The Connecticut Health Bulletin (Conn Doc H342m) is a series of monthly publications published by Connecticut’s State Board of Health and later Connecticut’s Health Department. This publication changed content, publishing frequency, and volume numbering over the years.

June 1887 starts the series. The first issues were 4 pages containing a Monthly Mortality table, a brief remarks page and meteorological table for New Haven. January 1914 started a new format of 8 pages which included more vital statistics and health information paragraphs. This format allowed for flexibility in “publications of additional items to meet the steadily increasing interest of all classes of citizens in health problems.” In 1975 it went to bimonthly then in late 1980’s to quarterly and then to twice a year. 1990 is the last year the library received.

This finding aid lists article title, an author if included, and the publication  year and month/volume for each issue.

Census Tracts Identified for PA 23-205

This dataset lists census tracts that were identified as high poverty, low opportunity areas according to PA 23-205 Section 101.

"High poverty, low opportunity areas" mean a census tract in the state where thirty percent or more of the residents have incomes below the federal poverty level, according to the 2021 five-year United States Census Bureau American Community Survey.

The 2021 ACS estimates were used to identify these tracts.
State of CT: Open Expenditures - Ledger Archive

This archived data allows citizens to view who received payments from the State for goods or services and how much they received for historical fiscal years beginning in state fiscal year 2011-2012. The data can be explored by searching for specific payee names or by browsing by Government Function. The <a href = "https://opencheckbook.ct.gov" target ="_blank"> Open Checkbook app </a> allows the user to drill down from aggregated spending accounts all the way down to each individual payment to a payee for more recent fiscal years.

The actively updated, most recent seven fiscal years are available <a href = "https://data.ct.gov/Government/State-of-CT-Open-Expenditures-Ledger/jz5u-r6jf/about_data" target ="_blank"> here </a> 

This data is appended annually with an additional year of historical data.

Certain payee names have been removed in order to protect the privacy of individuals, in accordance with Health Insurance Portability and Accountability Act (HIPAA) regulations or where the information is otherwise protected by law. 

Redacted information includes:
•Payees who are statutorily protected
•Information that would lead to violating HIPAA laws
•Information of Minors
Licensed Automobile Dealers And Repairers

Listing of licensed automobile dealers and repairers, updated nightly.

Many Dealer and Repairer licenses are issued in a business name but the facility may be doing business in another name (have a DBA = Doing-Business-As). For example, XYZ Corporation may be doing business as Joe’s Garage. The address of Joe’s Garage will be on the list but the license will be in the XYZ Corporation name.
Municipal Spending Cap Report

This dataset includes municipal spending cap data used for the calculation of municipal revenue sharing grant amounts from 2018 through the most recent reporting year.

Subsection (f) of Connecticut General Statute Sec. 4-66l establishes a municipal expenditure cap that is the greater of the inflation rate or 2.5% or more of the prior fiscal year’s adopted budget expenditures, including expenditures from a municipality's general fund.

Municipalities that increase their adopted budget expenditures over the previous fiscal year by an amount that exceeds this cap receive a reduced revenue sharing grant. The reduction is equal to 50 cents for every dollar the municipality spends over the cap.

Municipalities must annually certify to the OPM secretary, on an OPM-prescribed form, whether they have exceeded the spending cap and, if so, by how much.

More information may be found here: https://www.cga.ct.gov/2024/sup/chap_050.htm#sec_4-66l

2020 U.S. Census Block Adjustments

This dataset lists the total population 18 years and older by census block in Connecticut before and after population adjustments were made pursuant to Public Act 21-13. PA 21-13 creates a process to adjust the U.S. Census Bureau population data  to allow for most individuals who are incarcerated to be counted at their address before incarceration. Prior to enactment of the act, these inmates were counted at their correctional facility address.

The act requires the CT Office of Policy and Management (OPM) to prepare and publish the adjusted and unadjusted data by July 1 in the year after the U.S. census is taken or 30 days after the U.S. Census Bureau’s publication of the state’s data. 

A report documenting the population adjustment process was prepared by a team at OPM composed of the Criminal Justice Policy and Planning Division (OPM CJPPD) and the Data and Policy Analytics (DAPA) unit. The report is available here: https://portal.ct.gov/-/media/OPM/CJPPD/CjAbout/SAC-Documents-from-2021-2022/PA21-13_OPM_Summary_Report_20210921.pdf

Note: On September 21, 2021, following the initial publication of the report, OPM and DOC revised the count of juveniles, reallocating 65 eighteen-year-old individuals who were incorrectly designated as being under age 18. After the DOC released the updated data to OPM, the report and this dataset were updated to reflect the revision.

Connecticut Airports

Airports Polygon is a 1:24,000-scale, feature-based layer that includes all airport features depicted on all of the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps that cover the State of Connecticut and are listed on the Federal Aviation Administration (FAA) "Airport Data (5010) & Contact Information" June 5, 2008 report.  Airports in New York, Massachusetts and Rhode Island that are near the Connecticut state boundary are included. Airports that are listed by FAA and are visible on aerial photography (Connecticut 2004 Orthophotos and Connecticut 2006 NAIP Color Orthophotos from National Agriculture Imagery Program) are included. Airports that are listed by FAA but are not visible on aerial photography are not included. All airports listed by FAA are included in a separate point feature-based layer, Airport FAA CT. The airport point locations were generated from latitude and longitude coordinates contained in the FAA report and all the attribute information in the report was included. The airport layer is based partly on information from USGS topographic quadrangle maps published between 1969 and 1984 which does not represent airports in Connecticut at any one particular point in time. The layer does depict current conditions as to airports listed by FAA and having location identification codes and visible on aerial photography of 2004 and 2006. The layer delineates airports and heliports. It includes airport name, airport location code, type of facility, public or private use of facility and state the airport is located in. It does not include airport elevation, flight schedule, runway capacity, or ownership information. Features are polygonal and generally depict landing strips and perimeters for large and small airports and helicopter landing pads. Attribute information allows to cartographic representation (symbolize) and labeling of these features on a map. This layer was originally published in 1994 and slightly updated in 2005.
Municipal Fiscal Indicators: Bond Ratings, 2019-2023

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.

A bond rating is an evaluation by credit-rating agencies of a municipality’s or school district’s credit risk. A municipality's or school district’s bonds may be rated by more than one rating agency. The three major rating agencies are Moody’s Investor Services, Standard and Poor’s Corporation, and Fitch Incorporated.

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 September 2025.

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