County Population & Components of Change Trends

.. new/updated annual county population estimates … 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 as well as analyzing data. This section provides information on tools and data related to accessing, integrating analyzing county demographic-economic patterns and trends focused on the latest official county population and components of change estimates (through 2014, released March 2015). See related Web page for more details.

Population Components of Change
Annual population and components of change estimates for each county, 2010 though 2014, are included in the dataset used in the create the map shown above. Similar thematic pattern maps can be generated for any county/region for any of these items, or computed items such as birth rate.

Population components of change are shown in the population identity:
P[i,t] = P[i,t-1] + B[i,t] – D[i,t] + MD[i,t] +MI[i,t]
for the ith geographic area; t: year
where the components of population change are:
  – B[i,t] … births in area i in year t
  – D[i,t] … deaths in area i in year t
  – MD[i,t] … domestic migration in area i in year t
  – MI[i,t] … international migration in area i in year t

County Population & Components of Change Interactive Table
Use the interactive table in the related Web section to interactively view, rank, compare annual population and population components of change for all states and 3,143 counties. For counties that are part of a metropolitan area, the table includes the new and previous metro (CBSA) codes.

The following graphic illustrates use of the interactive table. A query is used to view only those counties in the Charlotte metro.
