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.

Examining County Migration: 2010-2016

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.

State Demographic-Economic Briefing Notes

Here we look at the “tip of the iceberg” — intentionally. This section provides links to access State Demographic-Economic Briefing Notes. A summary of selected key demographic-economic measures and trends for each state are presented in comparison with the U.S. Use the Briefing Notes to facilitate briefings to others, collaboration and to obtain a snapshot of current and trending conditions. These data are mostly taken from the more detailed tables available as links at the bottom of each Briefing Notes section.

The Briefing Notes have been developed using the Regional Demographic-Economic Modeling System (RDEMS). The Briefing Notes sections and related detailed tables update frequently.

Knowing “where we are” and “how things have changed” are key factors in knowing about the where, when and how of future change — and how that change might impact you. There are many sources of this knowledge. Often the required data do not knit together in an ideal manner. Key data are available for different types of geography, become available at different points in time and are often not the perfect subject matter. These sections provide access to relevant data and a means to consume the data more effectively than might otherwise be possible. Use these data, tools and resources in combination with other data to perform wide-ranging data analytics. See examples.

Importance of these Data; Projecting Future Patterns
These data are important. They tell stakeholders how the population is changing, when, and where by state, multi-state regions and for the U.S.; overall. Annual measures of population change provide insights into recent patterns and how the population might change during the next few years. These data do not, in general, tell us why the population is changing. More detailed estimates of state and sub-state 2014 population by age, gender and race origin will be released between now and mid-2015.

These historical data, based on facts or near-facts, are used in models to develop projections of how the population size, characteristics and distribution might evolve in the years ahead. The projections need to be updated annually to reflect the more factually based estimates. The models endeavor to capture/specify the why of population change and how change manifests itself by age, gender and race/origin — and the all important where and when.
