forecast of the Atlanta Fed.
Rather, it is best viewed as a
running estimate of real GDP
growth based on available
economic data for the current
measured quarter. There are no
subjective adjustments made to

solely on the mathematical results
of the model.

With the absence of government data, the model is reliant on private data like today’s ISM manufacturing index. Impact was a 0.1% uptick.
