Census 2020 P.L. 94-171 Redistricting Data Updates

.. we are just two years away from the first census block level data from Census 2020.  The initial block level data will be the P.L. 94-171 redistricting data.  But before that, the initial Census 2020 TIGER/Line shapefiles/GIS files, the geography, will become available in November 2020, maybe earlier.  Stakeholders will be able to see how block and tract codes and geography have changed in many areas since 2010.  The prototype P.L. 94-171 data (see final file layout and subject matter items) are expected in the last week of March 2019 and will cover the Providence County, RI area. This post shows illustrative views and related details about the area. The Census 2020 P.L. 94-171 program and plans are reviewed in this Federal Register notice.

The applications/views shown below have been developed using the ProximityOne CV XE GIS software and related GIS project.

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.

This section updates January 2020, with corresponding 2019 updates and additional details. Follow (click follow button at upper right) to receive updates on this and geographic, demographic and economic change with drill-down to the street intersection level.

In January 2019, the U.S. is expected to experience one birth every 8 seconds and one death every 11 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 19 seconds … one net international migrant every 34 seconds.

The world population on January 1, 2019 is estimated to be 7,541,221,651. The world has experienced a population increase of 96,777,770, or 1.3 percent, from New Year’s Day 2018 (population 7,444,443,881). During January 2019, 4.8 births and 1.9 deaths are expected worldwide every second.

Assessing Why and How the Regional Economy is Changing

.. data, tools and insights .. which counties are experiencing the fastest economic growth? by what economic component? what does this look like on a per capita level? how might county economic change impact you? Use our county level annual estimates and projections to 2030 to get answers to these and related questions. Get started with the interactive table that contains a selection of these data for all counties and states.

Visual Analysis of Per Capita Personal Income Patterns
The following map shows changing patterns of economic prosperity, U.S. by county, based on percent change in per capita personal income, 2010 to 2017. Create variations of this view — this view uses a layer in the “US1.GIS” GIS project installed by default with all versions of the CV XE GIS software.

Measuring the economy and change. One important part of this is Personal Income and components of change. Personal income is the income available to persons for consumption expenditures, taxes, interest payments, transfer payments to governments and the rest of the world, or for saving. Use the interactive table to examine characteristics of counties and regions of interest; how they rank and compare. The table provides access to 31 personal income related summary measures — the interactive table shows data for one of eight related subject matter groups. See more about the scope of subject matter descriptions.

Assessing How the Economy is Changing and How it Compares
The U.S. Per Capita Personal income (PCPI) increased from $40,545 in 2010 to $51,640 in 2017 — a change of $11,095 (27.4%). Compare the U.S. PCPI (or for any area) to a state or county of interest using the table. For example, Harris County, TX (Houston) .. click the Find GeoID button below the table .. increased from $45,783 in 2010 to $53,188 in 2017 — a change of $7,405 (16.2%).

How the New York Metro is Changing

.. or more precisely, how the New York Metropolitan Statistical Area (MSA) is changing. As of Census 2010 the New York MSA (officially the New York-Newark-Jersey City, NY-NJ-PA MSA) consisted of 20 counties. With the new OMB metropolitan statistical areas defined as of February 2013, the New York MSA became 22 counties, absorbing the Poughkeepsie, NY MSA two counties (Dutchess and Orange). The Poughkeepie MSA was removed from the official MSAs. The delineation remained that way until the new September 2018 delineations when the Census 2010 delineation was restored. Now, the Poughkeepsie, NY MSA exists as a 2 county area and the New York MSA exists as a 20 county area (both as they existed geographically in Census 2010).

These metro-county relationships are shown in the graphic presented below. The Poughkeepsie, NY MSA is shown with the blue cross-hatch to the north and the New York MSA is shown with the salmon color pattern.

– view developed using the CV XE GIS software and related GIS project.
– see the related New York Metro Situation & Outlook report.

What Difference Does it Make?
A lot! First, during the interim period 2013-2018, the Poughkeepsie, NY MSA lost the metropolitan area identity/status as conferred by the OMB delineations. It might have been omitted from size class market development and research analyses. Related, that metro was not included as a tabulation or estimation area of MSAs by Federal statistical agencies. An example of the impact is that the official demographic estimates for the Poughkeepsie, NY MSA developed by the Census Bureau were not tabulated as such and omitted from various statistical reports. Also, the removal of designation and now adding the designation back, creates a hiccup in the time series — affecting both the Poughkeepsie NY MSA and the New York MSA.

Looking Forward
The September 2018 CBSA delineations define counties that will be used for Census 2020 (likely, there could be yet further changes) — 384 MSAs in the U.S. In the cases of the New York MSA and the Poughkeepsie, NY MSA, it appears that the geography (component counties) used for Census 2010 will be the same as for Census 2020. Going forward, ProximityOne estimates and projections will use the most current vintage of CBSAs.

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
The following graphic shows patterns net domestic migration for the period 2011-2017, based on the model-based estimates. The patterns of migration change, direction and magnitude are immediately evident. Click on the graphic to see a larger view showing more detail. Expand browser to full screen for best quality view. The larger view shows a portion of a mini-profile for Florida. The mini-profile illustrates how these data are comprised … annual net domestic migration estimates and the sum over the years 2011-2017. See the interactive table to view these data, and related components of change, in a tabular, numeric form.

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.
