Connecticut Mainland Polygon

Connecticut Mainland Line includes the line features of a layer named Connecticut Mainland. Connecticut Mainland is a 1:24,000-scale, polygon and line feature-based layer that depicts the geographic area encompassed by and the boundary for the State of Connecticut with an additional linear shoreline feature separating the Connecticut mainland from the waters of Long Island Sound. The layer includes a polygon feature representing the Connecticut mainland, a polygon feature representing Connecticut waters in Long Island Sound and approximately 700 polygon features representing Connecticut islands in Long Island Sound. The layer is based on information from USGS topographic quadrangle maps published between 1969 and 1984 and latitude and longitude coordinates that define the boundary between the states of Connecticut and New York in Long Island Sound. Feature length and geographic area are encoded for linear and polygon features, respectively. This layer was originally published in 2005.

The most recent edition is for the Fiscal Years Ended 2008-2012 published in December of 2012
Hazardous Waste Manifest Data (CT) 1984 – 2008

NOTES:   
1.  Please use this link to leave the data view to see the full description: https://data.ct.gov/Environment-and-Natural-Resources/Hazardous-Waste-Manifest-Data-CT-1984-2008/h6d8-qiar
2. Please Use ALL CAPS when searching using the "Filter" function on text such as: LITCHFIELD. But not needed for the upper right corner "Find in this Dataset" search where for example "Litchfield" can be used.

Dataset Description:
We know there are errors in the data although we strive to minimize them.  Examples include:
•         Manifests completed incorrectly by the generator or the transporter - data was entered based on the incorrect information. We can only enter the information we receive.
•         Data entry errors – we now have QA/QC procedures in place to prevent or catch and fix a lot of these.
•         Historically there are multiple records of the same generator.  Each variation in spelling in name or address generated a separate handler record.  We have worked to minimize these but many remain.  The good news is that as long as they all have the same EPA ID they will all show up in your search results.
•         Handlers provide erroneous data to obtain an EPA ID - data entry was based on erroneous information.  Examples include incorrect or bogus addresses and names. There are also a lot of MISSPELLED NAMES AND ADDRESSES!
•         Missing manifests – Not every required manifest gets submitted to DEEP. Also, of the more than 100,000 paper manifests we receive each year, some were incorrectly handled and never entered.
•         Missing data – we know that the records for approximately 25 boxes of manifests, mostly prior to 1985 were lost from the database in the 1980’s. 
•         Translation errors – the data has been migrated to newer data platforms numerous times, and each time there have been errors and data losses.
•         Wastes incorrectly entered – mostly due to complex names that were difficult to spell, or typos in quantities or units of measure.

Since Summer 2019, scanned images of manifest hardcopies may be viewed at the DEEP Document Online Search Portal:  https://filings.deep.ct.gov/DEEPDocumentSearchPortal/
Regional Service Sharing Grants to Councils of Governments

Pursuant to Connecticut General Statutes Sections <a hfref="https://cga.ct.gov/current/pub/chap_050.htm#sec_4-66r">4-66r</a> and <a hfref="https://cga.ct.gov/current/pub/chap_050.htm#sec_4-66k">4-66k</a>, the Office of Policy and Management distributes regional services grants (RSG) to councils of governments (COGS) from the regional performance incentive account. The Secretary approves the spending plan for each COG before an RSG award is executed. Allowable spending categories include: comprehensive planning, regional services and municipal technical support.

Statutes dictate the distribution formula which has changed over time. The data set lists awards to COGs from 2014 through present.

Next Generation Accountability System

Connecticut’s Next Generation Accountability System is a broad set of 12 indicators that help tell the story of how well a school is preparing its students for success in college, careers and life. The system moves beyond test scores and graduation rates to provide a more holistic, multi-factor perspective of district and school performance.

The 12 Indicators are:
1. Academic achievement status measured by state assessments
2. Academic growth
3. Assessment participation rate
4. Chronic absenteeism
5. Postsecondary preparation - coursework
6. Postsecondary readiness – exams and college credit
7. Graduation – on track in ninth grade
8. Graduation – four-year adjusted cohort graduation rate – all students
9. Graduation – six-year adjusted cohort graduation rate – high needs
10. Postsecondary entrance rate – all students (college enrollment)
11. Physical fitness
12. Arts access

Disconnected Youth in Connecticut

In May 2024, the Connecticut General Assembly passed Public Act No. 24-45 (PA 24-45), which mandates that the Connecticut Preschool Through Twenty Workforce Information Network (P20 WIN) Executive Board disseminate a report on disconnected youth on an annual basis, starting in 2025. The Disconnected and At-Risk Youth in Connecticut report examines several socioeconomic, demographic, and other factors associated with disconnection to inform stakeholders seeking to identify subpopulations to target efforts to reconnect  and/or prevent disconnection for young people ages 14-26.
CT Vicinity State Lines

Connecticut and Vicinity State Boundary data are intended for geographic display of state boundaries at statewide and regional levels. Use it to map and label states 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.)
