Notes:

Shaded areas indicate decelerations (slowdowns in growth) in the economy, and areas between indicate accelerations (growth) in the economy.

Detrending and smoothing refer to statistical procedures that make it easier to observe changes in upturns and downturns of the data. Detrending removes the long-term growth trend and smoothing removes month-to-month volatility.
