From the Chicago Fed: Index points to a moderation in economic growth in March
Led by slower growth in production- and employment-related indicators, the Chicago Fed National Activity Index (CFNAI) declined to +0.10 in March from +0.98 in February. Three of the four broad categories of indicators that make up the index decreased from February, but two of the four categories made positive contributions to the index in March. The index’s three-month moving average, CFNAI-MA3, decreased to +0.27 in March from +0.31 in February.

This suggests economic activity was above the historical trend in February (using the three-month average).
According to the Chicago Fed:
The index is a weighted average of 85 indicators of growth in national economic activity drawn from four broad categories of data: 1) production and income; 2) employment, unemployment, and hours; 3) personal consumption and housing; and 4) sales, orders, and inventories.

A zero value for the monthly index has been associated with the national economy expanding at its historical trend (average) rate of growth; negative values with below-average growth (in standard deviation units); and positive values with above-average growth.
