How & Why County Demographics are Changing

.. the pandemic impact on population change remains in flux. For many counties it will impact each component of population change: births, deaths and migration. The magnitude and duration of the impact on each component will vary by county and become more measurable in the months ahead. The “How & Why County Demographics are Changing” will be updated later in 2020.

Here we look at population and components of change by county for the period 2010 to 2019 .. tools and data to examine how the U.S. by county population is changing. These latest 2019 estimates were released this spring. See more in the related web section.

Examining Population Components of Change
Population change can be examined in terms of components of change. There are three components of change: births, deaths, and migration. The change in the population from births and deaths is often combined and referred to as natural increase or natural change. Populations grow or shrink depending on if they gain people faster than they lose them. Examining a county’s unique combination of natural change and migration provides insights into why its population is changing and how quickly the change is occurring. The above graphic shows these relationships.

U.S. & World Population, 2020

.. changing demographics .. the U.S. population stands 330,222,422 on January 1, 2020 .. an increase of 1,991,085, 0.61%, from a year ago. The April 1, 2010 Census population was 308,758,105.

 
In January 2020, the United States experiences one birth every eight seconds and one death every 11 seconds.

.. the net international migration adds one person to the U.S. population every 34 seconds. The combination of births, deaths and net international migration will increase the U.S. population by one person every 19 seconds.

The projected world population on January 1, 2020, is 7,621,018,958, an increase of 77,684,873, or 1.03%, from a year earlier. During January 2020, 4.3 births and 1.9 deaths are expected worldwide every second.

Kickoff of Census-Sourced Vintage 2019 Population Estimates Program
Starting in December of each year, the Census Bureau develops official population estimates for July of that year. In 2020, the Bureau will progressively release population estimates with greater subject matter detail for more detailed subnational geography. These model-based estimates will be completed in June 2020 for incorporated places.

The July 2019 estimates for the U.S. and states were just released in December 2019. These estimates reflect that the natural Increase dropped below 1 million for the first time in decades due to fewer births and more deaths.

The July 1, 2019, U.S. population estimate is 328,239,523, growing by 0.5% between 2018 and 2019, or 1,552,022 people. Annual growth peaked at 0.73% this decade in the period between 2014 and 2015. The growth between 2018 and 2019 is a continuation of a multiyear slowdown since that period. More detail on U.S. and state trends will be reviewed in a subsequent post.

Click graphic for larger view; expand browser window for best quality view. What are the insights from these data, this view? How are the insights developed? Their application and use creates the value. .

– U.S. by state interactive table.
– U.S. by metro interactive table.
– U.S. by county interactive table.
– U.S. by city interactive table.
– U.S. by census tract interactive table.

An example of the “tip of the iceberg,” the above model-based demographic data have been developed for use in developing the more detailed American Community Survey annual demographic data — annual updates on demographics down to the block group level of geography. ~217,000 areas covering the U.S. wall-to-wall.

Valuation of Demographic Insights
Having the required demographic data is needed before value can be assigned to their use. It’s really not possible to value demographic data or insights on a financial basis alone. But here are some considerations. One way to assign a value to demographic data is on the cost basis. The above data have been developed by the Census Bureau. But they are not free to develop — the costs for the Federal programs to produce them and the cost for others providing access to the data and using them.

These demographic data enable an unestimable number of studies that result in an unestimable set of decisions in the private and public sector. Many evolve into useful insights, but certainly not all.

Census 2020 is will cost in excess of $16 billion. That’s just to get the data out there. The value of these demographic data have to be in the many trillions or much more. Plus, these demographics enable things that can be done that cannot be done with any other set of demographic data. This “uniqueness thread” runs through many demographic data programs. What is the value of being able to apportion Congress, state legislatures and thousands of other governmental bodies?

How to assign value to one decision based substantially on geodemographics?

What about the byproducts? Census 2020 relies heavily on the Census produced (with the indispensable involvement of regional governments) TIGER/Line geographic database. In essence, we have a demographic data program producing a geographic database. It can be argued that the public use TIGER database is the most valuable past of the decennial census. TIGER provides the digital map database undergirding all widely used mapservers such as Google maps and Bing. It provides the unique and near comprehensive set of standardized geographic data going down to the intersection-to-intersection street segment. It enables a near infinite set of Geographic Information System (GIS) applications.

The above addresses mainly matters of demographic data developed on a national scale. All businesses deal in their own demographics daily. This set of demographic data minimally includes staff and related consultants, etc. plus prospects and clients/customers. Many businesses do not take advantage of the potential benefits of having these data. They can often do more to use their own data, and data of competitors and about the market, to develop improved plans to meet their goals.

Examining Economic Well-Being by Metro

.. examining the state of economic well-being: 2008-2017 .. expanding insights through data analytics .. tools and data to examine how and where the U.S. by metropolitan area real personal income is changing.  Real per capita personal income (RPCPI) is the best single measure of personal economic-well being. By examining RPCPI trends over a period, stakeholders can better determine if the area in improving, stable or declining. Still, RPCPI is but one important measure among many others, such as the Regional Price Parities (RPP). Use the interactive table, and related GIS tools, to examine these and other real personal income measures for the Nation’s 383 Metropolitan Statistical Areas (MSAs). See related Web section for more detail.

Based on data released by the Bureau of Economic Analysis in May 2019, see about in statistical release dates, real state personal income grew 2.6 percent in 2017, after increasing 1.5 percent in 2016. Real state personal income is a state’s current-dollar personal income adjusted by the state’s regional price parity and the national personal consumption expenditures price index. Across metropolitan areas, the percent change ranged from 14.8 percent in Midland, MI to -5.9 percent in Enid, OK

Visually Examining Patterns of Economic Well-Being
Geographic Information Systems (GIS) tools provide a powerful to explore these data. The following graphic shows a view of real per capita personal income (RPCPI), 2017, for Texas MSAs.

Each row provides a 2008-17 annual time series for four items (and derived items): real per capita personal income, regional prices parities-all items, total real personal income, implicit regional price deflator.

The following graphic shows these areas ranked on RPCPI in 2017. See rightmost column rank. Click graphic for larger view. Midland, TX MSA has the 4th highest 2017 RPCPI (shown in blue; also shown in blue in the map graphic above). But … that metro experienced a decrease of 12.1 percent over the period 2010-2017 .. and down from a high RPCPI of $115,069 in 2014. The dynamics of the oil industry!

State of the States: 2018 Population & Components of Change

.. Welcome to 2019 .. how the U.S., states and world population are changing … the Census Bureau estimates the U.S. population is 328,231,337 as of January 1, 2019. This represents an increase of 2,013,241, or 0.62 percent, from New Year’s Day 2018 (326,218,096). The population as of Census Day (April 1) 2010, was 308,745,538 and has grown by 19,485,799, or 6.31 percent.

New 2018 Vintage Metropolitan Areas

.. new, September 14, 2018 vintage, Core-Based Statistical Area (CBSA) delineations have been released by the U.S. Office of Management and Budget (OMB).  Among other things, the new delineations specify which counties are included in each CBSA.  CBSAs. an OMB standards term, are metropolitan areas comprised of Metropolitan Statistical Areas (now 384 MSAs in the U.S.) and Micropolitan Statistical Areas (now 542 MISAs in the U.S.).

How Metros Change Geographically
The following graphic, focused on the Charlotte, NC-SC MSA region, illustrates how MSAs are changing. 2017 vintage MSAs are shown with bold green boundary, yellow fill pattern. Cross-hatched areas are 2018 vintage MSA counties. As of the 2018 vintage, note that …
• Anson County, NC (to right of pointer) has been added to the Charlotte, NC-SC MSA.
• Union County, SC has been removed from the Spartanburg, SC MSA.
• Harnett County, NC has been added to the Fayetteville, NC MSA.

— graphic developed using CV XE GIS software and related GIS project.

What About My MSAs of Interest?
See detailed information about the 2018 vintage CBSAs/MSAs and their component counties at http://proximityone.com/cbsa2018.htm.

Impact of the 2018 Delineations
The new delineations take place immediately and have numerous impacts.  Going forward, Federal statistical agencies will develop statistics and use the new names and geocodes as set forth in the new delineations (most names and geocodes remain the same).  For CBSAs affected, which are numerous, this will result in challenges for longitudinal analyses where consistently defined geography over time is required.  The total 2017 official population estimates are affected for three of the largest 10 CBSAs using the 2018 delineations compared to the 2017 delineations.  More immediately, it may become confusing whether the 2018, 2017, 2015, or an earlier vintage CBSA geography is being referenced.  On a positive note, the 2018 vintage CBSAs are believed to best reflect the set of counties comprising a CBSA as an entity of highly related demographic-economic conditions.

Keeping Up-to-Date with Metro Demographic-Economic Data
Metropolitan Statistical Areas (MSAs/metros), comprised of one or more contiguous counties, are important for many reasons. Business, demographic and economic data for these 384 areas, each developed around an area of large population concentration, provide a “10,000 foot” view of these characteristics and how they are changing. As they are comprised of county groups, much of the subject matter data are also available for drill-down analysis at the county and sub-county levels. Metro boundaries change some over time … as more peripheral counties are added or removed depending on their demographic-economic affinity with central county(s).

Metros are an important part of the ProximityOne Situation & Outlook program. Metro demographic-economic estimates and projections are updated to reflect 2018 vintage metros. This includes all elements of the Census-sourced age-race/ethnicity-gender annual estimates and American Community Survey demographic-economic subject matter.

Designating Metros and Delineating Metro County Components
More detail … in consultation with Federal statistical agencies, OMB defines metropolitan statistical area boundaries. This section provides a summary of Metropolitan Statistical Areas (MSAs), and component Metropolitan Division and Counties/County Equivalents, as delineated in OMB Bulletin 18-04 issued September 14, 2018. These delineations take place immediately. This is a significant update affecting approximately 20-percent of previous MSA delineations (one or more county addition or removal).

Under the September 14, 2018 delineation, there are 938 Metropolitan Statistical Areas (MSAs) and Micropolitan Statistical Areas (MISAs) in the U.S. and Puerto Rico, collectively referred to as Core-Based Statistical Areas (CBSAs). There are 392 MSAs (384 in the U.S. and 8 in Puerto Rico). 11 MSAs contain a total of 31 Metropolitan Divisions. There are 546 MISAs (542 in the United States and 4 in Puerto Rico).

The 384 U.S. MSAs comprise 1,181 counties of total 3,142 U.S. counties. The total 2017 population of these metros was 280,468,904 of total 325,719,178 U.S. population (86.1%).

Examining State-to-State Geographic Mobility

.. tools, resources and insights to examine U.S. by state migration 2011-2017 and migration flows in 2016 .. this post is an excerpt from the more detailed Web page http://proximityone.com/statemigration.htm.

In examining future demographic trends, the most challenging component of change to project (develop data values into the future) is migration. Migration, comprised net domestic and net international migration, is a function of many factors whose cause and effect behavior can change year by year, and geographic area by area. While this section is focused on states, the same scope of data is available to the county and sub-county levels. In this section, U.S. by state migration is examined using two data sources: annual population and components of change model-based estimates (2010-2017 model-based estimates) and annual American Community Survey estimates (ACS 2016 estimates). While these Census Bureau programs are highly related, the migration data/subject matter differ some.

State Net Domestic Migration, 2011-2017

State OutMigration by Destination State
The model-based estimates, reviewed above, do not provide detail on state-to-state migration. Those data are provided by the related ACS 2016 estimates. Note that the ACS 2016 1-year estimates are for the calendar year 2016. From these data we can get the following migration detail … In 2016, there were an estimated 605,018 people who moved from a residence 1 year earlier, in a different state, to Florida. Florida experienced the largest number of movers (inflows) from other states among all states. 60,472 of these movers were from New York. See the interactive table in this section to examine similar characteristics for any state. These data are based on the 2016 ACS 1 year estimates. See about related data.

The American Community Survey (ACS) asks respondents age 1 year and over whether they lived in the same residence 1 year ago. For people who lived in a different residence, the location of their previous residence is collected. The state-to-state migration flows are created from tabulations of the current state (including the District of Columbia) of residence crossed by state of residence 1 year ago.

Examining County Migration: 2010-2016

.. tools and data to examine U.S. by county migration 2010 to 2016 … is the population moving away or into your counties of interest? What are the trends; what is causing the change? What are the characteristics of the population moving in and out? How might this impact your living environment and business?

The total net international migration among all counties 7/1/2010 – 7/1/2016 was 5,641,260, an annual average of 940,432. The sum of net domestic migration among counties is zero by definition, but domestic migration among counties varies radically by size and direction. This section is focused on U.S. by county migration from 2010 to 2016. Migration is one component of change used to develop population estimates. See more about county population estimates and components of change in this related Web section.

Examining Population Components of Change
– net migration and natural change
Population change can be examined in terms of components of change. There are three components of change: births, deaths, and migration. The change in the population from births and deaths is often combined and referred to as natural increase or natural change. Populations grow or shrink depending on if they gain people faster than they lose them. Examining a county’s unique combination of natural change and migration provides insights into why its population is changing and how quickly the change is occurring.

Using the Interactive Table
– examining migration by county
Use the interactive table to examine characters of counties by states, metro or peer group. The following graphic illustrates use of the interactive table to view net migration for the Houston metro by county. The net migration button was used to select only the net migration columns, FindCBSA button used to show only counties in this metro and the final step was to sort the resulting table on 2016 population.
