The New Urban Geography

.. the nation’s urban population increased by 6.4% between 2010 and 2020 based on 2020 Census data and a change in the way urban areas are defined. As a result of these changes, 1,140 areas containing approximately 4.2 million people, classified as urban in 2010 are now rural. See more about the 2020 urban/rural geography/population. See more about the urban population.

Patterns of the New Urban Geography

As of 2020, there are 2,613 Urban Areas in the U.S. with a combined Census 2020 population of 265,149,027 (80%). The remaining area is defined as rural with Census 2020 population of 66,300,254 (20%).
  • Use this interactive table to view, sort urban areas.
  • Use this interactive table to view, sort states by 2010/2020 urban/rural.

These Federal designated urban areas are comprised of densely settled core of census blocks that meet minimum housing unit density and/or population density requirements. This includes adjacent territory containing non-residential urban land uses. To qualify as an urban area, the territory identified according to criteria must encompass at least 2,000 housing units or a population of at least 5,000. Rural encompasses all population, housing, and territory not included within urban areas.

Importance of Urban/Rural Designations
Data users and researchers interested in analyzing data for urban and rural population and housing use urban area geostatistical data routinely updated by statistical agencies. Analysts use urban area data to study patterns of urbanization, suburban growth and development, and urban/rural land area change.

Larger Urban Areas form the nucleus of Core-Based Statistical Areas (metros). Many metro areas (one or more contiguous counties) contain large rural areas even though some consider metros as large cities. Importantly, they are not the same.

Various federal and state agencies use urban and rural definitions as the basis for their own urban and rural definitions and settlement classifications for use in tabulating and presenting statistical data. The National Center for Education Statistics uses the urban area definitions in its locale codes classification. The U.S. Department of Agriculture uses the urban area classification as the basis for various urban and rural classifications used to analyze and report on demographic and economic patterns in rural areas.

Other government agencies use Urban Area designations to determine program eligibility and in their funding formulas. The Federal Highways Administration uses urban areas of 50,000 or more population to establish Metropolitan Planning Organizations. For rural health programs, a clinic qualifies as a rural health clinic if it is located outside the boundaries of any urban area.

Population Living Alone & Age 65 Years and Over

.. how many people are living alone in your community, neighborhood? How does this population impact the community? What are their special needs? How does this population vary by area and population group? There were 37.9 million one-person households, 29% of all U.S. households in 2022. In 1960, single-person households represented only 13% of all households. These estimates are based on the 2022 Current Population Survey (CPS). Moving forward, the number of one-person households, people living alone, will increase at the rate of one million or more per year. People in households exclude people living in group quarters. This post examines patterns of people living alone with focus on people living alone age 65 year and over and distribution by small area geography.

While the CPS data provide a current snapshot of the number of people living alone, we have to use data from the American Community Survey to obtain data for smaller area geography like counties and census tracts.

Population Living Alone by Census Tract –Visual Data Analytics

Examine the Data in More Detail
As noted in this related New York Times story, nearly 26 million Americans 50 or older now live alone, up from 15 million in 2000. Older people have always been more likely than others to live by themselves makes up a bigger share of the population than at any time in the nation’s history. The trend has also been driven by deep changes in attitudes surrounding gender and marriage. People 50-plus today are more likely than earlier generations to be divorced, separated or never married. Similar ACS data as used to develop the graphics shown above are available by race/origin. These data are based on the ACS 2020 data; the same scope of data will be available from ACS 2021 to be released in December 2022.

Examining Majority-Minority Population by Census Tract

.. a geographic area, such as a census tract or county, has a majority-minority (MM) population when the percent of the population less White, NonHispanic population is more than 50-percent or more of the total population. This section examines patterns of MM by 2020 census tract in the Houston, TX area using the VDA Web GIS (VDA). You can use VDA to examine patterns of MM by tract for areas of interest. All you need is a Web browser and Internet.

MM Tracts in the Houston Area
The following graphic shows patterns of the MM by tract in the Houston metro developed with VDA. The map shows tracts having more than 50% MM population with a red/salmon color. Tracts having 50% or less MM population are shown in blue/green/yellow. Harris County, TX has 1,115 2020 census tracts; 854 of these tracts have a MM population. See the partial list of those tracts by tract code and %MM in the table below the map. A query was used to determine the number of tracts meeting a criteria and sorted in descending order by %MM.

See this VDA Guide section for a step-by-step description
of how you can develop this or a similar view/analysis.

Percent Majority-Minority is a demographic attribute/measure for a geographic area. Like population density or percent population of a certain age, %MM can provide insights for stakeholders or analysts.

Arizona’s Shifting Demographics

Census 2020 Arizona Demographics
The Arizona July 1, 2020 Census model-based population estimate of 7,421,401 compares to the Census 2020 population count of 7,151,502 people. The difference of -269,899 between the 2020 estimate and the 2020 count can be explained by several factors. First, the estimate is for a point in time that is three months later that the Census. There will be a tendency of the Census Bureau to adjust the Joly 1, 2020 population estimate to conform to the Census 2020 value. The July 1, 2020 estimate will likely be adjusted to reflect this change when the July 1, 2021 estimates are released April/May of 2022.

The 2020 population estimate is determined using a component method. The 2020 population estimate is the sum of the 2019 population estimate (7,291,843 for Arizona) and each of the following for the period July 1, 2019 through June 30, 2020 …
plus births (AZ 81,451)
less deaths (AZ 66,385)
plus international migration (AZ 9,272)
plus domestic migration (AZ 105,435)
plus an estimation residual (AZ -214)

Any one or a combination of these 6 estimate based values could be wrong, or the Census 2020 value could be wrong. It is likely a combination of all of these factors.

The remainder of this section is based on Census Bureau model-based estimates, released April 26, 2021. See more about these data for all U.S. counties in the Demographics 2060 section where Arizona demographic projections can be examined.

Visualizing Arizona Demographic Change

Looking Ahead
More geographically detailed data (counties for example) based Census 2020 (August 2021) will reveal much starker percentage differences between the 2020 estimates versus Census results. The ProximityOne annual estimates and projections to 2060 are developed using two basic series (and variation among those (low, base, high): Census 2020 based series and 2020 estimates series.

Monthly New Authorized Residential Construction
ProximityOne maintains a national monthly time-series database providing access to new authorized residential construction data.  The table presented below summaries key subject matter items available at the city and county level.. These data are one of eleven leading economic indicators. The housing market is often one of the first economic sectors to expand or contract when economic conditions improve or decline. With only a one month lag from reference data to availability date, these measures are early indicators of housing market change. This change typically leads to other types of economic change.
