Mapped: A Decade of Population Growth and Decline in U.S. Counties




If an area sees a high number of migrants, along with a strong birth rate and low death rate, then its population is bound to increase over time. On the flip side, if more people are leaving the area than coming in, and the region’s birth rate is low, then its population will likely decline.

Which areas in the United States are seeing the most growth, and which places are seeing their populations dwindle?

This map, using data from the U.S. Census Bureau, shows a decade of population movement across U.S. counties, painting a detailed picture of U.S. population growth between 2010 and 2020.

The Myth of the Disease-Ridden Red States




Another way of looking at this is to look at the Year over Year change of rates within each group. As you can see from the chart below, the percentage change remains pretty consistent among each individual grouping, with 2020 seeing the largest change rate, and 2021 seeing a small but significant change rate from 2020 (meaning overall mortality was still quite elevated relative to 2019).

In summary, when we take a historical view and higher level view while maintaining these same groupings, these stark differences in Covid-19 mortality rates do not seem to translate into overall morality rates. Why?

At the risk of this analysis turning into another pile-on pointing out the New York Time’s errors, I’d like to offer a more benign explanation. It’s one that has plagued journalists and reports throughout the pandemic. Why is it that everything is framed in Red and Blue? One simple reason: the availability of the data. Leonhardt is using data that is easily accessible and is already formatted for easy analysis.

This is what is called an availability bias. It’s essentially creating a hypothesis or completing a study based on a specific set of data, purely for no other reason than that the data is there. Just because the data is available does not mean it’s the best data to use to try to answer a question.

More than Half of U.S. Counties Were Smaller in 2020 Than in 2010




Almost half (47%) of U.S. counties or equivalents gained population between 2010 and 2020 (Figure 1).

Five counties (metro areas in parentheses) gained at least 300,000 people during that period: Harris County, Texas (Houston-The Woodlands-Sugar Land); Maricopa County, Arizona (Phoenix-Mesa-Chandler); King County, Washington (Seattle-Tacoma-Bellevue); Clark County, Nevada (Las Vegas-Henderson-Paradise); and Tarrant County, Texas (Dallas-Fort Worth-Arlington).

California’s Los Angeles County remained the largest county in 2020, crossing the 10.0 million-person mark between 2010 and 2020.
