Northeast Town Lines

Northeastern United States Town Boundary data are intended for geographic display of state, county and town (municipal) boundaries at statewide and regional levels. Use it to map and label towns 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.)
Prescription Monitoring Program: Average Days Supply and Daily Morphine Milligram Equivalent (MME)

This dataset shows the average days supply and daily morphine milligram equivalent (MME) of opioid prescription dispensed. The morphine milligram equivalent is an opioid dosage equivalent to morphine. This measurement is used to determine the abuse and overdose potential, and to set thresholds for prescribing and dispensing opioid pain relievers. The lowest effective dosage is set at less than 50 MME and the highest is greater than 90 MME.

COVID-19 Vaccinations in Nursing Homes by Facility - ARCHIVE

As of 6/1/2023, this data set is no longer being updated.

Connecticut nursing homes are required by the Centers for Medicare and Medicaid Services (CMS) to report on the impact of COVID-19 on their residents and staff through CDC’s National Healthcare Safety Network (NHSN). This reporting is intended to reflect recent COVID-19 activity in nursing homes.

Data presented here from NHSN reflect the percent of resident and staff that are up to date with COVID-19 vaccinations by Connecticut nursing homes. All nursing homes follow NHSN definitions and instructions when reporting to the NHSN COVID-19 module, ensuring data are reported in a systematic way. 

Per CDC, "Up to Date" is defined as having received all of the recommended COVID-19 vaccine doses.

Detailed information about COVID-19 reporting for nursing homes and NHSN can be found here: https://www.cdc.gov/nhsn/ltc/covid19/index.html
Index to Loyalist Connecticut Court Records, 1776-84

This index covers the years 1776-84 and references 867 individuals who were in some way charged as a Loyalist during the Revolutionary War.  These original documents are from various County & Superior Courts primarily from Fairfield, Hartford, Litchfield, New Haven, and New London Counties; Middlesex and Tolland Counties were created in 1785 and there is only 1 record from Windham County in the index.  Please keep in mind that this index is not comprehensive and additional information may be found within the un-separated files and records of each court. 

This index includes the surname and given name of the individual, residence, year of hearing, specific notes about the case, the Connecticut court where the case was heard along with drawer/box number where the original document is found.  The bulk of the documents are either warrants for an arrest or a personal or Grand Jury complaint registered against an individual. Notes include such bits of information such as the person’s rank, the reason for the charge, the verdict in the case, or a petition to reduce the sentence.  Of particular interest are three “Negro” men who were accused of treason, and accusations against several men who lived out of state but owned land in Connecticut.  Loyalism, not surprisingly, also seemed to run in families.

For more resources about Loyalists in Connecticut, please see our Loyalist Research Guide.

Combined Asthma Emergency Department and Hospitalizations by Census Tract, Town, Connecticut, 2010-2014

Note:  77% of overall reported events were geocoded by census tract level [ESRI ArcGIS], and the remaining 23% of events were equally weighted and redistributed proportionally within each town across the state. Therefore, all numbers and rates are estimates only, and reflect all asthma hospitalizations and ED visits that occurred in Connecticut from 2010-2014.
Rates based on counts fewer than 20 are unstable, and therefore are not presented; cells with less than 6 events are not displayed due to confidentiality regulations.
Impaired 2020 River, Lake, Estuary Set

<p><font size='2'>Connecticut 303(d) Impaired Waters 2020 is a subset of
Connecticut 305(b) Assessed Waters 2020. If any one of the assigned designated
uses is categorized as NOT Supporting, the assessed waterbody is included in
this subset and is considered impaired. Additional information about Integrated
Water Quality reporting is available on the CT DEEP website, <a href='https://portal.ct.gov/DEEP/Water/Water-Quality/Water-Quality-305b-Report-to-Congress' rel='nofollow ugc'>Integrated
Water Quality Report</a> page. </font></p>

<p><font size='2'>Connecticut 305(b) Assessed Waters files includes rivers,
lakes and estuaries that have been assessed in compliance with Sections 305(b)
and 303(d) of the federal Clean Water Act. Section 305(b) of the Clean Water
Act requires each state to monitor, assess and report on the quality of its
waters relative to attainment of designated uses established by the State's
water quality standards. Section 303(d) requires each State to compile a subset
of that list identifying only those waters not meeting water quality standards
and assign a Total Maximum Daily Load (TMDL) priority ranking to each impaired
waterbody.</font></p>

<p><font size='2'>This assessment is based on information collected and compiled
prior to 2020. It represents conditions at a particular point in time and does
not represent current conditions. Depending on the type of waterbody - river,
lake, or estuary - this information geographically displays attainment and
non-attainment (e.g. full supporting, not supporting, not assessed) for each
designated use - aquatic life, marine aquatic life, recreation use, fish
consumption, shellfish harvesting, and drinking water supply.</font></p>

Shoreline Change Transects 1983-2006

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.
ARCHIVE: Municipal Fiscal Indicators: Benchmark Labor Data, 2020

Note: Municipal fiscal indicators data for single years has been consolidated into multi-year datasets. The new dataset is available here: https://data.ct.gov/d/5ijb-j6bn

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 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 2016-2020 published in July 2022.

Data on the 2020 Municipal Fiscal Indicators is included in the following datasets:

1. <a href="https://data.ct.gov/d/aiwt-8yhn">Municipal Fiscal Indicators, 2020</a>
2. <a href="https://data.ct.gov/d/wb9r-t4hp">Municipal Fiscal Indicators: Uniform Chart of Accounts - Expenditures by Town, 2020</a>

Alternative Groundwater Protection Criteria Area (GWPC)

The Alternative GWPC layer is to be used when evaluating the Alternative GWPC provision, section 22a-133k-3(d)(2) of the RSRs, amended on February 16, 2021.   This layer represents the GA groundwater classification area where an Alternative GWPC could be eligible if a groundwater plume is located in the designated Alternative Groundwater Protection Criteria area and all other requirements of 22a-133k-3(d)(2) have been satisfied.   The layer provides more flexibility in achieving groundwater compliance in areas with no current or future drinking water use.
Prescription Monitoring Program: Prescription Dispensations

This dataset provides the prescription count for controlled substances, non-controlled substances, opioids, benzodiazepine, stimulant, gabapentin, & naloxone dispensations in the state. It only includes dispensations to CT residents reported to the CT Prescription Monitoring & Reporting System (CPMRS). 

Controlled substances are those that have been categorized as schedule II - V.

Opioid Agonists are generally used to treat moderate to severe pain typically associated with injury, surgery, or various health conditions.

Opioid partial agonists bind to opioid receptor sites and works slowly in the body to help prevent withdrawals and reduce cravings for opioid drugs. Opiate partial agonists are used to treat opioid use disorder. Prescription opioid partial agonists include buprenorphine, butorphanol, and pentazocine.

Benzodiazepines slow down the central nervous system, and often used to relieve anxiety and muscle spasms, as well as reduce seizures.

Stimulants increase alertness and energy, enhancing focus. Stimulants are commonly used to treat attention-deficit hyperactivity disorders (ADHD).

Gabapentin is an anticonvulsant or antiepileptic drug, used to treat seizures and relieve pain.

Naloxone is used to quickly reverse an opioid overdose. Naloxone is an opioid antagonist, and works by attaching to opioid receptors, to reverse and block the effects of other opioids.

Quaternary Geology Line Features

<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.
School Attendance by District, 2021-2022

This dataset includes the attendance rate for public school students PK-12 by district during the 2021-2022 school year.

Attendance rates are provided for each district for the overall student population and for the high needs student population. Students who are considered high needs include students who are English language learners, who receive special education, or who qualify for free and reduced lunch.

When no attendance data is displayed in a cell, data have been suppressed to safeguard student confidentiality, or to ensure that statistics based on a very small sample size are not interpreted as equally representative as those based on a sufficiently larger sample size.

Positive Net Shoreline Movement (meters)

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.
Qualified Census Tracts Data

For administration of the American Rescue Plan (ARP), the Office of Policy and Management (OPM) is providing access to data on Qualified Census Tracts (QCTs) in Connecticut.
As part of guidance for implementation of the ARP, Treasury identified QCTs as "a common, readily-accessible, and geographically granular method of identifying communities with a large proportion of low-income residents. Using an existing measure may speed implementation and decrease administrative burden, while identifying areas of need at a highly-localized level."
Estimates of Statutory Aid to Municipalities

Pursuant to C.G.S. section 4-71b, the Office of Policy and Management annually posts estimated grant amounts for certain ongoing grant programs under which the State of Connecticut’s payments to municipalities are determined by statutory formulas or payment lists.

This dataset contains estimated grant payments for fiscal year 2025 and projected grant payments for fiscal years 2026 and 2027 under current enacted law. Audit adjustments, timing of payments, application of statutory penalties, revised grant calculations, or the receipt of more current data can materially impact actual payments. In particular, many values shown for FY 2027 are based on current data and will be updated once new data becomes available.

This dataset does not include payments to municipalities from Federal funds under the American Rescue Plan Act (ARPA). The current table of ARPA allocations can be found in Public Act 24-81, which includes amendments made to prior versions of the allocation table in PA 21-2, JSS, PA 22-118, PA 22-146, and PA 23-204.

October 2025 update: Values for Tiered PILOT in FY 2026 and FY 2027 have been updated with more accurate information. Estimates for all other grant programs remain unchanged from prior publication.
