    Description

    The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Metropolitan Divisions subdivide a Metropolitan Statistical Area containing a single core urban area that has a population of at least 2.5 million to form smaller groupings of counties or equivalent entities. Not all Metropolitan Statistical Areas with urban areas of this size will contain Metropolitan Divisions. Metropolitan Division are defined by the Office of Management and Budget (OMB) and consist of one or more main counties or equivalent entities that represent an employment center or centers, plus adjacent counties associated with the main county or counties through commuting ties. Because Metropolitan Divisions represent subdivisions of larger Metropolitan Statistical Areas, it is not appropriate to rank or compare Metropolitan Divisions with Metropolitan and Micropolitan Statistical Areas. The Metropolitan Divisions boundaries are those defined by OMB based on the 2010 Census, published in 2013, and updated in 2017.

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. Metropolitan and Micropolitan Statistical Areas are together termed Core Based Statistical Areas (CBSAs) and are defined by the Office of Management and Budget (OMB) and consist of the county or counties or equivalent entities associated with at least one urban core (urbanized area or urban cluster) of at least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with the counties containing the core. Categories of CBSAs are: Metropolitan Statistical Areas, based on urbanized areas of 50,000 or more population, and Micropolitan Statistical Areas, based on urban clusters of at least 10,000 population but less than 50,000 population. The CBSAs for the 2010 Census are those defined by OMB and published in December 2009.

    Description

    The data includes the calculation results of the environmental noise mapping 2022 in the metropolitan areas in Bavaria. These are all cities in Bavaria with more than 100,000 inhabitants, i.e. Munich, Nuremberg, Augsburg, Fürth, Erlangen, Würzburg, Regensburg and Ingolstadt. In each metropolitan area, the noise from road traffic, from industrial and commercial facilities in accordance with Directive 2010/75/EU of 24.11.2010 on the integrated prevention and control of environmental pollution (Industrial Emissions Directive - IED Directive) and, where available, from tram and above-ground subway traffic recorded. The noise calculations are carried out in accordance with the "Calculation method for ambient noise from sources close to the ground (roads, railways, industry and commerce) (BUB)". The noise indices LDEN and LNight in dB(A) are used as a measure of general annoyance and as a measure of sleep disturbances. The level LDEN is an immission level averaged over 24 hours, which consists of the levels LDay, LEvening and LNight for the assessment times day (6:00 a.m. to 6:00 p.m.), evening (6:00 p.m. to 10:00 p.m.) and night (22 :00-6:00 a.m.) is determined. The increased sensitivity to noise during these times is taken into account by weighting factors of 5 dB(A) for the four-hour evening time and 10 dB(A) for the eight-hour night time. The layer describes the noise pollution from industrial plants in the metropolitan area expressed by the noise index LNight according to the EC environmental noise directive. According to the directive, only IED systems are considered.

    Description

    Census data are disseminated for a wide range of geographic areas ranging from the national level down to the highly detailed enumeration area (EA) level. Reference maps depict the boundaries of these geographic areas and help users put the census data in a spatial context. The metropolitan hierarchy includes census metropolitan areas (CMA), census agglomerations (CA), consolidated CMAs, consolidated CAs, primary CMAs, primary CAs, urban core, urban fringe and rural fringe, census subdivisions (CSD) and census tracts (CT). The Census Metropolitan Areas, Census Agglomerations and Census Tracts Reference Map Series presents CTs for CMAs and traded CAs. Maps are not produced for CAs that are not tracted. CT names and boundaries are shown on all the maps.

    Description

    The 2023 cartographic boundary shapefiles 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. Metropolitan and Micropolitan Statistical Areas are together termed Core Based Statistical Areas (CBSAs) and are defined by the Office of Management and Budget (OMB) and consist of the county or counties or equivalent entities associated with at least one urban core of at least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with the counties containing the core. Categories of CBSAs are: Metropolitan Statistical Areas, based on urban areas of 50,000 or more population; and Micropolitan Statistical Areas, based on urban areas of at least 10,000 population but less than 50,000 population. The generalized boundaries in this file are based on those defined by OMB based on the 2020 Census and published in 2023.

    Description

    This web map shows annual Gross Domestic Product (GDP) by state and metro area in the USA for 2015. Clicking on the map reveals information about how the GDP has changed over time since 2001.The overlay of metro areas over states helps to put emphasis on where the country's GDP is coming from. The darkest green states produce the largest amount of GDP, and the largest circles show which major metropolitan areas contribute the most GDP within each state. Data is from the US Bureau of Economic Analysis and was downloaded from here. The state boundaries are generalized 2010 state boundaries from the Census Bureau's 2010 MAF/TIGER database. Note-- NAICS Industry detail is based on the 2007 North American Industry Classification System (NAICS).

    Description

    The month's Map of the Month examines an issue of housing policy not often discussed: how big are the houses that get built? The map depicts metropolitan areas in the United States with both the largest and smallest units. As you can see, the San Francisco-Oakland urbanized area is on the small end of the scale.

Description

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Metropolitan Divisions subdivide a Metropolitan Statistical Area containing a single core urban area that has a population of at least 2.5 million to form smaller groupings of counties or equivalent entities. Not all Metropolitan Statistical Areas with urban areas of this size will contain Metropolitan Divisions. Metropolitan Division are defined by the Office of Management and Budget (OMB) and consist of one or more main counties or equivalent entities that represent an employment center or centers, plus adjacent counties associated with the main county or counties through commuting ties. Because Metropolitan Divisions represent subdivisions of larger Metropolitan Statistical Areas, it is not appropriate to rank or compare Metropolitan Divisions with Metropolitan and Micropolitan Statistical Areas. The Metropolitan Divisions boundaries are those defined by OMB based on the 2010 Census, published in 2013, and updated in 2017.
