Economic indicators are quantitative data series classified by their timing relative to the business cycle into three categories: leading (change direction before the economy turns), coincident (move with the economy in real time), and lagging (confirm trends after the fact). This three-tier classification system was developed by the NBER in the 1930s and is maintained by the Conference Board, which publishes composite indexes for each category designed to signal peaks and troughs in economic activity.

├── What's the goal?
│ ├── Classify indicators (leading/lagging/coincident)
│ │ └── Economic Indicators ← YOU ARE HERE
│ ├── Predict recession probability

│ ├── Interpret yield curve shape
│ │ └── Yield Curve Analysis
│ ├── Rate impact on businesses
│ │ └── Interest Rate Impact
│ └── Inflation dynamics
│ └── Inflation Framework
├── Which country/region?
│ ├── US → Conference Board LEI, ISM PMI, BLS data
│ ├── Eurozone → PMI (S&P Global), HICP, ECB data
│ └── China → Official NBS PMI + Caixin PMI
└── Timeliness?
├── Real-time (weekly) → Initial jobless claims
├── Monthly → ISM PMI, LEI, nonfarm payrolls
└── Quarterly → GDP (~30 days post-quarter)
Selecting only the ISM PMI because it confirms a bearish view while ignoring strong payrolls and rising consumer spending produces misleading analysis. [src4]
Combine leading (PMI, jobless claims) with coincident (payrolls, industrial production) to build a directionally consistent picture. [src1]
Initial GDP and payroll estimates are frequently revised — advance GDP has been revised by more than 1 percentage point in some quarters. Planning based solely on initial releases can be misleading. [src2]
Compare initial releases to subsequent revisions. The direction of revisions (consistently upward or downward) is itself an informative signal about economic momentum. [src2]
PMI above 50 means more firms are expanding than contracting, but the economy-wide GDP breakeven corresponds to PMI around 42.5, not 50. A PMI of 48 signals slowing, not contraction. [src3]
The ISM notes that readings above 42.5 are consistent with positive GDP growth. A declining PMI even above 50 signals deceleration. [src1]
Misconception: Leading indicators predict recessions with reliable timing.
Reality: Leading indicators predict direction of change, not timing. The LEI declined 15 of 18 months through early 2024 without a recession. [src1]
Misconception: The unemployment rate is a leading indicator.
Reality: The unemployment rate is a lagging indicator — it peaks after recessions end. Initial jobless claims (a LEI component) are the leading labor market indicator. [src2]
Misconception: All PMI surveys measure the same thing.
Reality: ISM Manufacturing PMI covers only manufacturing (~11% of US GDP). ISM Services PMI covers the larger services sector. China has both an official NBS PMI and a private Caixin PMI that often conflict. [src3]
| Concept | Key Difference | When to Use |
|---|---|---|
| Economic Indicators | Broad classification framework (leading/coincident/lagging) | Understanding which data series to monitor for any economic question |
| Recession Indicators | Focused on recession prediction (Sahm Rule, LEI, yield curve) | Specifically assessing recession probability |
| Yield Curve Analysis | Single indicator (term structure) with deep analytical framework | Interpreting bond market signals specifically |
| Inflation Framework | Price-level indicators and monetary policy transmission | Analyzing inflation dynamics and Fed policy implications |
