U.S. House of Representatives 2020 Apportionment

.. Congressional Apportionment by State .. 2010 & projected 2020 state by state congressional seats.

What will the results of Census 2020 tell us us about how the House of Representatives will be reapportioned, state by state? This section examines scenarios which might occur based on state population projections. See related Web section http://proximityone.com/apportionment.htm for more detail and interactive table.

This section has been developed using
– 2020 apportionment population projections
    .. part of the ProximityOne Situation & Outlook (S&O)
– the reapportionment/redistricting feature of the CV XE GIS software
The 2020 population projections reflect anticipated change under one scenario. Those values are then used in the CV XE GIS reapportionment operation to compute the number of House seats shown in the related table.

Congressional apportionment is the process of dividing the 435 memberships, or seats, in the House of Representatives among the 50 states based on the population figures collected during the decennial census. The number of seats in the House has grown with the country. Congress sets the number in law and increased the number to 435 in 1913. The Constitution set the number of representatives at 65 from 1787 until the first Census of 1790, when it was increased to 105 members. More about apportionment.

Initial Census 2020 demographic data, the apportionment data, will be released by December 31, 2020. See related Census 2010 Apportionments.

Apportionment totals were calculated by a congressionally defined formula, in accordance with Title 2 of the U.S. Code, to divide among the states the 435 seats in the U.S. House of Representatives. The apportionment population consists of the resident population of the 50 states, plus the overseas military and federal civilian employees and their dependents living with them who could be allocated to a state. Each member of the House represents, on average, about 710,767 people for Census 2010.

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 Health Care Infrastructure by ZIP Code

.. small area data providing information on sub-county and sub-city/place geographies are challenging to locate and use — particularly in context of demand for healthcare services and demographic attributes of associated neighborhoods. Develop insights into the healthcare infrastructure by ZIP code using the two related resources reviewed here — 1) individual ZIP code demographic-economic profiles and 2) ZIP code demographic-economic interactive tables. One way to examine the healthcare infrastructure for an area is to view/analyze the number and attributes (employment, earnings) of healthcare establishments by types of business/industry (such as physicians office or hospitals). Data and tools reviewed here provide insights into characteristics and patterns of national scope ZIP code areas — examine your ZIP codes of interest.

Option 1 — ZIP Code Profiles
.. examining the healthcare infrastructure in context of the related demographic-economic situation … the following graphic shows ZIP code 10514 (Westchester County, NY) with a bold red boundary.  Census tracts are shown with black boundaries with tract codes as white labels. See more about ZIP-Tract relationships. Cities/places are shown with blue cross-hatch pattern.

– view created with CV XE GIS software and related GIS project.

The above map graphic is part of a ZIP Code 10514 profile (click link to view complete profile). Section 3.1. of the profile shows the number healthcare establishments in the ZIP Code as partly shown in this graphic:

The portion of the table shows the NAICS/type of business code at left, followed by type of business description and the number of establishments at the right.

Examine other characteristics of this ZIP code profile and in context of others via this related Web section. These profiles update in May 2018.

Option 2 — ZIP Code Health Care Sector comparative analysis
.. examining the healthcare infrastructure for a set of ZIP codes in a state, metro, county or peer group … use the interactive table located here to view/rank/compare health care business establishments by type of business for a selected set of ZIP codes. This table shows a query placed on the table to show the total number of offices of physicians for ZIP codes in the vicinity of ZIP 10514. It shows that there are 14 offices of physicians establishments and 13 have 1-4 employees.

About These and Related ZIP Code Data
Data used to develop the tools/resources described above are based in part on the Census Bureau County Business Patterns program. These establishment data update annually.

ZIP code demographic-economic interactive tables
Use the following tables to examine a wide range of ZIP code demographic-economic conditions:
  • General Demographics
  • Social Characteristics
  • Economic Chacteristics
  • Housing CHaracteristics
