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.

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.

Personal Economic Well-Being

.. examining characteristics, patterns and change in personal economic well-being; learning about what per capita personal income by county tells us. Per capita personal income (PCPI) is the best single measure of personal economic well-being. PCPI differs American Community Survey (ACS) measure of per capita income, median household income and similar income measures as PCPI includes non-monetary income .. PCPI provides a more comprehensive measure. This post provides an update focused on new data released November 2022, county level personal income time series data starting in 1969.

Importance of these Data
How is the regional economy doing? How is it trending? What policies might be changed to improve personal economic well-being? Answers to these and similar questions are why knowing about personal income and its derivation, components is important — to residents, businesses and governments. While median household income is often considered the best measure of buying power for an area, it is not the best measure of personal or household economic well-being. PCPI and the Regional Economic Information System provides insights and answers to these questions.

U.S. Change in PCPI
In U.S. metropolitan areas, PCPI increased 7.3 percent in 2021, up from 6.0 percent in 2020. In U.S. nonmetropolitan areas, PCPI increased 7.5 percent, down from 7.9 percent.

Naturally Occurring Retirement Communities in Path of Hurricane Ian

.. 25.8 million U.S. households had a head of household age 65 years or over in 2010; 22.1% of total households. 3.1 million households with head of household 65 years or over were located in 10,201 “naturally occurring retirement communities” (NORCs) — areas where the percent of head of household age 65 or over is 40 percent or more. Has the number of NORCs tripled by now? Where and how much .. a next blog.

Here, we review Naturally Occurring Retirement Communities in the Path of Hurricane Ian by block group (BGs) in Lee County, FL … using VDA Web GIS. The same process can be applied to any area.

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.

Housing Price Index by ZIP Code – How Housing Markets are Trending

.. housing prices can impact residential investment and affect economic growth, business opportunities and the housing market. The Housing Price Index (HPI) is one measure of how housing prices are changing. The HPI by ZIP code, as reviewed here, is an index based on the year 2000=100. Changing trends in the HPI can used used the determine the relative costs of housing and change in housing valuation. Hosing prices, and the HPI, are only one part of determining how housing markets are trending. Other measures important to examine include building permits and new construction.

Examining Age/Gender Distributions with Population Pyramids

Population pyramids provide a data visualization often used in demographic analysis because they provide a condensed but powerful illustration of a population’s age distribution by gender. You can use the ChartGraphics tool to create population pyramids for the U.S., states, counties and other areas as reviewed in this section. For example, examine Census 2020 population by 5-year age group by gender for your area of interest.

A population pyramid is essentially two bar charts, one for the male population on the left and the other for the female population on the right. The base of the pyramid, or bottom of the chart, has the youngest population (ages 0-4) and the top has the oldest (ages 85 and older). The following pyramids illustrate how Orange County, CA has changed from 2000 to 2020.

Real Quarterly GDP Trends: State of the States

.. real gross domestic product (RGDP) decreased in 46 states and DC in 2022Q1, as real GDP for the nation decreased at an annual rate of 1.6 percent. The percent change in real GDP in 2022Q1 ranged from 1.2 percent in New Hampshire to 9.7 percent in Wyoming. Updated quarterly GDP estimates have only a 3-month lag from the reference date (e.g., 2022Q1) to access date (e.g. June 2022). Used as a time series, these data provide insights into recent economic change and prospective future change. The RGDP estimates are developed by sector, enabling an assessment of which and how sectors are contributing to change. While we look at all states in this post, California is used as an example. Examine your state(s) of interest using the tools and data described here.

See this companion video illustrating some aspects of using VDA Web GIS with the state quarterly GDP.

Looking Ahead; Updates
New quarterly GDP by state estimates for 2022Q2 and revised annual GDP by state estimates for 2017 to 2021 and will be released on September 30, 2022.

About GDP and Measurement
State GDP estimates are updated quarterly by the U.S. Bureau of Economic Analysis (BEA). The following terminology may be a useful reference.
Gross domestic product (GDP) by state is the market value of goods and services produced by the labor and property located in a state. GDP by state is the state counterpart of the nation’s gross domestic product, the most comprehensive measure of U.S. economic activity.
Current-dollar statistics are valued in the prices of the period when the transactions occurred—that is, at “market value.” Also referred to as “nominal GDP” or “current-price GDP.”
Real GDP values are inflation-adjusted statistics, these values exclude the effects of price changes.
State GDP is the lowest geographic level for which quarterly estimates of GDP are produced by BEA.
Seasonal adjustment and annual rates. Quarterly values are expressed at seasonally adjusted annual rates.
Quantities and prices. Quantities, or “real” measures, are expressed as index numbers with a specified reference year equal to 100 (currently 2012). Quantity indexes are calculated using a Fisher-chained weighted formula that incorporates weights from two adjacent periods (quarters for quarterly data and annuals for annual data). “Real” dollar series are calculated by multiplying the quantity index by the current dollar value in the reference year and then dividing by 100. Percent changes calculated from chained-dollar levels and quantity indexes are conceptually the same. Chained-dollar values are not additive, because the relative weights for a given period differ from those of the reference year.
Chained-dollar values of GDP by state are derived by applying national chain-type price indexes to the current dollar values of GDP by state for the 21 North American Industry Classification System-based industry sectors. The chain-type index formula that is used in the national accounts is then used to calculate the values of total real GDP by state and real GDP by state at more aggregated industry levels. Real GDP by state may reflect a substantial volume of output that is sold to other states and countries. To the extent that a state’s output is produced and sold in national markets at relatively uniform prices (or sold locally at national prices), real GDP by state captures the differences across states that reflect the relative differences in the mix of goods and services that the states produce. However, real GDP by state does not capture geographic differences in the prices of goods and services that are produced and sold locally.

Block Group Data & Demographic Analysis

.. location demographics .. find a block group (BG) based on an address using VDA Web GIS. Determine the BG code. See the BG map in context of other BGs, the topography, other geographies. Create a profile for a selected BG (2010 or 2020). View U.S. national scope BGs in a table/grid; sort on selected demographics. Query for BGs meeting certain criteria like median household income. Nothing to install, use your Web browser. No cost. Start VDA Web GIS here. See map example below where VDA is used to examine BGs in the Los Angeles area. Need help? Click the chat/message us button on the VDA web page.

Block Groups are the smallest geography areas for which data from the American Community Survey (ACS) are tabulated and cover the U.S. wall-to-wall. The popularity, importance, of block groups is their small area granualarity. While the decennial census provides demographics at the census block level, BGs are the smallest geographic area where richer demographics (like median household income) are available. BGs are also important as demographics are developed annually via the ACS 5-year estimates. The ACS 2019 block groups were based on Census 2010 geography. ACS 2020 block groups are based on Census 2020 geography. Many 2020 BG geographic areas differ from 2010 BG geographic areas especially in suburban and areas experiencing demographic change. 2010 and 2020 BGs often differ in both the geometry, earth surface coverage, and the geocode, the 12 character shorthand code/name. Since the geography differs, demographics for 2010 and 2020 BGs are often not directly comparable.

Block Group Geography
Block group geography is defined by the Census Bureau and generally non-changing for the decade, good for longitudinal demographic analysis throughout the 2020s. BGs are comprised of a set of census blocks and a part of (nest within) census tracts. See 2020 BG final criteria. 2020 BG geography is represented by shapefiles developed by the Census Bureau. Download the zip file containing the 2020 smoothed national scope BG boundaries here. Expanding that zip file, add the BG shapefile to a CV XE GIS project to view and use the BG geography (no subject matter included).

About Block Group 060372653011
The 2020 block group 06-037-265301-1 is highlighted in the above graphic. It has a 12 character geocode 06 (California) 037 (Los Angeles County) 256301 (2020 census tract) and block group 1 (2020 block group – unique code within tract). This block group has a high concentration of population who live in dorms (group quarters, noninstitutional) resulting in a high population to housing unit ratio. View the Census 2020 profile for this BG by clicking on this BG .. the profile is shown in the lower left panel. Click the HTML button to view the profile as an HTML page.

Block Group Demographics
The geometry of 2020 BGs is designed for population threshold of 600 to 3,000 population but might actually have a much larger population. Using 2010 BGs, the two primary sources of demographics are Census 2010 and the annual ACS 5-year estimates through 2019. Using 2020 BGs, the two primary sources of demographics are Census 2020 and annual ACS 5-year estimates starting with ACS 2020 (release date March 17, 2022). Many organizations use BG geography and demographics with their own programs, such as the Environmental Justice program of EPA.

Using DEDE
Use the Demographic-Economic Data Explorer (DEDE) to create custom 2010 or 2020 BG demographic data profiles or datasets from the decennial census or annual ACS programs. DEDE enables you to select from any of the thousands of BG demographics tabulated in the Census 2010, Census 2020 or any of the annual ACS statistical programs.

Using VDA Web GIS
