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.

Connecticut Divorce Index, 1655-1953
internal-ct.data.socrata.com | Last Updated 2024-08-12T18:00:58.000ZDivorce 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.

COVID-19 Updated (Bivalent) Vaccination Coverage By Race/Ethnicity and Age Group - ARCHIVED
data.ct.gov | Last Updated 2023-08-07T17:07:17.000Z<strong>These tables will stop being updated after June 1, 2023. COVID-19 vaccination reporting is expected to resume when a new COVID-19 vaccination formulation is authorized.</strong></p> As 4/22/2023, CDC recommends bivalent vaccine for everyone regardless of age and whether or not the person has had prior monovalent vaccine. This table shows the cumulative number and percentage of people who have received an updated (bivalent) COVID-19 vaccination by race/ethnicity and age group for people 5 years and over. • Data are reported weekly on Thursday and include doses administered to Saturday of the previous week. • All data in this report are preliminary. Data for previous weeks may be changed because of delays in reporting, deduplication, or correction of errors. • The table groups people based on their current age and excludes people known to be deceased. • The analyses here are based on data reported to CT WiZ which is the immunization information system for CT. Connecticut COVID-19 Vaccine Program providers are required to report to CT WiZ all COVID-19 doses administered in CT including to CT residents and to residents of other jurisdictions. CT Wiz also receives records on CT residents vaccinated in other jurisdictions and by federal entities which share data with CT WiZ electronically (currently: RI, NJ, New York City, DE, Philadelphia, NV, Indian Health Service, Department of Veterans Affairs (doses administered since 11/2022)). Electronic data exchange is being added jurisdiction-by-jurisdiction. Once a jurisdiction is added to CT WiZ, the records for residents of that jurisdiction vaccinated in CT are removed. For example, when CT residents vaccinated in NYC were added, NYC residents vaccinated in CT were removed. • Population size estimates used to calculate cumulative percentages are based on 2020 DPH provisional census estimates*. • Race and ethnicity data may be self-reported or taken from an existing electronic health care record. Reported race and ethnicity information is used to create a single race/ethnicity variable. People with Hispanic ethnicity are classified as Hispanic regardless of reported race. People with a missing ethnicity are classified as non-Hispanic. People with more than one race are classified as multiple races. A vaccine coverage percentage cannot be calculated for people classified as NH (non-Hispanic) Other race or NH Unknown race since there are no population size estimates for these groups. Data quality assurance activities suggest that in at least some cases NH Other may represent a missing value. Vaccine coverage estimates in specific race/ethnicity groups may be underestimated as result of the classification of records as NH Unknown Race or NH Other Race. • Cumulative percentage estimates have been capped at 100%. Observed percentages may be higher than 100% for multiple reasons, inaccuracies in the census denominators or reporting errors. * DPH Provisional State and County Characteristics Estimates April 1, 2020.

Connecticut Courts, Inquests into Deaths 1711-1892
internal-ct.data.socrata.com | Last Updated 2024-07-03T13:50:27.000ZRecords 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.

Index to Loyalist Connecticut Court Records, 1776-84
internal-ct.data.socrata.com | Last Updated 2024-08-08T17:24:35.000ZThis 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.

Connecticut COVID-19 Community Levels by County as Originally Posted - Archive
data.ct.gov | Last Updated 2023-08-02T15:36:04.000ZThis 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.

Litchfield County Court African Americans and Native Americans Collection, 1753 - 1852
internal-ct.data.socrata.com | Last Updated 2024-07-31T13:10:57.000Z<strong>PLEASE NOTE: This is an index of a historical collection that contains words and phrases that may be offensive or harmful to individuals investigating these records</strong>. In order to preserve the objectivity and historical accuracy of the index, State Archives staff took what would today be considered archaic and offensive descriptions concerning race, ethnicity, and gender directly from the original court papers. For more information on appropriate description, please consult the <a href="https://www.diversitystyleguide.com/"><u>Diversity Style Guide</u></a> and <a href="https://archivesforblacklives.files.wordpress.com/2019/10/ardr_final.pdf"><u>Archives for Black Lives in Philadelphia: Anti-Racist Description Resources</u></a>. The Litchfield County Court African Americans and Native Americans Collection is an artificial collection consisting of photocopies of cases involving persons of African descent and indigenous people from the <em>Files </em>and <em>Papers by Subject </em>series of Litchfield County Court records. This collection was created in order to highlight the lives and experiences of underrepresented groups in early America, and make them more easily accessible to researchers.<br /> <strong>Collection Overview</strong> The collection consists of records of 188 court cases involving either African Americans or Native Americans. A careful search of the Files for the Litchfield County Court discovered 165 on African Americans and 23 on Native Americans, about one third of the total that was found in Files for the New London County Court for the period up to the American Revolution. A couple of reasons exist for this vast difference in numbers. First, Litchfield County was organized much later than New London, one of Connecticut's four original counties. New London was the home of four of seven recognized tribes, was a trading center, and an area of much greater wealth. Second, minority population in the New London County region has been tracked and tabulated by Barbara Brown and James Rose in Black Roots of Southeastern Connecticut.<sup>1</sup> Although this valuable work does not include all of Negro or Indian background, it provides a wonderful starting point and it has proven to be of some assistance in tracking down minorities in Litchfield County. In most instances, however, identification is based upon language in the documents and knowledge of surnames or first names.<sup>2</sup> Neither surname nor first name provides an invariably reliable guide so it is possible that some minorities have been missed and some persons included that are erroneous. In thirteen of 188 court cases, the person of African or Native American background cannot be identified even by first name. He or she is noted as "my Negro," a slave girl, or an Indian. In twenty-three lawsuits, a person with a first name is identified as a Negro, as an Indian in two other cases, and Mulatto in one. In the remaining 151 cases, a least one African American or Native American is identified by complete name.<sup>3</sup> Thirteen surnames recur in three or more cases.<sup>4</sup> A total of seventy surnames, some with more than one spelling, are represented in the records. The Jacklin surname appears most frequently represented in the records. Seven different Jacklins are found in eighteen cases, two for debt and the remaining sixteen for more serious crimes like assault, breach of peace, keeping a bawdy house, and trespass.<sup>5</sup> Ten cases concern Cuff Kingsbury of Canaan between 1808 and 1812, all involving debts against Kingsbury and the attempts of plaintiffs to secure writs of execution against him. Cyrus, Daniel, Ebenezer, Jude, Luke, Martin, Nathaniel, Pomp, Titus, and William Freeman are found in nine cases, some for debt, others for theft, and one concerning a petition to appoint a guardian for aged and incompe

To protect confidentiality, if a town has fewer than 5 cases or positive NAAT tests over the past 7 days, those data will be suppressed. COVID-19 cases and associated deaths that have been reported among Connecticut residents, broken down by race and ethnicity. All data in this report are preliminary; data for previous dates will be updated as new reports are received and data errors are corrected. Deaths reported to the either the Office of the Chief Medical Examiner (OCME) or Department of Public Health (DPH) are included in the COVID-19 update. The following data show the number of COVID-19 cases and associated deaths per 100,000 population by race and ethnicity. Crude rates represent the total cases or deaths per 100,000 people. Age-adjusted rates consider the age of the person at diagnosis or death when estimating the rate and use a standardized population to provide a fair comparison between population groups with different age distributions. Age-adjustment is important in Connecticut as the median age of among the non-Hispanic white population is 47 years, whereas it is 34 years among non-Hispanic blacks, and 29 years among Hispanics. Because most non-Hispanic white residents who died were over 75 years of age, the age-adjusted rates are lower than the unadjusted rates. In contrast, Hispanic residents who died tend to be younger than 75 years of age which results in higher age-adjusted rates. The population data used to calculate rates is based on the CT DPH population statistics for 2019, which is available online here: https://portal.ct.gov/DPH/Health-Information-Systems--Reporting/Population/Population-Statistics. Prior to 5/10/2021, the population estimates from 2018 were used. Rates are standardized to the 2000 US Millions Standard population (data available here: https://seer.cancer.gov/stdpopulations/). Standardization was done using 19 age groups (0, 1-4, 5-9, 10-14, ..., 80-84, 85 years and older). More information about direct standardization for age adjustment is available here: https://www.cdc.gov/nchs/data/statnt/statnt06rv.pdf Categories are mutually exclusive. The category “multiracial” includes people who answered ‘yes’ to more than one race category. Counts may not add up to total case counts as data on race and ethnicity may be missing. Age adjusted rates calculated only for groups with more than 20 deaths. Abbreviation: NH=Non-Hispanic. Data on Connecticut deaths were obtained from the Connecticut Deaths Registry maintained by the DPH Office of Vital Records.

Caution should be taken when making comparisons of percentages calculated using the 2019 and 2020 census estimates since observed difference may result from the shift in the denominator. The age groups in the state-level data tables will also be changing as a result of the switch to the new denominator. * DPH Provisional State and County Characteristics Estimates April 1, 2020.

Connecticut Department of Public Health, Health Statistics & Surveillance, SAR, Hartford, CT. _________________________________________________________________________________________ This table shows the number and percent of people that have initiated COVID-19 vaccination, are fully vaccinated and had additional dose 1 by race / ethnicity and age group. All data in this report are preliminary; data for previous dates will be updated as new reports are received and data errors are corrected. The age groups in the state-level data tables will also be changing as a result of the switch to the new denominator. Population size estimates are based on 2019 DPH census estimates until 5/26/2022. From 6/1/2022, 2020 DPH provisional census estimates are used. In the data shown here, a person who has received at least one dose of COVID-19 vaccine is considered to have initiated vaccination. A person is considered fully vaccinated if he/she has completed a primary vaccination series by receiving 2 doses of the Pfizer, Novavax or Moderna vaccines or 1 dose of the Johnson & Johnson vaccine. The fully vaccinated are a subset of the people who have received at least one dose. A person who completed a Pfizer, Moderna, Novavax or Johnson & Johnson primary series (as defined above) and then had an additional monovalent dose of COVID-19 vaccine is considered to have had additional dose 1. The additional dose may be Pfizer, Moderna, Novavax or Johnson & Johnson and may be a different type from the primary series. For people who had a primary Pfizer or Moderna series, additional dose 1 was counted starting August 18th, 2021. For people with a Johnson & Johnson primary series additional dose 1 was counted starting October 22nd, 2021. For most people, additional dose 1 is a booster. However, additional dose 1 may represent a supplement to the primary series for a people who is moderately or severely immunosuppressed. Bivalent booster administrations are not included in the additional dose 1 calculations. The percent with at least one dose many be over-estimated, and the percent fully vaccinated and with additional dose 1 may be under-estimated because of vaccine administration records for individuals that cannot be linked because of differences in how names or date of birth are reported. Race and ethnicity data may be self-reported or taken from an existing electronic health care record. Reported race and ethnicity information is used to create a single race/ethnicity variable. People with Hispanic ethnicity are classified as Hispanic regardless of reported race. People with a missing ethnicity are classified as non-Hispanic. People with more than one race are classified as multiple races.

It also shows the number of people who have not received vaccine and who are not yet fully vaccinated. All data in this report are preliminary; data for previous dates will be updated as new reports are received and data errors are corrected. A person who has received at least one dose of any vaccine is considered to have initiated vaccination. A person is considered fully vaccinated if they have completed a primary series by receiving 2 doses of the Pfizer, Novavax or Moderna vaccines or 1 dose of the Johnson & Johnson vaccine. The fully vaccinated are a subset of the number who have received at least one dose. The percent with at least one dose many be over-estimated and the percent fully vaccinated may be under-estimated because of vaccine administration records for individuals that cannot be linked because of differences in how names or date of birth are reported. Population data obtained from the 2019 Census ACS (www.census.gov) Geocoding is used to determine the census tract in which a person lives. People for who a census tract cannot be determined based on available address data are not included in this table. DPH recommends that these data are primarily used to identify areas that require additional attention rather than to establish and track the exact level of vaccine coverage. Census tract coverage estimates can play an important role in planning and evaluating vaccination strategies. However, inaccuracies in the data that are inherent to population surveillance may be magnified when analyses are performed down to the census tract level. We make every effort to provide accurate data, but inaccuracies may result from things like incomplete or inaccurate addresses, duplicate records, and sampling error in the American Community Survey that is used to estimate census tract population size and composition. These things may result in overestimates or underestimates of vaccine coverage. Some census tracts are suppressed. This is done if the number of people vaccinated is less than 5 or if the census population estimate is considered unreliable (coefficient of variance > 30%). Coverage estimates over 100% are shown as 100%. Connecticut COVID-19 Vaccine Program providers are required to report information on all COVID-19 vaccine doses administered to CT WiZ, the Connecticut Immunization Information System. Data on doses administered to CT residents out-of-state are being added to CT WiZ jurisdiction-by-jurisdiction. Doses administered by some Federal entities (including Department of Defense, Department of Correction, Department of Veteran’s Affairs, Indian Health Service) are not yet reported to CT WiZ. Data reported here reflect the vaccination records currently reported to CT WiZ. Caution should be used when interpreting coverage estimates in towns with large college/university populations since coverage may be underestimated. In the census, college/university students who live on or just off campus would be counted in the college/university town. However, if a student was vaccinated while studying remotely in his/her hometown, the student may be counted as a vaccine recipient in that town. As part of continuous data quality improvement efforts, duplicate records were removed from the COVID-19 vaccination data during the weeks of 4/19/2021 and 4/26/2021. As of 1/13/2021, census tract level data are provider by town for all ages. Data by age group is no longer available.
