Why It Matters
Every time you see "Columbus metro unemployment at 3.4%" in a market post or investor report, that number comes from LAUS. It's the BLS program responsible for producing unemployment rates below the national level — for every state, every metro, and every county in the country. LAUS data is monthly, publishes with a ~3-week lag (prior month's data lands around the 20th), and covers labor force, employment, and unemployment for every metro and county. Two things to know: LAUS at metro grain is NOT seasonally adjusted, so comparing month-over-month numbers is misleading; use year-over-year. And the methodology combines Current Population Survey data with an econometric model, not a direct survey of every metro.
At a Glance
- What it is: The BLS program that produces monthly unemployment rates at the state, metro, and county level.
- Why it matters: Every metro-level unemployment number in real estate analysis comes from LAUS. It's the free, federal, canonical source.
- How to use it: Pull YoY unemployment changes (not MoM — metro data is not seasonally adjusted) to assess a market's labor health. Compare to national rate to identify outperforming or underperforming metros.
- Publication lag: ~3 weeks — prior month's data publishes mid-month.
- Seasonal adjustment: National LAUS is SA; metro LAUS is NSA. Cross-check with YoY or rolling averages when comparing sub-state data.
How It Works
What LAUS actually produces. LAUS is the Bureau of Labor Statistics program responsible for calculating unemployment, employment, and labor force counts for every state, metro (CBSA), and county in the United States. It publishes monthly — typically around the 20th of the month for the prior month's data, so April data lands in mid-May. For each geography, LAUS reports three numbers: the size of the labor force (people working or actively looking for work), the number employed, and the number unemployed. The unemployment rate is unemployed ÷ labor force. Methodology overview at Wikipedia's BLS page and the program's home at bls.gov/lau (direct curl blocked by anti-bot). Every metro-level unemployment number cited in real estate analysis — whether from a bank research team, a journal article, or a metro hub page — flows from LAUS.
How the numbers are produced. LAUS is not a direct survey of every metro and county. A direct monthly survey of 3,000+ counties would be impossibly expensive. Instead, BLS combines data from three sources: the Current Population Survey (CPS, a national household survey), state Current Employment Statistics (CES) payroll data, and administrative unemployment insurance claims. These inputs feed into a time-series econometric model that estimates local unemployment at the county and metro grain. The model is tuned so that when you roll up all the states, the total matches the national CPS number. BLS is transparent about the estimation — the underlying methodology is documented publicly, and annual revisions incorporate benchmark data from other programs. But the practical point for investors: LAUS monthly numbers are model estimates, not direct counts, so they revise as new information arrives.
Seasonal adjustment — national vs sub-state. LAUS data at the national level is seasonally adjusted (SA) — the published number strips out predictable seasonal patterns like summer retail hiring or holiday warehouse spikes. Sub-state LAUS data (metro, county, state) is NOT seasonally adjusted by default. Why: the signal-to-noise ratio at the county level is too low for the standard SA methodology to work reliably; the adjustment would introduce more artifacts than it removes. Practical consequence: comparing November to December unemployment at the metro level will pick up holiday retail hiring as "unemployment dropped" even though the underlying labor market didn't change. Use year-over-year comparisons at metro grain, or rolling 12-month averages. FRED publishes both SA and NSA versions of state-level LAUS; for CBSA and county you typically get NSA only.
Where LAUS shows up in real estate analysis. Every serious metro-level labor market analysis uses LAUS. Our own metro hub pages pull LAUS monthly unemployment and job growth comparisons. BEA regional personal income data and LAUS are the two labor-market pillars of metro economic health. Wage growth data comes from a sister BLS program (QCEW or OES), but the unemployment rate is always LAUS. FRED distributes all LAUS series, indexed by FIPS for counties and by CBSA for metros. For underwriting, the two questions LAUS answers: "Is this metro's labor market tighter or looser than the national baseline?" (metro unemployment vs national unemployment), and "Is it trending better or worse?" (YoY change in metro unemployment vs national YoY change).
Real-World Example
Carlos Medina compares LAUS for two metros before buying.
Carlos is choosing between Cleveland and Columbus for his next rental. He pulls LAUS monthly unemployment for both, comparing to the national rate:
- Cleveland MSA (CBSA 17460): Feb 2026 unemployment = 4.6%, up 0.3 points YoY
- Columbus MSA (CBSA 18140): Feb 2026 unemployment = 3.1%, flat YoY
- National: 4.0%, up 0.1 points YoY
Columbus is tighter than national and stable; Cleveland is looser than national and softening. Both are within normal ranges, but the trend divergence matters. He checks the prior 3 months of LAUS for each — Cleveland has been drifting up month-over-month for 6 months straight; Columbus has held between 3.0-3.2% throughout.
He knows the metro-level numbers are not seasonally adjusted, so he doesn't read the month-to-month wiggles as signal. But the 6-month drift in Cleveland is real enough to flag. He narrows his search to Columbus.
Without LAUS, he'd be relying on news headlines or commercial research that sourced the numbers from LAUS anyway. Pulling directly from BLS (or via FRED) gives him the data without an intermediary's spin.
Pros & Cons
- Free, federal, monthly — the canonical source for sub-national unemployment data
- Covers every state, every metro (CBSA), every county — one dataset for any geography
- Documented methodology and public revisions make it auditable
- Distributed through FRED and other federal portals, so automation is straightforward
- 60+ years of historical data for structural analysis
- Metro-level data is not seasonally adjusted — requires YoY comparison, not MoM
- ~3 week publication lag means monthly data is backward-looking for real-time decisions
- Small metros have thin CPS samples, so the model's estimates can be noisy
- Annual benchmark revisions can shift prior months' reported numbers by 0.2-0.5 points
- Unemployment rate alone doesn't capture labor force participation — a metro can have "low unemployment" because people have stopped looking for work
Watch Out
- Don't compare metro LAUS month-to-month without adjusting: Metro data is NSA. December vs November will pick up holiday retail hiring as apparent unemployment change. Use YoY.
- Watch for benchmark revisions: Every January, BLS revises the prior year's LAUS data against annual benchmarks. A metro that looked "stable at 3.5%" can get revised to "drifted from 3.3% to 3.7%." Pull current data before publishing analysis.
- Labor force participation matters: A metro's unemployment rate can drop because people gave up looking — not because hiring accelerated. Always check participation rate alongside unemployment rate for a complete read.
- Small metros have wider confidence intervals: LAUS methodology is model-based and CPS samples in small metros are sparse. A 3.5% unemployment rate in a 50,000-person metro has much larger uncertainty than in a 2-million-person metro.
- LAUS ≠ CES: LAUS measures unemployment (household-based). Current Employment Statistics measures payroll job counts (establishment-based). They can diverge — a metro can show job growth in CES while LAUS unemployment drifts up, or vice versa. Check both for a complete labor market picture.

The Takeaway
LAUS is the federal answer to "what's the unemployment rate in my metro." It's free, monthly, covers every metro and county in the U.S., and is the source every serious real estate underwriter uses. Two rules: use YoY comparisons for metro data (NSA), and always pair unemployment with labor force participation. BLS publishes the raw data; FRED makes it easy to pull; every commercial platform reporting "metro unemployment" ultimately cites LAUS.
