National Bureau of Economic Research (NBER)

What Is National Bureau of Economic Research (NBER)?

The National Bureau of Economic Research (NBER) is a private, nonprofit research organization that is the official, widely recognized arbiter of U.S. recession start and end dates. Rather than applying a mechanical rule such as two consecutive quarters of GDP decline, the NBER's business cycle dating committee weighs a broad set of monthly indicators, including employment (nonfarm payrolls), real income, and spending, to judge whether a significant, economy-wide downturn has occurred. Its determinations are made carefully and often well after a turning point, so recession dates are typically announced months after they begin or end. This deliberate, multi-indicator approach means the NBER can decline to call a recession even when GDP has fallen for two quarters, as it did for the first half of 2022.

Why It Matters

The NBER matters because its rulings are the reference point economists, journalists, and governments use when they say the U.S. is in a recession. Because it relies on multiple indicators rather than GDP alone, its judgments can differ from the popular two-quarter rule of thumb, which is why official and informal recession talk sometimes conflict. The trade-off is timing: by waiting for enough data to confirm the depth, breadth, and duration of a downturn, the NBER provides authoritative dates but only in hindsight, not in real time. That lag is why analysts also watch faster leading indicators for early warning signs. Understanding the NBER's role clarifies that a recession is an official, backward-looking determination about the whole economy, not a label triggered automatically by any single statistic.
