TIGER, TIGER/Line, and Census TIGER are registered trademarks of the Bureau of the Census. The Redistricting Census 2000 TIGER/Line files are an extract of selected geographic and cartographic information from the Census TIGER data base. The geographic coverage for a single TIGER/Line file is a county or statistical equivalent entity, with the coverage area based on January 1, 2000 legal boundaries. A complete set of Redistricting Census 2000 TIGER/Line files includes all counties and statistically equivalent entities in the United States and Puerto Rico. The Redistricting Census 2000 TIGER/Line files will not include files for the Island Areas. The Census TIGER data base represents a seamless national file with no overlaps or gaps between parts. However, each county-based TIGER/Line file is designed to stand alone as an independent data set or the files can be combined to cover the whole Nation. The Redistricting Census 2000 TIGER/Line files consist of line segments representing physical features and governmental and statistical boundaries. The Redistricting Census 2000 TIGER/Line files do NOT contain the ZIP Code Tabulation Areas (ZCTAs) and the address ranges are of approximately the same vintage as those appearing in the 1999 TIGER/Line files. That is, the Census Bureau is producing the Redistricting Census 2000 TIGER/Line files in advance of the computer processing that will ensure that the address ranges in the TIGER/Line files agree with the final Master Address File (MAF) used for tabulating Census 2000. The files contain information distributed over a series of record types for the spatial objects of a county. There are 17 record types, including the basic data record, the shape coordinate points, and geographic codes that can be used with appropriate software to prepare maps. Other geographic information contained in the files includes attributes such as feature identifiers/census feature class codes (CFCC) used to differentiate feature types, address ranges and ZIP Codes, codes for legal and statistical entities, latitude/longitude coordinates of linear and point features, landmark point features, area landmarks, key geographic features, and area boundaries. The Redistricting Census 2000 TIGER/Line data dictionary contains a complete list of all the fields in the 17 record types.

In 2020, **** percent of the North American population lived in urban areas. According to the projections, this figure is going to increase to ** percent in 2050. Across all major world regions, the level of urbanization is projected to be increasing in 2050.

The Historical Urban Population, 3700 BC - AD 2000, originally developed by the Yale School of Forestry & Environmental Studies, is the first spatially explicit global data set containing location and size of urban populations over the last 6,000 years. The data set was created by digitizing, transcribing, and geocoding historical, archaeological, and census-based urban population data. Each data point consists of a city name, latitude, longitude, year, population, and a reliability ranking to assess the geographic uncertainty of each data point. Despite spatial and temporal gaps, no other geocoded data set at this resolution exists. It can therefore be used to investigate long-term historical urbanization trends and patterns, evaluate the current era of urbanization, and build a richer record of urban population through history.

This 30-meter resolution raster data set of land cover for the conterminous United States ("NLCDep0306") was designed to describe conditions representative of the year 2000 and is the result of overlaying enhanced 1992 National Land Cover Data with 1990 and 2000 population data at the block group geographic level. Any area (excluding water, developed land, or wetlands) with population density of less than 1,000 people per square mile in 1990 and at least 1,000 people per square mile in 2000 was reclassified as "newly urbanized" land in the derivative product. Areas of water, developed land, or wetlands existing in the original national land-cover data set were preserved.

This data set supersedes the one called "Enhanced National Land Cover Data 1992 revised with 2000 population data to indicate urban development between 1992 and 2000" ("NLCDep0905") dated September 2005. NLCDep0905 coded any area having 2000 population density of at least 1,000 people per square mile as being ...

The United States Department of Housing and Urban Development had outlays of about 55.19 billion U.S. dollars in 2023. By 2029, the outlays of the Department of Housing and Urban Development are expected to increase to about 76.6 billion U.S. dollars.

Categories of urban land use represented in these data include: urban, suburban, rural and urbanized open land. The built-up area of the city is the area occupied by built-up pixels within the set of administrative boundaries defining the city. The urbanized open space consists of all fringe open spaces (including exterior open spaces) and all captured open spaces. These data are part of the Atlas of Urban Expansion.

Urban areas play a very important role in global climate change. There is an increasing interest in comprehending global urban areas with adequate geographic details for global climate change mitigation. Accurate and frequent urban area information is fundamental to comprehending urbanization processes and land use/cover change, as well as the impact of global climate and environmental change. Defense Meteorological Satellite Program/Operational Line Scan System (DMSP/OLS) night-light (NTL) imagery contributes powerfully to the spatial characterization of global cities, however, its application potential is seriously limited by its coarse resolution. In this paper, we generate annual Normalized Difference Urban Index (NDUI) to characterize global urban areas at a 30 m-resolution from 2000 to 2021 by combining Landsat-5,7,8 Normalized Difference Vegetation Index (NDVI) composites and DMSP/OLS NTL images on the Google Earth Engine (GEE) platform. With the capability to delineate urban boundaries and, at the same time, to present sufficient spatial details within urban areas, the NDUI datasets have the potential for urbanization studies at regional and global scales.
