The Urban Areas dataset was compiled on January 01, 2025 from the U.S. Department of Commerce, U.S. Census Bureau, Geography Division and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This resource is a member of a series. 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) System (MTS). The MTS 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. After each decennial census, the Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the urban footprint. There are 2,644 Urban Areas (UAs) in this data release with either a minimum population of 5,000 or a housing unit count of 2,000 units. Each urban area is identified by a five-character numeric census code that may contain leading zeros. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529088

The Census Bureau released revised delineations for urban areas on December 29, 2022. The new criteria (contained in this Federal Register Notice) is based primarily on housing unit density measured at the census block level. The minimum qualifying threshold for inclusion as an urban area is an area that contains at least 2,000 housing units or has a population of at least 5,000 persons. It also eliminates the classification of areas as “urban clusters/urbanized areas”. This represents a change from 2010, where urban areas were defined as areas consisting of 50,000 people or more and urban clusters consisted of at least 2,500 people but less than 50,000 people with at least 1,500 people living outside of group quarters. Due to the new population thresholds for urban areas, 36 urban clusters in California are no longer considered urban areas, leaving California with 193 urban areas after the new criteria was implemented.

The State of California experienced an increase of 1,885,884 in the total urban population, or 5.3%. However, the total urban area population as a percentage of the California total population went down from 95% to 94.2%. For more information about the mapped data, download the Excel spreadsheet here.

Please note that some of the 2020 urban areas have different names or additional place names as a result of the inclusion of housing unit counts as secondary naming criteria.

Please note there are four urban areas that cross state boundaries in Arizona and Nevada. For 2010, only the parts within California are displayed on the map; however, the population and housing estimates represent the entirety of the urban areas. For 2020, the population and housing unit estimates pertains to the areas within California only.

Data for this web application was derived from the 2010 and 2020 Censuses (2010 and 2020 Census Blocks, 2020 Urban Areas, and Counties) and the 2016-2020 American Community Survey (2010 -Urban Areas) and can be found at data.census.gov.

In 2023, the metropolitan area of New York-Newark-Jersey City had the biggest population in the United States. Based on annual estimates from the census, the metropolitan area had around 19.5 million inhabitants, which was a slight decrease from the previous year. The Los Angeles and Chicago metro areas rounded out the top three. What is a metropolitan statistical area? In general, a metropolitan statistical area (MSA) is a core urbanized area with a population of at least 50,000 inhabitants – the smallest MSA is Carson City, with an estimated population of nearly 56,000. The urban area is made bigger by adjacent communities that are socially and economically linked to the center. MSAs are particularly helpful in tracking demographic change over time in large communities and allow officials to see where the largest pockets of inhabitants are in the country. How many MSAs are in the United States? There were 421 metropolitan statistical areas across the U.S. as of July 2021. The largest city in each MSA is designated the principal city and will be the first name in the title. An additional two cities can be added to the title, and these will be listed in population order based on the most recent census. So, in the example of New York-Newark-Jersey City, New York has the highest population, while Jersey City has the lowest. The U.S. Census Bureau conducts an official population count every ten years, and the new count is expected to be announced by the end of 2030.

Data on European cities were collected in the Urban Audit and in the Large City Audit project. The projects' ultimate goal is to contribute towards the improvement of the quality of urban life: it supports the exchange of experience among European cities; it helps to identify best practices; it facilitates benchmarking at the European level and provides information on the dynamics within the cities and with their surroundings.

At the city level, the Urban Audit contains more than 130 variables and more than 50 indicators. These indicators are derived from the variables collected by the European Statistical System.

The data is published in 20 tables within 2 main groups, plus a perception survey table:

Although the American Community Survey (ACS) produces population, demographic and housing unit estimates, it is the Census Bureau's Population Estimates Program that produces and disseminates the official estimates of the population for the nation, states, counties, cities, and towns and estimates of housing units for states and counties.

Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted roughly as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see ACS Technical Documentation https://www.census.gov/programs-surveys/acs/technical-documentation.html). The effect of nonsampling error is not represented in these tables.

2007 marked the first year where more of the world's population lived in an urban setting than a rural setting. In 1960, roughly a third of the world lived in an urban setting; it is expected that this figure will reach two thirds by 2050. Urbanization is a fairly new phenomenon; for the vast majority of human history, fewer than five percent of the world lived in urban areas, due to the dependency on subsistence agriculture. Advancements in agricultural practices and technology then coincided with the beginning of the industrial revolution in Europe in the late 19th century, which resulted in waves of urbanization to meet the demands of emerging manufacturing industries. This trend was replicated across the rest of the world as it industrialized over the following two centuries, and the most significant increase coincided with the industrialization of the most populous countries in Asia. In more developed economies, urbanization remains high even as economies de-industrialize, due to a variety of factors such as housing availability, labor demands in service industries, and social trends.

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. After each decennial census, the Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the urban footprint. There are 2,644 Urban Areas (UAs) in this data release with either a minimum population of 5,000 or a housing unit count of 2,000 units. Each urban area is identified by a 5-character numeric census code that may contain leading zeroes. This file includes revisions made to the 2020 Census New Orleans, LA Urban Area where the territory originally delineated as the 2020 Census Laplace--Lutcher--Gramercy, LA Urban Area was combined with the 2020 Census New Orleans, LA Urban Area to form the current New Orleans, LA Urban Area. This file includes revisions made to the 2020 Census Atlanta, GA Urban Area and Gainesville, GA Urban Area, where some urban territory originally designated to the Gainesville, GA Urban Area was reassigned to the Atlanta, GA Urban Area.

After the 2020 Census, there are three key changes to the Census Bureau’s urban area concept and criteria:We increased the minimum population threshold to qualify as urban from 2,500 to 5,000, and we added an alternative: instead of qualifying based on population size, areas can now qualify based on a minimum housing unit threshold.We now use housing unit density instead of population density.We no longer distinguish between different types of urban areas.The first two changes reflect a general shift by the Census Bureau toward using housing units to measure urbanization and identify qualifying urban areas.

About this dataset

Each urban area is uniquely identified by a 5-character numeric census code that may contain leading zeroes as necessary. The dataset comprises several key attributes such as the name of the urban area (represented by multiple columns), legal/statistical area description, MAF/TIGER feature class code for classification purposes (MTFCC10), urban area type code (UATYP10), functional status indicating its operational characteristics (FUNCSTAT10), and geographic coordinates specifying the latitude and longitude of the interior point of each urban area.

Additional information available includes the land area in square meters (ALAND10) which denotes the extent of developed territory within an urban zone. Similarly, water areas associated with each urban area are provided as well in square meters measurement (AWATER10). Furthermore, shape length is included to describe the total length of an individual's shape or outline within an urban region while shape area signifies its overall spatial extent.

How to use the dataset

Here is a step-by-step guide on how to effectively use this dataset:

• Import the Data: Load the dataset into your preferred tool or programming language for data analysis. Popular options include Python with libraries like pandas or R with packages like tidyr.

• Explore the Columns: Familiarize yourself with the available columns in the dataset. Here are some important ones:

  • NAME10: The name of each urban area.
  • NAMELSAD10: The name and legal/statistical area description of each urban area.
  • UACE10: A 5-character numeric census code that uniquely identifies each urban area.
  • ALAND10: The land area of each urban area in square meters.
  • AWATER10: The water area of each urban area in square meters.
  • FUNCSTAT10: The functional status of each urban area.
  • INTPTLAT10 and INTPTLON10: The latitude and longitude coordinates of the interior point of each urban area.

• Understand Urban Area Types: The dataset distinguishes between two types of urban areas:

  a) Urbanized Areas (UAs): These areas contain 50,000 or more people.

  b) Urban Clusters (UCs): These areas contain at least 2,500 people but fewer than 50,000 people. (Except in the U.S. Virgin Islands and Guam, which may have urban clusters with populations greater than 50,000).

  The column UATYP10 provides the urban area type code for each entry.

• Analyze Functional Status: Explore the FUNCSTAT10 column to understand the functional status of each urban area. This information indicates whether an area is deemed functional for residential, commercial, or other non-residential purposes.

• Visualize Geographic Data: Util

Research Ideas

• Urban Planning Analysis: This dataset can be used to analyze and compare different urban areas based on their land area, water area, population density, and functional status. It can provide valuable insights for urban planners in terms of designing infrastructure, allocating resources, and making informed decisions to ensure sustainable development.
• Demographic Research: Researchers studying population trends and demographics can utilize this dataset to understand the growth, distribution, and characteristics of urban areas over time. By analyzing the population size and density of different urban areas, they can identify patterns of urbanization and assess the impact of policies or events on urban populations.
• Environmental Impact Assessment: The land area and water area information in this dataset can be used to assess the environmental impact of urban areas. Researchers or environmentalists can analyze the proportion of green spaces versus built-up areas within each urban area to evaluate levels of air pollution, biodiversity loss, or potential for implementing sustainable practices like rooftop gardens or rainwater harvesting systems

NJDOT has revised the New Jersey urban area based upon the 2020 U.S. Census urban area boundaries. The U.S. Census defines an Urbanized Area as any area with a population >= 5,000. Under the 2020 Urban Area definition, Urban Clusters are no longer a classification. FHWA, however, has slightly different criteria for what defines an urban area. Under FHWA, an Urban Area is >= 5,000, with Small Urban Areas 5,000-49,999 and Urbanized Areas >= 50,000. NJDOT followed the FHWA urban area definitions for this urban area update. To perform this update, NJDOT used the 2020 US Census urban areas greater than 5,000 in population. Since census urban area boundaries are based upon census block boundaries, which can be irregular, NJDOT extended outward the urban area ("smoothed") to the nearest road, stream, political boundary, or manmade feature. When a roadway is used as the adjusted boundary, the following buffers will be applied to include the right of way of the roadway: 50’ from undivided roadway centerlines (single centerline) and 80’ from divided roadway centerlines (dual centerline). Where there was no obvious boundary to smooth to, the census boundary was retained. NJDOT also expanded the urban area to include any densely developed areas not included in the 2020 census urban areas. The urban area update underwent a thorough public review and comment period. Representatives from NJDOT and the 3 metropolitan planning organizations (NJTPA, SJTPO, and DVRPC) met during various phases of the project to review the updated urban area. All comments were logged into an Urban Area Comment Tracking Form, and an official NJDOT response was provided for each comment. Further revisions were made to the urban area based upon comments from FHWA. These revisions were limited in scope and consisted of the following: 1) Smoothed the urban boundary outward at water boundaries: 1000’ from corporate boundary / shoreline for coastal areas and 500’ from corporate boundary / shoreline for bay areas. 2) Utilize Census State Boundary for the state boundary except for coastal boundaries.
