each contributes to the interpretation of the other.

Mpox Vaccinations by Age Group

Data last updated 12/29/2022. Data are not currently being routinely updated. For more information about mpox, including vaccine eligibility criteria, see the DPH mpox webpage: ct.gov/dph/mpox.

Table published by the Connecticut Department of Public Health that contains the cumulative number of people by age group who have received at least one dose of JYNNEOS vaccine reported to CT WiZ (the Connecticut Immunization Information System). Age is age at the time of the first dose of monkeypox vaccine.

Currently vaccination is prioritized for individuals at the highest risk of exposure to someone with mpox. Since the size of this population is not known, the number vaccinated is reported without the vaccine coverage percentage. 

This table excludes residents of other states vaccinated in Connecticut. Connecticut residents vaccinated out of state are included if they were vaccinated in a jurisdiction that has established electronic vaccination data exchange with Connecticut (as of 8/31/2022, this is NYC, RI, NJ, DE, NV, Philadelphia).
Childhood Lead Poisoning: Prevalence by Town and Blood Lead Level Category

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 includes data on the prevalence by town and blood lead level category.
Juvenile Justice Policy and Oversight Committee Equity Metrics - Detentions

Connecticut's Juvenile Justice Policy and Oversight Committee (JJPOC) has developed this dataset and this dashboard to monitor and examine juvenile justice system involvement across the state for youth of different races, ethnicities, and genders.

The following metrics were chosen to understand key points in the juvenile justice system:

1. Delinquent referrals
2. Detentions
3. Non-judicial handling
4. Disposition of a first-time felony

Note: this dataset and the dashboard are being developed in phases, and at present they include data on Metric 1: Delinquent referrals, Metric 3: Detentions, and Metric 4: First-Time Felony Dispositions. Additional metrics will be added in the future.
Municipal Coronavirus Relief Fund (CRF) Expenditures by Town, March 1 - June 30, 2020

This dataset includes municipal reporting information for the Municipal Coronavirus Relief Fund (CRF) Program for Connecticut municipalities from March 1 - June 30, 2020. 

The CRF Program was established by the CT Office of Policy and Management (OPM) to reimburse municipalities for costs incurred in responding to the COVID-19 pandemic with funds from the Federal Coronavirus Aid, Relief, and Economic Security Act (CARES Act).

More information about the CRF Program can be found here: https://portal.ct.gov/OPM/Coronavirus/Coronavirus-Relief-Fund/Municipal-CRF-Program
Affordable Housing by Town 2011-2023

The Affordable Housing Appeals Procedure List is published annually on or about February 1. The data for the Affordable Housing Appeals Procedure List comes from different sources including federal, state and local programs. This makes it difficult to ensure complete accuracy, so DOH asks municipalities to provide a local administrative review of and input on the street addresses of units and projects as well as information on deed-restricted units. The responses received by DOH vary widely from each municipality.

In developing the Affordable Housing Appeals Procedure List, DOH counts:

-Assisted housing units or housing receiving financial assistance under any governmental program for the construction or substantial rehabilitation of low and moderate income housing that was occupied or under construction by the end date of the report period for compilation of a given year’s list; 
-Rental housing occupied by persons receiving rental assistance under C.G.S. Chapter 138a (State Rental Assistance/RAP) or Section 142f of Title 42 of the U.S. Code (Section 8); 
-Ownership housing or housing currently financed by the Connecticut Housing 
Finance Authority and/or the U.S. Department of Agriculture; and 
-Deed-restricted properties or properties with deeds containing covenants or restrictions that require such dwelling unit(s) be sold or rented at or below prices that will preserve the unit(s) as affordable housing as defined in C.G.S. Section 8-39a for persons or families whose incomes are less than or equal to 80% of the area median income.
Reunifications by SFY, DCF Office, Age at Exit and Length of Stay

This dataset contains aggregate data concerning the number of children that exited DCF care to be Reunified with a parent/guardian from whom they had been removed.  These figures are broken out by the DCF Region and Office responsible for the child's care, by their Age Group, and by whether they had been Reunified within 12 months of their entry to care or not.  It would be appropriate to roll up the data from all variables across multiple time periods, as they represent specific events in the lives of these children.  Please note that these figures do not represent unique children, and so should not be used as the basis for creating a rate based on the child population of the state.  These data form the basis of measurement for the Juan F. Consent Decree Exit Plan Outcome #7: Reunification Within 12 Months, although those figures are reported to the DCF Court Monitor on a quarterly rather than annual schedule.
2023 Disproportionately Impacted Areas

This dataset lists census tracts that are approved for identification as disproportionately impacted areas, according to Public Act 23-79, An Act Concerning Cannabis Regulation. 

"Disproportionately impacted area" means on and after August 1, 2023, a United States census tract in this state that has been identified by the Social Equity Council by using (1) a poverty rate metric and (2) ranking of historical conviction rates for drug-related 
offenses by census tract.

This list of disproportionately impacted areas is expected to be considered by the Social Equity Council at the August 1, 2023 meeting.
Utility Use and Cost Data for Executive Branch Agencies

This dataset summarizes the utility use and expenditures data for FY19 through FY24 for Executive Branch agencies. 

The data was pulled from the state's utility tracking system, EnergyCAP, on October 17, 2025, with the exception of the waste disposal data, which was pulled from Core-CT on August 2, 2025, the state's human resource management and financials system.

The data below may be incomplete and will be updated with more current data as it becomes available.

Shoreline Change Long Term

Shorelines are continuously moving in response to winds, waves, tides, sediment supply, changes in relative sea level, and human activities. Shoreline changes are generally not constant through time and frequently switch from negative (erosion) to positive (accretion) and vice versa. Cyclic and non-cyclic processes change the position of the shoreline over a variety of timescales, from the daily and seasonal effects of winds and waves, to changes in sea level over a century to thousands of years. The shoreline "rate of change" statistic thus reflects a cumulative summary of the processes that altered the shoreline for the time period analyzed.
DEEP Property

<div><a href='https://cteco.uconn.edu/guides/DEP_Property.htm' target='_blank' rel='nofollow ugc noopener noreferrer'>See full Data Guide here. </a><br /></div>DEEP Property is a polygon feature-based layer that includes all land owned in fee simple interest by the State of Connecticut Department of Energy and Environmental Protection. This layer is based on information that was collected and mapped at various scales and at different levels of accuracy. Generally, partial interests such as easements or development rights are not included in this layer. The exception is flood control areas, which may include permanent easements. Types of property in this layer include parks, forests, wildlife areas, flood control areas, scenic preserves, natural areas, historic reserves, DEEP owned waterbodies, water access sites and other miscellaneous properties. This layer is current and is updated as parcels are acquired by DEEP.
Trail Access

DEEP Trails Set:

Trail Access Points are point features in the Statewide Trails Database that describe where trails are accessed at trail heads, state and municipal parks and forests, or other points of departure. Trail Points of Interest are point features in the Statewide Trails Database that describe where there are scenic overlooks, bridges, river crossings or other historic or geologic sites of interest along trails. These features are directly located along trails and do not describe amenities commonly found on park grounds such as parking areas, picnic areas, and restrooms. Trail Point of Interest features are optional. Trails are line features in the Statewide Trails Database that describe the location of single and multi-use trails, access trails, connector trails, and regional trails. These features may also describe bike routes along public roads and their relationship with connecting multi-use paved trails used for walking, running, inline-skating, and bicyling, for example. Trail features describe hiking trails, nature trails, bike routes, and Americans with Disabilities Act (ADA) accessible trails such as certain walkways, boardwalks and stone dust surfaced trails. Individual trail features are described in terms of their surface type (unpaved, paved, unpaved road, paved road, etc.) and whether activities such as hiking, walking, running, inline skating, bicycling, mountain biking, motorbiking, all terraine vehicle use, snowmobiling, cross-country skiing, and horseback riding are permitted. Also indicates whether leashed or unleashed dogs are allowed. Roadway line features are optional features in the Statewide Trails Database used to place a trail system in context with nearby park roads or park entrance. They are very simple line features used to represent driveways, park roads, forest roads, and occasionally public roads on or along the public property where the trail system exists. Roadway line features are optional. They are not used for mapping bike routes. Trail line features are used for mapping bike routes.
