The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Block Groups (BGs) are defined before tabulation block delineation and numbering, but are clusters of blocks within the same census tract that have the same first digit of their 4-digit census block number from the same decennial census. For example, Census 2000 tabulation blocks 3001, 3002, 3003,.., 3999 within Census 2000 tract 1210.02 are also within BG 3 within that census tract. Census 2000 BGs generally contained between 600 and 3,000 people, with an optimum size of 1,500 people. Most BGs were delineated by local participants in the Census Bureau's Participant Statistical Areas Program (PSAP). The Census Bureau delineated BGs only where the PSAP participant declined to delineate BGs or where the Census Bureau could not identify any local PSAP participant. A BG usually covers a contiguous area. Each census tract contains at least one BG, and BGs are uniquely numbered within census tract. Within the standard census geographic hierarchy, BGs never cross county or census tract boundaries, but may cross the boundaries of other geographic entities like county subdivisions, places, urban areas, voting districts, OFM_2000-2013_SAEP_Population_and_Housing_Esimates_for_2010_Census_Block_Groups.htm[3/30/2017 2:08:07 PM] OFM 2000-2013 SAEP Population and Housing Esimates for 2010 Census Block Groups congressional districts, and American Indian / Alaska Native / Native Hawaiian areas. BGs have a valid code range of 0 through 9. BGs coded 0 were intended to only include water area, no land area, and they are generally in territorial seas, coastal water, and Great Lakes water areas. For Census 2000, rather than extending a census tract boundary into the Great Lakes or out to the U.S. nautical three-mile limit, the Census Bureau delineated some census tract boundaries along the shoreline or just offshore. The Census Bureau assigned a default census tract number of 0 and BG of 0 to these offshore, water-only areas not included in regularly numbered census tract areas. Purpose: The Washington State Office of Financial Management Small Area Estimate Program produces annual population and housing estimates for distinct geographic summary levels and distributes them in shapefile format for purposes of statistical enumeration, cartographic display and analysis.

The remaining attribute information has been examined but has not been fully tested for accuracy. Logical_Consistency_Report: The Census Bureau performed automated tests to ensure logical consistency and limits of shapefiles. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. All polygons are tested for closure. The Census Bureau uses its internally developed geographic update system to enhance and modify spatial and attribute data in the Census MAF/TIGER database. Standard geographic codes, such as FIPS codes for states, counties, municipalities, county subdivisions, places, American Indian/Alaska Native/Native Hawaiian areas, and congressional districts are used when encoding spatial entities. The Census Bureau performed spatial data tests for logical consistency of the codes during the compilation of the original Census MAF/TIGER database files. Most of the codes for geographic entities except states, counties, urban areas, Core Based Statistical Areas (CBSAs), American Indian Areas (AIAs), and congressional districts were provided to the Census Bureau by the USGS, the agency responsible for maintaining FIPS 55. Feature attribute information has been examined but has not been fully tested for consistency. For the TIGER/Line Shapefiles, the Point and Vector Object Count for the G-polygon SDTS Point and Vector Object Type reflects the number of records in the shapefile attribute table. For multi-polygon features, only one attribute record exists for each multi-polygon rather than one attribute record per individual G-polygon component of the multi-polygon feature. TIGER/Line Shapefile multi-polygons are an exception to the G-polygon object type classification. Therefore, when multi- polygons exist in a shapefile, the object count will be less than the actual number of G-polygons. Completeness_Report: Data completeness of the TIGER/Line Shapefiles reflects the contents of the Census MAF/TIGER database at the time the TIGER/Line Shapefiles were created.

A shapefile is a geospatial data format for use in geographic information system (GIS) software. Shapefiles spatially describe vector data such as points, lines, and polygons, representing, for instance, landmarks, roads, and lakes. The Environmental Systems Research Institute (Esri) created the format for use in their software, but the shapefile format works in additional Geographic Information System (GIS) software as well. 1.2 What are TIGER/Line Shapefiles?

  • Glossary of Redistricting Terms
    Glossary of Redistricting Terms Apportionment or Reapportionment Following each decennial census, seats in the United States House of Representatives are apportioned to each state based on population figures derived from the census. Apportionment is the process of determining how many Congressional Districts to allocate to each state, and is different from ‘redistricting,’ which involves redrawing district lines within a state. At-large An election in which candidates run in all parts of a jurisdiction rather than from districts or wards within the jurisdiction. All members of EVIT’s Board of Governors are elected from specific districts within EVIT’s boundary. There are no at-large election contests. Census Block The smallest level of census geography used by the Census Bureau to collect and report census data. Census Blocks are labeled with a four digit number such as 2025 or 1006A. Census Block Group A group of Census Blocks all having the same first block digit. Block 2025 is in Block Group 2. There are 1,023 whole or partial Block Groups within EVIT’s jurisdiction. The latest available population data for this redistricting process is at the Block Group level. Census data Information and statistics on the population of the United States gathered by the Census Bureau and released to the public. Census Tract A level of census geography larger than a census block or census block group that often corresponds to neighborhood boundaries. There are 385 whole or partial Census Tracts within EVIT’s boundary – too few for our purpose in redistricting. Community of interest An area that is defined by residents’ shared demographics or by common threads of social, economic, or political interests such that the area may benefit from common representation.

  • Census Bureau Public Geocoder
    1. What is Geocoding? Geocoding is an attempt to provide the geographic location (latitude, longitude) of an address by matching the address to an address range. The address ranges used in the geocoder are the same address ranges that can be found in the TIGER/Line Shapefiles which are derived from the Master Address File (MAF). The address ranges are potential address ranges, not actual address ranges. Potential ranges include the full range of possible structure numbers even though the actual structures might not exist. The majority of the address ranges we have are for residential areas. There are limited address ranges available in commercial areas. Our address ranges are regularly updated with the most current information we have available to us. The hypothetical graphic below may help customers understand the concept of geocoding and Census Geography (addresses displayed in this document are factitious and shown for example only.) If we look at Block 1001 in the example below the address range in red 101-199 is the range of numbers that overlap the actual individual house numbers associated with the blue circles (e.g. 103, 117, 135 and 151 Main St) on that side of the street (i.e. the Left side, note the arrow is pointing to the right on Main Street.) Based on this logic, the from address would be 101 and the to address would be 199 for this address range. Besides providing a user with the geographic location of an address the Census Geocoder can also provide all of the additional Census geographic information associated with a location, for example a Census Block, Tract, County, and State.

  • 2030 Wisconsin State Airport System Plan
    8.0 Environmental Justice 8.1 Chapter Purpose and Content Wisconsin is committed to integrating the principle of environmental justice into all transportation planning programs and activities. For purposes of this chapter, environmental justice populations are defined as including minority, low-income, children (age 17 and under), seniors (age 65 and older) and zero-vehicle household populations. These environmental justice populations have been assessed in relation to their geographic location, and the presence and operations of the statewide airport system. The information contained in this chapter includes an evaluation of the relationship between the Wisconsin State Airport System Plan (SASP) recommendations and environmental justice populations. This environmental justice chapter also supplements the system plan environmental evaluation included in Chapter 9, which discusses the potential environmental and community impacts of implementing the SASP. Lastly, this chapter identifies areas for consideration during future planning and project-level activities. It is important to note that this evaluation discusses the SASP recommendations at a state-wide system level. Prior to implementation of each individual project, individual project specific environmental reviews will be completed which will include an environmental justice evaluation. The implementation of any specific improvement identified in this plan remains the responsibility of local airport sponsors, and the projects identified do not constitute a commitment of either state or federal funding. The approval and project justification of local master planning efforts, environmental review processes and funding approvals remain a sponsor responsibility. Similar to Wisconsin’s Long-Range Transportation Plan (Connections 2030), the SASP is a policy- based plan developed to be flexible and responsive to shifts in investment priorities.

  • Historical Glossary (2010S)
    Historical Glossary (2010s) A American Community Survey (ACS) An ongoing census survey sent to a sample of three million housing units annually. The ACS collects detailed demographic and socioeconomic population and housing characteristics, similar to the information collected on the former long-form census questionnaire. The data is collected continuously rather than once a decade, so the ACS provides more current data. Single‐year estimates are available annually for geographic areas with a population of 65,000 or more. Three‐year estimates are available annually for geographic areas with a population of 20,000 or more. In December 2010, the first five‐year estimates at the census tract and block group level were made available. Anglo Those persons who identified their race on the census form as White only and not Hispanic. Assignment unit Any unit of geography that may be used as a building block to draw a redistricting plan. Assignment units available in RedAppl are counties, census tracts, census block groups, census blocks, and VTDs (voting tabulation districts). B Black Those persons who identified their race on the census form as Black, African American, or Negro only or Black and any other race. Black persons can be either Hispanic or non-Hispanic. Black + Hispanic A combined population category that includes all persons who identified their race as Black and all persons who identified themselves as Hispanic. The total is adjusted so that those who indicated they were both Black and Hispanic are not counted twice. The category is frequently examined for redistricting purposes in areas in which Black and Hispanic voters may form political coalitions or vote together as a bloc.

  • Geographic Levels in NEO CANDO 2010+
    Geographic Levels in NEO CANDO 2010+ Data in NEO CANDO 2010+ are available at several levels of aggregation including census geographies and locally defined geographies. Descriptions of each of the different aggregations are provided below. For more detailed information about the census geographies click here. All of the data in NEO CANDO 2010+ are based on 2010 tract boundary definitions. In addition to the 2010 Census and estimates from the American Community Survey (ACS), NEO CANDO 2010+ provides estimates of the 2000 census data in 2010 census geography. Because of changes in boundaries between 2000 and 2010, we have estimated the 2000 data using apportionment methods. We also geocode data we receive at the address level and assign and aggregate it to the 2010 census geography. Census tract level data are available for the following 17 counties: Ashland, Ashtabula, Columbiana, Cuyahoga, Erie, Geauga, Huron, Lake, Lorain, Mahoning, Medina, Portage, Richland, Stark, Summit, Trumbull, and Wayne. Keep in mind that some census tracts have changed numbers, been split, or changed physical boundaries over the last decade. Analysis of trends over time requires that data be based on the same geographic boundaries. A tract that existed in 2000 may not exist in 2010; the tract number may have changed, or the physical boundaries may have changed. We ensure the user is comparing apples to apples by converting all of our data in NEO CANDO 2010+ into the same geographic boundaries -- 2010 geography. The user should not compare data in the 2000 geography to data in the 2010 geography. CENSUS GEOGRAPHIES1 Census Block Census blocks are the smallest census geography.

    3. Geographic Shapefile Concepts Overview The following sections describe the geographic entity type displayed in each shapefile, as well as the record layout for each file, in alphabetical order. A listing of all available shapefiles, including vintage and geographic level (state, county, and national), precedes the description of the entity type. 3.1 American Indian / Alaska Native / Native Hawaiian (AIANNH) Areas 3.1.1 Alaska Native Regional Corporations (ANRCs) Alaska Native Regional Corporations geography and attributes are available for Alaska in the following shapefile: Alaska Native Regional Corporation (ANRC) State Shapefile (Current) ANRCs are corporations created according to the Alaska Native Claims Settlement Act (Pub. L. 92–203, 85 Stat. 688 (1971); 43 U.S.C. 1602 et seq. (2000)). The laws of the State of Alaska organize “Regional Corporations” to conduct both the for-profit and non-profit affairs of Alaska Natives within defined regions of the state. The Census Bureau treats ANRCs as legal geographic entities. Twelve ANRCs cover the entire State of Alaska except for the area within the Annette Island Reserve (an American Indian Reservation under the governmental authority of the Metlakatla Indian Community). There is a thirteenth ANRC that represents the eligible Alaska Natives living outside of Alaska that are not members of any of the twelve ANRCs within the State of Alaska. Because it has no defined geographic extent, this thirteenth ANRC does not appear in the TIGER/Line Shapefiles and the Census Bureau does not provide data for it. The Census Bureau offers representatives of the twelve ANRCs the opportunity to review and update the ANRC boundaries.

  • A Precinct Too Far: Turnout and Voting Costs – Online Appendix
    A Precinct Too Far: Turnout and Voting Costs – Online Appendix Enrico Cantoni* February 11, 2019 A Election Calendars The electoral calendars of the two states were remarkably similar in 2012 through 2016. Both held U.S. Senate elections in 2012 and 2014, voted for governor in 2014, and held presidential primaries on March 1, 2016; in addition, the most pop- ulous cities in the two states (Boston and Minneapolis) held mayoral elections in November 2013. In the 2012 presidential election, Massachusetts and Minnesota allowed no form of early voting and required a valid excuse to vote absentee by mail.1 Thus, the only legitimate way most voters had to cast their ballots was by traveling to their assigned polling places on Election Day.2 Unlike the voters in Massachusetts, where an ex- *Department of Economics, University of Bologna, Piazza Scaravilli 2, 40126, Bologna (BO), Italy (e-mail: [email protected]). 1Valid excuses in MA being: absence on Election Day for any reason, physical disability, or religious beliefs (M.G.L. ch.50 §1; M.G.L. ch.54 §86; M.G.L. ch.54 §89). 2Massachusetts state law prescribes stiff penalties for those who make a false absentee ballot application: a fine of up to $10,000 and up to five years in prison (M.G.L. ch.56 §5). Although it is difficult to assess the extent of illegal absentee voting, practical reasons suggest that to be lim- ited. Most importantly, casting an absentee ballot is far from automatic. An application needs to be mailed or hand-delivered to the elections office before each election.
