,This feature layer represents the boundaries of Connecticut's congressional districts based on the latest redistricting process following the 2020 Census. More information about the 2021 Redistricting Project can be found here.,The dataset includes the five congressional districts with fields identifying the current U.S. House Representative and their associated political party for each district. The geometry is derived from the published data from the Connecticut General Assembly.,The CT Congressional Representations are as described here.,,,Collection of CT Legislative District published feature layers:,,,Attributes

,This CT Counties layer consists of individual polygons representing each of the 8 counties that make up the state of Connecticut.,This feature layer is directly derived from the CTDOT Municipalities feature layer geometry, created by CT Department of Transportation. The municipalities are dissolved into their associated counties.,This feature layer includes US Census Federal Information Processing Standards (FIPS) codes that are associated with each municipality. This was included based on information from Connecticut County to County Subdivision Crosswalk from the US Census.,The 9 Planning Regions in Connecticut have replaced the counties for statistical and administrative functions, so these 8 counties are used only in legacy geography.,Connecticut’s 9 planning regions provide a geographic framework within which municipalities can jointly address common interests and coordinate such interests with state plans and programs. CGS Section 16a-4a authorizes the Secretary of the Office of Policy and Management (OPM) to designate or redesignate the boundaries of logical planning regions. CGS Section 4-124j authorizes the member municipalities of each planning region to establish a formal regional governance structure known as a council of governments (COG).,For more information see:,

Connecticut Senate Districts is not intended for maps printed at map scales greater or more detailed than 1:100,000 scale (1 inch = 1.578 mile).

,This CT Full State layer consists of two individual polygons representing the land and Long Island Sound borders that make up the state of Connecticut.,This land portion of this feature layer is directly derived from the CTDOT Municipalities feature layer geometry, created by CT Department of Transportation. The full state is created by dissolving all the municipalities into one polygon.,The Long Island Sound portion is derived from points defining the Connecticut state waters boundary line, as described in the CTDEEP Marine Fisheries Information Circular (Table 6).,This feature layer includes US Census Federal Information Processing Standards (FIPS) codes that are associated with the state of Connecticut.,,

,This CT Councils of Governments layer consists of individual polygons representing each of the 9 regional Councils of Governments (COGs) that make up the state of Connecticut.,This feature layer is directly derived from the CTDOT Municipalities feature layer geometry, created by CT Department of Transportation.

The 2020 cartographic boundary KMLs are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. State Legislative Districts (SLDs) are the areas from which members are elected to State legislatures. The SLDs embody the upper (senate) and lower (house) chambers of the state legislature. Nebraska has a unicameral legislature and the District of Columbia has a single council, both of which the Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation; there are no data by SLDL for either Nebraska or the District of Columbia. A unique three-character census code, identified by State participants, is assigned to each SLD within a state. In Connecticut, Illinois, Louisiana, Maine, Maryland, Massachusetts, Michigan, Ohio, and Puerto Rico, the Redistricting Data Program (RDP) participant did not define the SLDs to cover all of the state or state equivalent area. In these areas with no SLDs defined, the code "ZZZ" has been assigned, which is treated as a single SLD for purposes of data presentation. The generalized boundaries in this file are based on the most recent state legislative district boundaries collected by the Census Bureau for the 2018 election year and provided by state-level participants through the RDP.
