Census 2020 – First Results

.. the first results of Census 2020, the apportionment data, were released on April 26, 2021.  Based on the decennial census, the United States total resident population increased from 308,745,538 (2010) to 331,449,281 (2020), a change of 22,703,743 (7.3%). For now, these data should be trusted and assumed accurate.  The apportionment data provide only total population counts at the state level.  More will be revealed about the accuracy of these data when the redistricting data are released in August 2021.

Apportionment of the U.S. House of Representatives
Congressional apportionment is the process of dividing the 435 members, or seats, in the House of Representatives among the 50 states based on the population data from the decennial census. See more about congressional districts and demographic-economic characteristics. See this related web section for detailed information on apportionment. Use the interactive table to view/analyze the Census 2010 and Census 2020 apportionment data. The following view shows patterns of congressional seats based on the decennial census. Labels show the number of seats based on the 2020 Census. Color patterns show the change in seats, 2010 to 2020.

Census 2020: the Process & Challenges
Counting the total population and selected population attributes in a pandemic is not only challenging but not possible.  During 2020, as the data were collected, it seemed good news that more than two-thirds of the potential respondents had completed the questionnaire.  But then the questions set in.  Bureau public announcements frequently made reference to the number or housing units and the number of households (occupied housing units) “accounted for” reaching 90 percent and progressively more.  By observation, using administrative record data, and other methods, housing units can be much more easily counted than the population and population attributes.  Likewise, determining the number households is  easier than determining the population count and characteristics.

The fact that the state population counts were unexpectedly different from the Bureau’s model based estimates is troubling.  We seek more assurance that the count of  population and population characteristics — by location — are as represented by the apportionment data.

Census Bureau 2020 Model-Based Estimates
New Census Bureau sourced U.S. by county model-based population estimates by age/gender/race-origin as of July 1, 2020 will be released by the Bureau in May 2021.  These estimates are independent of Census 2020 and make use of methods used annually throughout the 2010-2020 period.  An upcoming blog will report on ProximityOne’s analysis of these estimates in comparison with the Census 2020 data.

ProximityOne Estimates & Projections to 2060
ProximityOne annual demographic estimates and projections 2010-2060 by county will begin a new update cycle in May 2021.  The schedule is shown here.  

Starting with the May updates, two base projection series will be developed and progressively updated: one controlled to the Census 2020 data and one based on continued use of 2020 model-based estimates. As more information is released from Census 2020. Follow this blog for more information on evolving developments.

The Value of Demographic Insights

.. its a global thing, a community thing, a business thing, a personal thing … demographics tell us about how, when, where we have changed and how we might change in the future .. and how that change might impact you .. us.

How & Why are County Demographics Changing?

Their application and use creates the value. .

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.

– 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.
