U-3 vs U-6 Unemployment Rate
The headline U-3 rate counts only the jobless who are actively looking. U-6 also counts underemployed and marginally attached workers — a broader gauge of labor-market slack.

- U-6
U-3 counts people who are jobless, available for work, and have actively looked in the past four weeks. U-6 adds two groups: people working part-time because they cannot find full-time work ("part-time for economic reasons") and people marginally attached to the labor force — they want a job and have looked in the past year but not in the past month.
U-6 typically runs 3–5 percentage points above U-3. The gap widens during and after recessions, when involuntary part-time work spikes, and narrows in hot labor markets when those workers convert to full-time employment. In the 2010s recovery the gap stayed wide until 2018; in the 2021–22 recovery it closed unusually fast, reflecting labor-market tightness that pulled part-timers into full-time jobs within months.
The BLS also publishes U-1 through U-2 and U-4 through U-5 at intermediate thresholds. The bracket that ranges from U-3 (headline) to U-6 (broadest) captures the distinction most worth tracking for policy and investment decisions.

CPI vs PCE
CPI and PCE are the two main U.S. inflation gauges. They usually move together but measure different baskets with different weights — and the gap between them drives where the Fed sets policy.
Core CPI vs Core PCE
Core measures strip out food and energy — the two most volatile CPI and PCE components — to reveal the underlying inflation trend. Core PCE is the Fed's single most-watched inflation gauge.
CPI vs PPI
The Producer Price Index (PPI) measures prices received by domestic producers. Changes in PPI often show up in CPI several months later — making PPI a leading indicator of consumer inflation.
10-Year vs 2-Year Treasury Yield
When 2-year yields exceed 10-year yields the curve is inverted — and inversions have preceded every U.S. recession since 1955. Compare the two benchmark yields directly.
Fed Funds Rate vs 10-Year Treasury Yield
The federal funds rate is the Fed's lever on short-term interest rates; the 10-year Treasury yield is set by the bond market. Comparing them shows the market's read on Fed policy.

The 30-year fixed mortgage rate closely tracks the 10-year Treasury yield plus a spread that reflects credit risk, prepayment risk, and mortgage-backed-security pricing.
