Land Area

Water Area

Land area is a measurement providing the size, in square miles, of the land portions of geographic entities for which the Census Bureau tabulates and disseminates data. Area is calculated from the specific boundary recorded for each entity in the Census Bureau's geographic database. Land area is based on current information in the TIGER® data base, calculated for use with Census 2010.

Water Area figures include inland, coastal, Great Lakes, and territorial sea water. Inland water consists of any lake, reservoir, pond, or similar body of water that is recorded in the Census Bureau's geographic database. It also includes any river, creek, canal, stream, or similar feature that is recorded in that database as a two- dimensional feature (rather than as a single line). The portions of the oceans and related large embayments (such as Chesapeake Bay and Puget Sound), the Gulf of Mexico, and the Caribbean Sea that belong to the United States and its territories are classified as coastal and territorial waters; the Great Lakes are treated as a separate water entity. Rivers and bays that empty into these bodies of water are treated as inland water from the point beyond which they are narrower than 1 nautical mile across. Identification of land and inland, coastal, territorial, and Great Lakes waters is for data presentation purposes only and does not necessarily reflect their legal definitions.

    CT School Learning Model Indicators by County (14-day metrics) - ARCHIVE

    data.ct.gov | Last Updated 2023-08-07T19:50:49.000Z

    NOTE: This dataset pertains only to the 2020-2021 school year and is no longer being updated. For additional data on COVID-19, visit data.ct.gov/coronavirus. This dataset includes the leading and secondary metrics identified by the Connecticut Department of Health (DPH) and the Department of Education (CSDE) to support local district decision-making on the level of in-person, hybrid (blended), and remote learning model for Pre K-12 education. Data represent daily averages for two-week periods by date of specimen collection (cases and positivity), date of hospital admission, or date of ED visit. Hospitalization data come from the Connecticut Hospital Association and are based on hospital location, not county of patient residence. COVID-19-like illness includes fever and cough or shortness of breath or difficulty breathing or the presence of coronavirus diagnosis code and excludes patients with influenza-like illness. All data are preliminary. These data are updated weekly and reflect the previous two full Sunday-Saturday (MMWR) weeks (https://wwwn.cdc.gov/nndss/document/MMWR_week_overview.pdf). These metrics were adapted from recommendations by the Harvard Global Institute and supplemented by existing DPH measures. For national data on COVID-19, see COVID View, the national weekly surveillance summary of U.S. COVID-19 activity, at https://www.cdc.gov/coronavirus/2019-ncov/covid-data/covidview/index.html DPH note about change from 7-day to 14-day metrics: Prior to 10/15/2020, these metrics were calculated using a 7-day average rather than a 14-day average. The 7-day metrics are no longer being updated as of 10/15/2020 but the archived dataset can be accessed here: https://data.ct.gov/Health-and-Human-Services/CT-School-Learning-Model-Indicators-by-County/rpph-4ysy As you know, we are learning more about COVID-19 all the time, including the best ways to measure COVID-19 activity in our communities. CT DPH has decided to shift to 14-day rates because these are more stable, particularly at the town level, as compared to 7-day rates. In addition, since the school indicators were initially published by DPH last summer, CDC has recommended 14-day rates and other states (e.g., Massachusetts) have started to implement 14-day metrics for monitoring COVID transmission as well. With respect to geography, we also have learned that many people are looking at the town-level data to inform decision making, despite emphasis on the county-level metrics in the published addenda. This is understandable as there has been variation within counties in COVID-19 activity (for example, rates that are higher in one town than in most other towns in the county).

    Connecticut Divorce Index, 1655-1953

    internal-ct.data.socrata.com | Last Updated 2024-08-12T18:00:58.000Z

    Divorce records are often a valuable source of information for researchers, as they can provide sometimes difficult to find information like a couple's date of marriage, the names of children, and a woman's maiden name. They also allow a fascinating insight into the values and mores surrounding marriage at the time. Connecticut began granting divorces in the mid-17th century, although only very, very sparingly at first. In the beginning only the General Assembly could grant a divorce; as the court system developed this eventually became mainly the purview of the superior courts, although the General Assembly continued to grant divorces until the early 20th century. This index is a combination of several different indexes created by Connecticut State Library staff over a period of many years. It contains divorce records for the following counties and dates: Fairfield: 1712-1941 Hartford: 1712-1953 Litchfield: 1751-1798, 1899-1927* Middlesex: 1786-1904 New Haven: 1712-1944 New London: 1712-1798* Tolland: 1786-1937 Windham: 1712-1798, 1907-1921* It also contains divorces granted by the General Assembly for 1655-1915. Divorce records for Litchfield, New London, and Windham Counties that fall in years not included in this list can be found in two books compiled by Barbara B. Ferris and Grace Louise Knox in the 1980s, located in the History & Genealogy reading room: <ul><li>Connecticut divorces: Superior court records for the counties of New London, Tolland & Windham, 1719-1910</li> <li>Connecticut divorces: Superior Court records for the counties of Litchfield, 1752-1922 and Hartford, 1740-1849</li></ul> Each entry in this list has a location of either a record or a file. Records are a brief summary of the case and the court's verdict that can be found in court record books. Files may have more information, such as the original divorce petition, statements from the litigants and witnesses, costs, and other material. To request a digital of physical copy of a record or file, please contact the staff of the <a href="https://libguides.ctstatelibrary.org/hg/home" target="blank_">History & Genealogy Unit</a> by telephone (860) 757-6580 or <a href="https://portal.ct.gov/csl/Email-Us?language=en_US" target="blank_">email</a>. There may be a small fee, depending on the size of the order and whether you would like a digital or physical copy. When requesting a copy of a record or file, please include the information from the relevant entry in the index. You are also more than welcome to visit the Connecticut State Library to see these materials for yourself! Note: Several volumes have extra, non-numbered pages at the end; these are denoted by a typographical mark and the word “misc.” *The February, 1769 term of the Superior Court in Fairfield is filed in a folder in the state archives RG 003, Superior Court Fairfield County Records/Dockets, Box 51. **Volume 19 contains miscellaneous papers at the end of the numbered pages. These papers are mostly in chronological order, and include court files, invoices, and the records of a few Superior Court terms. †Volume 21 contains miscellaneous papers at the end of the numbered pages. These papers are mostly in chronological order, and include court files and records for certain Superior Court terms. ††Volume 22 contains miscellaneous papers at the end of the numbered pages. These papers are mostly in chronological order, and include court files and records for certain Superior Court terms. ‡ Volume 28 contains miscellaneous papers at the end of the numbered pages. Some of these are a continuation of the August, 1793 session of the court at Litchfield.

    Connecticut COVID-19 Community Levels by County as Originally Posted - Archive

    data.ct.gov | Last Updated 2023-08-02T15:36:04.000Z

    This public use dataset has 11 data elements reflecting COVID-19 community levels for all available counties. This dataset contains the same values used to display information available at https://www.cdc.gov/coronavirus/2019-ncov/science/community-levels-county-map.html. CDC looks at the combination of three metrics — new COVID-19 admissions per 100,000 population in the past 7 days, the percent of staffed inpatient beds occupied by COVID-19 patients, and total new COVID-19 cases per 100,000 population in the past 7 days — to determine the COVID-19 community level. The COVID-19 community level is determined by the higher of the new admissions and inpatient beds metrics, based on the current level of new cases per 100,000 population in the past 7 days. New COVID-19 admissions and the percent of staffed inpatient beds occupied represent the current potential for strain on the health system. Data on new cases acts as an early warning indicator of potential increases in health system strain in the event of a COVID-19 surge. Using these data, the COVID-19 community level is classified as low, medium , or high. COVID-19 Community Levels can help communities and individuals make decisions based on their local context and their unique needs. Community vaccination coverage and other local information, like early alerts from surveillance, such as through wastewater or the number of emergency department visits for COVID-19, when available, can also inform decision making for health officials and individuals. See https://www.cdc.gov/coronavirus/2019-ncov/science/community-levels.html for more information. Visit CDC’s COVID Data Tracker County View* to learn more about the individual metrics used for CDC’s COVID-19 community level in your county. Please note that county-level data are not available for territories. Go to https://covid.cdc.gov/covid-data-tracker/#county-view.

    Index to Loyalist Connecticut Court Records, 1776-84

    internal-ct.data.socrata.com | Last Updated 2024-08-08T17:24:35.000Z

    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. People may request a copy of a file by contacting the staff of the History & Genealogy Unit by telephone (860) 757-6580 or <a href="https://portal.ct.gov/csl/email-us?language=en_US">email</a>. When requesting a copy of a record, please include the name of the individual, date, and the specific court.

    Connecticut Courts, Inquests into Deaths 1711-1892

    internal-ct.data.socrata.com | Last Updated 2024-07-03T13:50:27.000Z

    Records of the Judicial Department Papers by Subject. Index to Inquests of Connecticut Deaths, 1711-1892 Starting in 1639, the General Court of Connecticut requested the Deputy “to consider of some orders concerning an inquiry into the death of any that happen either accidently or by violence” (Connecticut Colonial Record, Vol. 48, Pg. 42). Later in 1650 a Code of Laws was adopted in Connecticut which also included a provision that in case of a “very sudden, untimely or unnatural death , some Magistrate or the Constable of that Town shall forthwith summon a Jury of six or twelve discreet men to inquire of the cause and manner of their death” (Connecticut Colonial Record, Vol. 48, Pg. 523). For more than two hundred years, inquests into untimely accidental or violent deaths was the prevue of the Connecticut court system until the Connecticut General Assembly established the Office of the Coroner on May 1, 1883. Records of pre-1883 untimely deaths were generally handled via the county or superior courts found in each Connecticut county. This index covers the years 1711-1892 and references 2,120 Inquests into untimely accidental or violent deaths files from various County & Superior Courts for Fairfield, Hartford, Litchfield, Middlesex, New Haven, New London, Tolland, and Windham counties. In some cases, particularly for Tolland and Windham counties, coroner or medical examiner reports for the 1883-1892 time period were filed with the court. 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, death year, town of death, cause of death, remarks of note taken from the document as well as the court and location of the original document.
