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.

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 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.

2018 U.S. & World Population

.. Welcome to 2018 .. how the U.S. and world are changing …

The Census Bureau estimates the U.S. population is 326,971,407 as of January 1, 2018. This represents an increase of 2,314,238, or 0.71 percent, from New Year’s Day 2017. Since Census Day (April 1) 2010, the population has grown by 18,225,587, or 5.90 percent.

In January 2018, the U.S. is expected to experience one birth every 8 seconds and one death every 10 seconds. Meanwhile, net international migration is expected to add one person to the U.S. population every 29 seconds. The combination of births, deaths and net international migration will increase the U.S. population by one person every 18 seconds.

The world population on January 1, 2018 is estimated to be 7,444,443,881. The world has experienced a population increase of 78,521,283, or 1.07 percent, from New Year’s Day 2017. During January 2018, 4.3 births and 1.8 deaths are expected worldwide every second.

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.
