CT DPH COVID -19 Race and Ethnicity Data Summary

This report summarizes data on COVID-19 cases and COVID-19 associated deaths by race/ethnicity for the state of Connecticut and the 10 largest Connecticut towns. Data on race/ethnicity are missing on almost half (47%) of reported COVID-19 cases. CT DPH has urged healthcare providers and laboratories to complete information on race/ethnicity for all COVID-19 cases. 

All data in this report are preliminary; data will be updated as new COVID-19 case reports are received and data errors are corrected. Data on COVID-19 cases and COVID-19-associated deaths were last updated on April 20, 2020 at 3 PM. Information about race and ethnicity are collected on the Connecticut Department of Public Health (DPH) COVID-19 case report form, which is completed by healthcare providers for laboratory-confirmed COVID-19 cases. Information about the race/ethnicity of COVID-19-associated deaths also are collected by the Connecticut Office of the Chief Medical Examiner and shared with DPH. Race/ethnicity categories used in this report are mutually exclusive. People answering ‘yes’ to more than one race category are counted as ‘other’.
Disproportionately Impacted Areas, Identified for Public Act 21-1, An Act Concerning Responsible and Equitable Regulation of Adult-Use Cannabis

Public Act 21-1, An Act Concerning Responsible and Equitable Regulation of Adult-Use Cannabis, legalized the adult use of cannabis in Connecticut. The bill established a Social Equity Council, which will promote and encourage the full participation in the cannabis industry by people from communities disproportionately harmed by cannabis prohibition. The bill targets its equity measures at "disproportionately impacted areas" (or DIAs), census tracts in the state that meet certain statistical thresholds, as determined annually by the Social Equity Council.
Prescription Monitoring Program: Schedule II Drug Prescriptions Dispensed

This dataset includes the amount of Schedule II prescription drugs dispensed over a 3-month span. On the controlled substance Schedule II-V; Schedule II prescription drugs have a high potential for abuse, potentially leading to severe psychological or physical dependence. Schedule II drugs are narcotic pain medications and stimulants. This only includes dispensations to CT residents reported to the CT Prescription Monitoring & Reporting System (CPMRS).

*Please note that although medical marijuana is a schedule II drug in CT, these dispensations will be reported out separately.*
Executive Branch Artificial Intelligence System Inventory

Public Act No. 23-16, Section 1, effective July 1, 2023, directs the Department of Administrative Services to conduct an annual inventory of all systems that employ artificial intelligence and are used by any state agency.

The public act defines artificial intelligence as (A) an artificial system that (i) performs tasks under varying and unpredictable circumstances without significant human oversight or can learn from experience and improve such performance when exposed to data sets, (ii) is developed in any context, including, but not limited to, software or physical hardware, and solves tasks requiring human-like perception, cognition, planning, learning, communication or physical action, or (iii) is designed to (I) think or act like a human, including, but not limited to, a cognitive architecture or neural network, or (II) act rationally, including, but not limited to, an intelligent software agent or embodied robot that achieves goals using perception, planning, reasoning, learning, communication, decision-making or action, or (B) a set of techniques, including, but not limited to, machine learning, that is designed to approximate a cognitive task.
COVID-19 Cases in CT Schools by County, 2020-2021 School Year - Archive

Counts of COVID-19 Cases in CT Schools by County

As of 6/24/2021, COVID-19 school-based surveillance activities for the 2020 – 2021 academic year has ended. The Connecticut Department of Public Health along with the Connecticut State Department of Education are planning to resume these activities at the start of the 2021 – 2022 academic year.
Discharged Children With Permanency Maintained 12 Months:  Annual Trend By Age Group

This dataset contains aggregate data concerning the number of child placement episodes that ended with a legal discharge from DCF care, and for whom the end of a 12 month observation period (starting with their legal discharge date) terminated during the SFY.  These figures are broken out by the DCF Region and Office responsible for the child's care, by their Age Group, and by whether another placement episode for that child began within 12 months of their discharge from 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.  These data form the basis of measurement for the Juan F. Consent Decree Exit Plan Outcome #11: Permanency Maintained (No Re-Entry), although those figures are reported to the DCF Court Monitor on a quarterly rather than annual schedule.
ARCHIVED - CT DPH Influenza and COVID-19 Syndromic Surveillance by Week

Syndromic surveillance provides public health officials with a timely system for detecting, understanding, and monitoring health events. By tracking symptoms of patients in emergency departments—before a diagnosis is confirmed—public health can detect unusual levels of illness.

Syndromic data can serve as an early warning system for public health concerns such as influenza and COVID-19 outbreaks.  

These data represent the percent of emergency department and urgent care visits related to Influenza Like Illness or COVID Like Illness.  

Additional Syndromic Surveillance information can be found at https://www.cdc.gov/nssp/overview.html.

Shoreline Change Short 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.

Connecticut Quasi-Public Organizations Checkbook and Payroll Data

This site is maintained by the Connecticut Data Collaborative and provides access to checkbook and payroll information of quasi-public organizations in Connecticut. The data are updated yearly.

Quasi-public agencies are independent government corporations that are created through legislation to perform a particular service or set of public functions. Most quasi-public agencies depend primarily on sources of revenue associated with the services they provide. In Connecticut, quasi-public agencies are required to submit annual reports to the legislature, including a summary of their activities and financial information.

In addition, quasi-public agencies are required to submit financial and personnel information to the comptroller's office which is uploaded to this application as part of the OpenConnecticut government transparency initiative.

To learn more about a specific quasi-public agency, please visit their website.

Regional Performance Incentive Program Grants

The Regional Performance Incentive Program was established in 2007 to encourage municipalities to participate in voluntary intermunicipal or regional shared services projects that have the potential to produce measurable “economies of scale,” provide desired or required public services, and lower the costs and tax burdens associated with the provision of such services. The Office of Policy and Management administers these grants which are open to Councils of Governments (COGs) or Regional Educational Service Centers (RESCs), in accordance with <a href="https://cga.ct.gov/current/pub/chap_050.htm#sec_4-124s">Connecticut General Statutes Section 4-124s</a>.

The dataset lists grant awards from 2022 to present. More information on older awards can be found at: <a href="https://portal.ct.gov/opm/igpp/grants/regional-performance-incentive-program/regional-performance-incentive-program">Regional Performance Incentive Program</a>.
Erosion Susceptibility Sites

Connecticut Erosion Susceptibility a 1:24,000-scale, polygon feature-based layer that was developed as a predictive tool to show areas most susceptible to terrace escarpment type erosion. The layer compiled from the soils and quaternary geology data layers and was field tested during October-December, 2005. The Erosion Susceptilibity layer was developed as part of Project #03-02 Statewide GIS Analysis and Mapping of the Geologic Conditions Contributing to Eroding Terrace Escarpments. The layer does not represent eroding conditions at any one particular point in time, but rather base or general conditions which can be accounted for during planning or management strategies. The layer includes 4 types of areas susceptible to erosion, ranked 1 (most susceptible) through 4, and their descriptive attribute. Areas outside of the mapped polygons can be considered less susceptible to erosion. Data is compiled at 1:24,000 scale. This data is not updated.

Connecticut Erosion Sites is a site specific, point feature-based layer developed at 1:24,000-scale that includes decriptive information regarding the character of the erosion (severity, slope, geologic factors) at selected locations through out the state. The layer is based on information collected and compiled during October-December, 2005 while field testing the applicability of the Erosion Susceptilibity layer developed as part of Project #03-02 Statewide GIS Analysis and Mapping of the Geologic Conditions Contributing to Eroding Terrace Escarpments. The layer represents conditions at a particular point in time. The layer includes 83 locations and descriptive attributes (site name, severity of erosion, description, etc) as well as attributes from a spatial join with merged soils and quaternary geology layers. Features are point locations that represent the selected study areas within the state; it is NOT a comprehensive inventory of erosion locations. Data is compiled at 1:24,000 scale. This data is not updated.
