When State Unemployment Falls, Do Cleaning and HVAC Jobs Grow?

Original research · FRED state unemployment ({ST}UR) × BLS QCEW private employment · Primary window 2024→2025 · Panel 2022–2025 · Published September 16, 2026

Service payroll hiring is not lockstep with state unemployment. Across cleaning, landscaping, plumbing/HVAC, and daycare, year-over-year changes in state unemployment rates barely track payroll employment changes (pooled Pearson |r| mostly under 0.10). In 2024→2025 alone, 36 of 51 jurisdictions added plumbing/HVAC jobs while unemployment rose — and cleaning, landscaping, and daycare each show dozens of the same “hired through a softer labor market” cases. This is a correlation check, not a claim that unemployment causes (or blocks) hiring, and not a best-state ranking.

Key findings

  1. Near-zero coupling in the 2022–2025 panel. Pooled correlations of Δ unemployment (pp) vs Δ employment (%): cleaning +0.03, landscaping -0.02, plumbing/HVAC -0.09, daycare -0.08 (n=153 state-years each). None look like tight inverse lockstep.
  2. 2024→2025 is the same story. Cleaning r=+0.07; landscaping r=+0.04; HVAC r=-0.08; daycare r=+0.29 (a mild positive association — not causation).
  3. Many states hired while unemployment rose: cleaning 25/51, landscaping 29/51, plumbing/HVAC 36/51, daycare 29/51.
  4. National payroll still grew in 2024→2025: cleaning +0.3%, landscaping +1.3%, plumbing/HVAC +2.2%, daycare +0.9% (U.S. private QCEW).
  5. Hypothesis held. Soft labor markets and service hiring often coexist at the state level — distinct from pay levels and from within-year landscaping seasonality.

How to read r: −1 would mean unemployment and payroll move as perfect opposites; 0 means no linear link. Values near zero mean state UR changes are a poor predictor of these industries’ hiring.

These are descriptive outliers — states where both unemployment and industry payroll employment rose in 2024→2025 — sorted by employment gain. Small bases can produce large percentages.

Our summer 2026 heat versus earlier plumbing/HVAC employment comparison pairs NOAA cooling-degree days with a pre-summer BLS baseline across 48 states. Its descriptive correlations do not establish causation, hiring flows or technician shortages.

Methods and limitations

Data sources and period matching

Unemployment: FRED monthly series {ST}UR for all 50 states + D.C. (51 series). Calendar-year average of published monthly values. For 2025, most states have 11 published months (one month often missing as .); averages use available months only.

Employment: BLS QCEW annual open CSV slices, private ownership, NAICS 561720 (janitorial), 561730 (landscaping), 23822 (plumbing & HVAC contractors — 5-digit rollup after the 2022 split of former 238220), 624410 (child day care). Years 2022–2025 fetched 2026-09-16.

Matching: Same calendar years for UR and employment — no intentional lag. Primary window 2024→2025; robustness windows 2022→2023 and 2023→2024. Suppressions (N) are never treated as zero; this pull had zero state×industry suppressions for these cells.

Limitations
  • Correlation ≠ causation. Demographics, migration, weather, housing, and industry mix all affect hiring.
  • QCEW is UI-covered payroll only — most nonemployers sit outside this frame.
  • Plumbing/HVAC cannot be split to HVAC-only at state grain in current QCEW.
  • 2025 FRED averages are slightly incomplete vs a full 12-month year; QCEW annual vintages can revise.
  • Not a best-state score, wage study, or seasonal-amplitude study.
Hypothesis

We hypothesized that service hiring is not lockstep with state unemployment. The weak correlations and large “hired while UR rose” counts support that framing.
