Beacon CRE

How the growth numbers are computed

Every number on Beacon CRE's growth pages is a published U.S. federal statistic (Census Bureau, Bureau of Labor Statistics or IRS), shown with its own period and source; changes compare the latest period with 5 years earlier, and ranks compare only areas with a figure for the same period.

Figures last refreshed

Summary sentences on each page are written by fixed rules from these numbers, not by AI. Figures are informational only, not investment advice.

Headline measures

9 measures appear on the county, metro and rankings pages. Each tile on a page shows its own period: one page can mix years, because each agency publishes on its own schedule.

Population

Resident population, July 1 estimate

Source
U.S. Census Bureau, Population Estimates Program (Vintage 2025)
Period
Latest: 2025 (3,144 counties). Change compared with 2020. Series from 2020.
How it is computed
The Census Bureau's resident population estimate for July 1 of each year (so "since 2020" means July 1, 2020, not the April 1 census day). Change is the percent change from 5 years before the latest period, or from the earliest period loaded when that year is missing.

Annual

Net domestic migration

People moving in from other U.S. counties minus people moving out

Source
U.S. Census Bureau, Population Estimates Program (Vintage 2025)
Period
Latest: 2025 (3,144 counties). Series from 2021.
How it is computed
Net domestic migration for the year to June 30: people who moved in from other U.S. counties minus people who moved out. Moves to and from other countries are counted separately, as international migration. Per 1,000 residents divides by the same year's population estimate; counties with fewer than 1,000 residents get no per-resident rate. The multi-year total adds every year loaded, and the components table adds natural change and the Census adjustment.

Annual

Jobs

Average annual employment covered by unemployment insurance

Source
U.S. Bureau of Labor Statistics, Quarterly Census of Employment and Wages
Period
Latest: 2025 (146 counties). Change compared with 2020. Series from 2020.
How it is computed
The annual average of monthly employment covered by unemployment insurance, all industries and ownerships (private and government). Change is the percent change from 5 years before the latest period, or from the earliest period loaded when that year is missing. QCEW: NC/SC only. Outside North and South Carolina, jobs are private-sector employment from County Business Patterns.

Quarterly

Average weekly wage

Average weekly wage, all covered jobs

Source
U.S. Bureau of Labor Statistics, Quarterly Census of Employment and Wages
Period
Latest: 2025 (146 counties). Change compared with 2020. Series from 2020.
How it is computed
Total covered wages divided by covered jobs, per week, all industries and ownerships, in dollars of each year (not adjusted for inflation). Change is the percent change from 5 years before the latest period, or from the earliest period loaded when that year is missing. QCEW: NC/SC only: pages outside North and South Carolina show no wage figure.

Quarterly

Unemployment rate

Annual average unemployment rate

Source
U.S. Bureau of Labor Statistics, Local Area Unemployment Statistics
Period
Latest: 2025 (3,143 counties). Change compared with 2019. Series from 2010.
How it is computed
The annual average unemployment rate (BLS series period M13). Change is in percentage points, measured from 2019 (the last year before the pandemic spike) when that year is loaded, otherwise from 5 years earlier.

Monthly

New homes permitted

Housing units authorized by building permits in the year

Source
U.S. Census Bureau, Building Permits Survey
Period
Latest: 2025 (3,024 counties). Change compared with 2021. Series from 2021.
How it is computed
Housing units authorized by building permits in the calendar year, from the Census Bureau's annual county files: units in 1-unit, 2-unit, 3-4-unit and 5+-unit buildings, including the Bureau's estimates for places that did not report. Permits count homes authorized, not homes finished. Per 1,000 residents divides by the same year's population estimate; counties with fewer than 1,000 residents get no per-resident rate. Change is the percent change from 5 years before the latest period, or from the earliest period loaded when that year is missing.

Annual

Median household income

American Community Survey 5-year estimate

Source
U.S. Census Bureau, American Community Survey 5-year estimates
Period
Latest: 2020–24 (3,144 counties). Change compared with 2016–20. Series from 2016–20.
How it is computed
The median household income from the American Community Survey 5-year estimates, in dollars of the survey's last year. The change compares the latest 5-year window with the earliest window loaded; the two windows can share a year and are not adjusted for inflation, so read the change as a rough guide.

Annual

Private-sector employment

Paid employees of private employers in mid-March (County Business Patterns)

Source
U.S. Census Bureau, County Business Patterns
Period
Latest: 2023 (3,142 counties). Change compared with 2018. Series from 2018.
How it is computed
Paid employees of private employers in the pay period including March 12 (County Business Patterns). Government jobs and the self-employed are not counted. Change is the percent change from 5 years before the latest period, or from the earliest period loaded when that year is missing.
Agency releases
Annual

Net migration (IRS tax returns)

People on tax returns moving in minus moving out, U.S. and abroad; the sum of the member counties (moves between them cancel out)

Source
IRS Statistics of Income, U.S. Population Migration Data
Period
Latest: 2022–23 (896 areas).
How it is computed
People on tax returns (exemptions) who moved in minus those who moved out between one filing year and the next, U.S. and abroad; people who do not file are not counted. Metro pages add up the member counties, so moves between them cancel out.
Agency releases
Annual

Population components (births minus deaths, international migration and the Census adjustment) come from the same Census population estimates, from 2021 on (the 2020 figures cover April to July only).

Changes and small numbers

How ranks are built

Each county is ranked within its state and against every U.S. county with a comparable figure. "County" includes county equivalents: independent cities, parishes, and Alaska boroughs and census areas.

Who is left out of a rank:

On North and South Carolina county pages, the opening sentence ranks population and job growth among the 146 counties of both Carolinas; the rank table ranks within the state and the U.S. Metro and micro areas are ranked separately from each other.

Which pages are indexed

How often data refreshes

Beacon CRE's data pipeline checks the federal sources every day. A new release reaches this site after it passes our checks, and every page shows the date its figures were last refreshed. The figures on this site were last refreshed on . The agencies publish on these cycles:

Licensing

Every figure on the growth pages is a work of the U.S. Government and in the public domain (17 U.S.C. 105). You may reuse it; please cite the agency. Beacon CRE's page text and layout are not public domain.

Using federal data does not mean any agency endorses Beacon CRE. More on every layer: data sources and licences.

What is not included

The $99 county report

The report for a county outside North and South Carolina is built from the same federal sources as these pages, with a source next to every number. It adds these figures, which are not on the free pages:

The last-12-months permit count comes from the Census Bureau's monthly county files, which are preliminary and cover only places that report monthly. The report's own methods page says:

North and South Carolina county reports add Carolinas layers; each report lists its own sources.

Outlook in the Carolinas quarterly report

The free growth pages show only published past values. The paid quarterly report for a North or South Carolina county adds a 5-year and 10-year outlook for some measures (population, jobs (county business patterns), homes permitted per year, median gross rent), each with an 80% range, counted from the latest year of data.

  • Each method is backtested: it forecasts past years from the data available at the time, and its errors are compared with simple baselines ('same as the latest year' and straight-line trends).
  • A model is used only if it beat the best baseline in those tests, by a statistical test at the 10% level, with at least 3 past years tested.
  • The report prints a cell only when such a model exists for that county, measure and horizon, with its tested average error and the number of past years it was tested on. Trend-only, untested and 'no reliable forecast' cells are left out, and a measure with no tested cell is not shown.
  • The 80% ranges come from the backtest errors. At 5 years and beyond, outcomes fell inside the range less often than 80% of the time for several measures, so read the range as a guide, not a guarantee.
  • An outlook is an estimate, not investment advice.
