Impact of Climate Change on Demographics
.. Annual population estimates 2010 to 2060 reflecting climate change
.. population estimates & projections for U.S., states, metros, counties, tracts
.. incorporating results of Census 2020 and the pandemic

September 2022 .. how are county demographics changing in face of the pandemic, climate change and related factors? Factors affecting subcounty areas with different rates of onset and size are reflected in our October 2022
The projections reflect the disproportionate ways and levels that climate change will impact the population:
.. Fertility, mortality and migration impacted due to climate change factors.
.. Flooding from sea level rise, increased storm intensities
.. Water shortages from droughts
.. Wildfires and drier conditions
.. Warmer temperatures allowing disease to spread
.. Reduced air quality from warmer temperatures
.. Increased in energy consumption (air conditioning and otherwise)
.. Health related employment and productivity losses

Population Percent Change by County 2010-2060

Demographic Projections by ProximityOne
Demographic projections to 2060 are a part of the ProximityOne Situation & Outlook (S&O). These data are used by private and public sector organizations to meet management, research, planning and analytical needs. See how USA TODAY used these data to analyze county level diversity 2060 .. view a county/state diversity profile for any county.

U.S. County Population Trends: 2010 - 2060 Interactive Table .. gototop
This table contains illustrative data. See terms of use below.
    .. we develop annual updates with revisions during the year.

Usage Notes
General navigation:
  • Use vertical scroll bar at right to scroll across areas.
  • Use horizontal scroll bar below table to scroll right & view 2010-2060 change.
  • Click a column header to sort on that column; click column header again to sort in other direction.
  • Click ShowAll button to show all areas.

Filtering & queries:
  • Click ShowAll button between queries.
  • Click State (dropdown below table) to select all areas in a selected state.
  • Key in text/area name in text box to right of Find-in-Name button then click button to locate all matches (case sensitive).
    .. searches column 1; default is Harris (for Harris County-Houston TX area); use your own area name of interest.
  • Key in CBSA/metro code in text box to right of Find-in-CBSA button then click button to locate all matches (case sensitive).
    .. optionally get 5-character CBSA code from scroll section (above, right).
    .. searches CBSA column, default is 26420 (Houston TX metro); use a CBSA code of interest.

Column Headers
  • Type - Type of geography; summary level (see below)

  • Ch2010-60 -- population change 2010 to 2060
  • %Ch2010-60 -- percent population change 2010 to 2060

Methodology & Vintages go to top
Demographic projections presented in this section are developed using an annual time series model. The population in period t (P[t]) for a county is defined/projected using the identity:
  P[t]:=P[t-1]+B[t]-D[t]+IM[t]+DM[t], where:
- P[t] -- resident population as of 7/1/t
- P[t-1] -- resident population as of 7/1/t
- B[t] -- births during the period 6/30/t-1 to 7/1/t
- D[t] -- deaths during the period 6/30/t-1 to 7/1/t
- IM[t] -- international migration during the period 6/30/t-1 to 7/1/t
- DM[t] -- domestic during the period 6/30/t-1 to 7/1/t

  • Projections are developed as vintages (released on a certain date).
  • County projections are developed annually and are updated in March and July
    .. the July update integrates updated age, race/origin and gender detail
    .. data presented in the table are extracts showing total population every 10 years
    .. the underlying dataset includes annual data for many items used in the model
  • Projections are developed for various scenarios.
    .. the option 2 scenario uses these assumptions:
    .. crude birth rate declines over time
    .. crude death rate increases over time
    .. migration follows patterns exhibited during the period 2010-2020
    .. historical annual data for the period 2010 through 2020 use Census Bureau estimates
    .. some counties are adjusted for specific circumstances
  • Different model specifications and vintages will have different projected values.

Demographics2060 Software & Data Analytics go to top
The Demographics2060 software is used to develop, manage access to and support analysis of the demographics estimates and projections. A version of the Demographics2060 Windows based software is available to users of the Demographics2060 data. The start-up view of the application is shown below. The grid, showing a profile for Fresno County, CA, can be structured to show different data views, such as comparative analysis, percentages, selected items across geography by row, etc. Optionally revise individual county models used to develop the projections. Link data from other sources. See sample profiles below created by 1) dbl-clicking a geoname from listbox at left, then 2) clicking SaveXLS button.

Profile Organization & Usage go to top
The following county base profile examples (links opening XLS spreadsheets) illustrate how the profiles are organized. These data are multi-sourced from ProximityOne and Federal Statistical System agencies. These examples makes use of the "base" profile with data running by year across columns, 2010-21, and subject matter by row. The base profiles update frequently. See the above projections schedule for additional information. Members of the no fee ProximityOne User Group receive email updates. Join here. Projections are not provided here; the projections continue to the 2060 column where provided.

The profiles are organized into four sections:
  • General Demographics (all counties; only these items are projected 2060)
      .. population and components of change
      .. selected population groups
      .. population by gender
      .. population by race/origin
      .. population by single year of age
      .. population by 5-year age and other age groups
  • Social Characteristics (counties 65,000 population or more; projections to 2030)
      .. households and living arrangements
      .. educational attainment
  • Economic Characteristics (projections to 2030)
      .. households by income (counties 65,000 population or more)
      .. median household income
      .. establishments by sector
      .. employment by sector
      .. wages by sector
      .. real GDP by sector
  • Housing Characteristics (projections to 2030)
      .. housing units by occupancy & tenure (counties 65,000 population or more)
      .. new residential construction (number of units & values) by units in structure
      .. housing price index (counties where available; based on transactions activity
