County Demographic-Economic Characteristics & Patterns
  .. resources to create and apply insights

April 2023 .. for many counties the pandemic has impacted each component of population change: births, deaths and migration. The magnitude and duration of the impact on each component varies by county and become more measurable in the months ahead.

Counties, and county equivalent areas such as independent cities, are the primary political subdivision of states. The relative stable geography of counties, with good national scope geographic granularity, makes these areas appealing for use in tabulating data and analyzing demographic-economic data. This section provides information on tools and data related to accessing, integrating analyzing county demographic-economic patterns and trends. .. updates ,, interactive table

Patterns of Percent Net Migration by County: 2021-2022
The following graphic shows patterns of percent net migration by county for the two-year period 7/1/20 to 6/30/22. See details below about how these data were computed. The largest ten metros (MSAs) are highlighted with bold black boundaries.

- the above view, and interactive variants, may be viewed using the CountyTrends GIS project with the VDA Web GIS.

Population & Components of Change
Total population for an area can be computed as a sum of components of change:
Population (7/1/22) = Population (7/1/21)
  + Births (6/30/21 to 7/1/22)
  - Deaths (6/30/21 to 7/1/22)
  + Net International Migration (6/30/21 to 7/1/22)
  + Net Domestic Migration (6/30/21 to 7/1/22)

How & Why County Demographics are Changing: 2020-2022 .. goto top
The following graphic shows how a county is changing (layers for gaining or losing population) and why a county is changing (interval for mainly net migration and interval for mainly natural chnage). The largest ten metros (MSAs) are highlighted with bold black boundaries.

- click graphic for larger view and details.
- the above view, and interactive variants, may be viewed using the CountyTrends GIS project with the VDA Web GIS.

For example, the computation to determine "gaining, mainly natural change" (green) is:
(popest22-popest20)>0 and (netmig20+netmig21+netmig22)<=(natchg20+natchg21+natchg22)
.. the determination for Harris County, TX is:
(4780913-4734505)>0 and (-5261 + -26615 + 17262 )<=( 7446 + 26061 + 30117) or
(46408)>0 and ((-14614)< (63624))

Computing Patterns of %Net Migration by County: 2021-2022 .. goto top
The %net migration graphic above show patterns of %net migration by county for the two-year period 7/1/20 to 6/30/22. Intervals shonw in the legend panel are based on these end points (average of two years:
(100*(NETMIG21/popest21)+100*(NETMIG22/popest22))/2 >=3 -- top interval where
NETMIG21 .. net migration during the period 6/30/20 to 7/1/21
popest21 .. population as of 7/1/21
NETMIG22 .. net migration during the period 6/30/21 to 7/1/22
