These are the Traffic Analysis Zones (TAZ) used in the Statewide Travel Model. This dataset contains only basic geographic information about the zones.TAZ boundaries are defined based on Census geographies (block, block group and tract). Care has been taken so that TAZ nest within Census tracts wherever possible in order for more direct matching with Census data. TAZ boundaries are also defined by major transportation facilities (such as roadways or rail lines), major environmental features (such as rivers), and with underlying land uses. The relative size of the TAZ was also a factor in deciding new TAZ boundaries if the zone size was large and the zone was thought to have a significant amount of socioeconomic activity. The size of TAZ varies from under 10 acres in the downtown to more than 100,000 acres in the mountain or lake zones. The average zone size is approximately 350 acres, which is a little over ½ square mile. Generally, TAZ in urban areas are smaller than in suburban and rural areas.There are currently 5 travel model spaces in Utah: Cache MPO (2), Dixie MPO (3), Summit (4), UDOT rural areas (0), and the combined WFRC/MAG MPO (1) model space. The model space indicators shown in parentheses above are coded in the Subarea_ID field. As travel demand model software requires that each TAZ be uniquely identified starting with the number 1, each model space has assigned its own unique TAZ identifier numbering sequence which is coded into the SubAreaTAZID field. However, this rule also applies to the statewide travel model, which is an aggregation of all the TAZs from the five model spaces into a single layer. In this statewide layer, the TAZID field is the unique identifier for the Utah Statewide Travel Model (USTM). CO_TAZID is the field used to link each TAZ to its socioeconomic data. It is a combination of the County FIPS number and a TAZ identifier within the county or from within an MPO model space.

A TAZ usually consists of one or more census blocks, block groups, or census tracts. These geographic units were generated for 2020 by BMC staff in consultation with member jurisdictions. The Census Bureau discontinued TAZs as an official geography prior to the 2020 Census. This is the official GIS dataset that will be used for modeling travel demand at BMC. This TAZ dataset includes the BMC region jurisdictions only. Traffic analysis zones (TAZs) are basic spatial units of analysis facilitating the ability of transportation planners to forecast changes in commuting patterns, trip volumes, and modes of travel, and to develop plans to meet the changing demands for transportation facilities and capacities. Each TAZ represents an area containing similar kinds of land use and commuter travel.FIELDSSTATEFP20 - State (FIPS)COUNTYFP20 - County (FIPS)NAME - TAZ NameTAZ20 - TAZ NumberJUR - Jurisdiction Number (BMC internal)JURNAME - Jurisdiction NameRPD20 - RPD NumberRPDNAME - RPD NameACRES - Land area in acresDate: 02/24/2022Update: None planned, 2030 boundaries will be added separatelySource: Baltimore Metropolitan Council

This dataset provides data on Qualified Census Tracts for the Low-Income Housing Tax Credit Program for 2024. LIHTC Qualified Census Tracts, as defined under the section 42(d)(5)(C) of the of the Internal Revenue Code of 1986, include any census tract (or equivalent geographic area defined by the Bureau of the Census) in which at least 50 percent of households have an income less than 60 percent of the Area Median Gross Income (AMGI), or which has a poverty rate of at least 25 percent. Maps of Qualified Census Tracts and Difficult Development Areas are available at: huduser.gov/sadda/sadda_qct.html .

Traffic analysis zones (TAZs) are special-purpose geographic entities delineated by state and local transportation officials for tabulating traffic related data from the decennial census, especially journey-to-work and place-of-work statistics. A TAZ usually consists of one or more census blocks, block groups, or census tracts. For Census 2000 TAZs are defined within county. Each TAZ is identified by a 6-character alphanumeric census code that is unique within county or statistically equivalent entity. A code of ZZZZZZ indicates a portion of a county where no TAZs were defined. The U.S. Census Bureau first provided data for TAZs in the 1980 census, when it identified them as 'traffic zones.' For the 1990 census, the TAZs were defined within Census Transportation Planning Package (CTPP) areas. TAZs were not shown in any 1990 Census TIGER extracts. The U.S. Census Bureau subsequently inserted the TAZs into the Census TIGER database and began extracting them starting with the 1994 TIGER/Line files. The Census 2000 TAZ program was conducted on behalf of the Federal Highway Administration, Department of Transportation, which offered participation to the Metropolitan Planning Organizations (MPOs) and the Departments of Transportation (DOTs) in the 50 states and the District of Columbia. The following states did not have a participating MPO or State DOT for the Census 2000 TAZ Program: Delaware, Hawaii, Montana.

Transportation analysis zones are subdivisions of counties that are delineated for land use and travel analysis purposes. The geography for this file is based on the Twin Cities Regional Travel Demand Forecast Model.

Notes:

- Since 2004, this set of TAZs is the official TAZ system for travel demand modeling, socioeconomic forecasts and community comprehensive plan development, in addition to its existing use for the 2000 Census Transportation Planning Package (CTPP).

- Population, households and employment forecasts by TAZ, published with this file during 2004-2013, have been replaced with newer forecasts adopted by Metropolitan Council, starting in May 2014.

- This system is a modification of an earlier TAZ system developed by Minnesota Department of Transportation and Metropolitan Council in late 1989, referred to as Transportation Analysis Zones 1990 (TAZ1990). The principal difference between the 1990 and 2000 systems is that 27 TAZs were subdivided into smaller units, thus expanding the total number of TAZs from 1165 to 1201.

- Generally, the 2000 TAZ system utilized TIGER line files for 2000 Census blocks and political boundaries, which do not necessarily match the positionally accurate street-line files and political boundaries typically used with other Council generated GIS datasets.

A Qualified Census Tract (QCT) is any census tract (or equivalent geographic area defined by the Census Bureau) in which at least 50% of households have an income less than 60% of the Area Median Gross Income (AMGI). HUD has defined 60% of AMGI as 120% of HUD's Very Low Income Limits (VLILs), which are based on 50% of area median family income, adjusted for high cost and low income areas.

A traffic analysis zone is the unit of geography most commonly used in conventional transportation planning models. The size of a zone varies, but for a typical metropolitan area, a zone of under 3000 people is common. The spatial extent of zones typically varies in models, ranging from very large areas in the suburb to as small as city blocks or buildings in central business districts. Zones are constructed by census block information. Typically these blocks are used in transportation models by providing socio-economic data. States differ in the socio-economic data that they attribute to the zones. Most often the critical information is the number of automobiles per household, household income, and employment within these zones. This information helps to further the understanding of trips that are produced and attracted within the zone. These zones can change or altered to eliminate unneeded areas to limit the "computational burden."

This dataset is intended for researchers, students, and policy makers for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analysis with other spatial data.

These are the Traffic Analysis Zones (TAZ) used in the Wasatch Front Travel Model. This dataset contains only basic geographic information about the zones.The Wasatch Front travel model region covers the urbanized portion of Weber, Davis, Salt Lake and Utah Counties and the portion of the Box Elder County from Brigham City South (Salt Lake City-West Valley City, Ogden-Layton, and Provo-Orem Urbanized Areas). The region is divided into 2,881 Traffic Analysis Zones (TAZ). TAZ boundaries are defined based on Census geographies (block, block group and tract). Care has been taken so that TAZ nest within Census tracts wherever possible in order for more direct matching with Census data. TAZ boundaries are also defined by major transportation facilities (such as roadways or rail lines), major environmental features (such as rivers), and with underlying land uses. The relative size of the TAZ was also a factor in deciding new TAZ boundaries if the zone size was large and the zone was thought to have a significant amount of socioeconomic activity. The size of TAZ varies from under 10 acres in the downtown to more than 100,000 acres in the mountain or lake zones. The average zone size is approximately 350 acres, which is a little over ½ square mile. Generally, TAZ in urban areas are smaller than in suburban and rural areas.

This 'Redistricting' version of the census data is the first release of the data.

This 2000 census redistricting geography database of the 7 county metropolitan area and the additional 12 collar county area was developed from the U.S. Census Bureau's Redistricting Census 2000 TIGER/Line files.

The Metropolitan Council downloaded this data from the Census Bureau's FTP site, imported it into ArcInfo coverage format, added a few items to the coverage, then created block, block group, tract, county subdivision (city), county, taz and water coverages and shape files from the original data.

A traffic analysis zone (TAZ) is a geographic unit used in transportation planning models. TAZs are used to represent the spatial distribution of trip origins and destinations. TAZ boundaries are defined based on Census geographies (block, block group and tract). Care has been taken so that TAZs nest within Census tracts wherever possible in order for more direct matching with Census data. TAZ boundaries are also defined by major transportation facilities (such as roadways), major environmental features (such as rivers), and with underlying land uses. The relative size of the TAZ was also a factor in determining new TAZ boundaries if the zone size was large and the zone was thought to have a significant amount of socioeconomic activity.

description: Census Tract Data - Census 2000 This data layer represents Census 2000 demographic data derived from the PL94-171 redistricting files and SF3. Census geographic entities include blocks, blockgroups and tracts. Tiger line files are the source of the geometry representing the Census blocks. Attributes include total population counts, racial/ethnic, and poverty/income information. Racial/ethnic classifications are represented in units of blocks, blockgroups and tracts. Poverty and income data are represented in units of blockgroups and tracts. Percentages of each racial/ethnic group have been calculated from the population counts. Total Minority counts and percentages were compiled from each racial/ethnic non-white category. Categories compiled to create the Total Minority count includes the following: African American, Asian, American Indian, Pacific Islander, White Hispanic, Other and all mixed race categories. The percentage poverty attribute represents the percent of the population living at or below poverty level. The per capita income attribute represents the sum of all income within the geographic entity, divided by the total population of that entity. Special fields designed to be used for EJ analysis have been derived from the PL data and include the following: Percentage difference of block, blockgroup and total minority from the state and county averages, percentile rank for each percent total minority within state and county entities. Food Desert Locator Documenation The Healthy Food Financing Initiative (HFFI) Working Group defines a food desert as a low-income census tract where a substantial number or share of residents has low access to a supermarket or large grocery store. To qualify as low-income, census tracts must meet the Treasury Department's New Markets Tax Credit (NMTC) program eligibility criteria. Furthermore, to qualify as a food desert tract at least 33% of the tract's population (or a minimum of 500 people) must have low access to a supermarket or large grocery store. Low access to a healty food retail outlet is defined as more than 1 mile from a supermarket or large grocery store in urban ares and as more than 10 miles in rural areas.

A census tract is a statistical subdivision of counties that may include just a few neighborhoods in a city or, in rural areas, may include several towns. HUD designates Qualified Census Tracts (QCTs) for purposes of the Low Income Housing Tax Credit (LIHTC) program. To qualify, census tract must either: demonstrate a poverty rate of at least 25 percent, or 50 percent or more of its householders must have incomes below 60 percent of the area median household income.

The Low-Income Housing Tax Credit (LIHTC) is the most important resource for creating affordable housing in the United States today. The LIHTC database, created by HUD and available to the public since 1997, contains information on 48,672 projects and 3.23 million housing units placed in service since 1987. Low-Income Housing Tax Credit Qualified Census Tracts must have 50 percent of households with incomes below 60 percent of the Area Median Gross Income (AMGI) or have a poverty rate of 25 percent or more. Difficult Development Areas (DDA) are areas with high land, construction and utility costs relative to the area median income and are based on Fair Market Rents, income limits, the 2010 census counts, and 5-year American Community Survey (ACS) data.
