Industrial production and capacity utilization data for March 2020 are now available.Total industrial production fell 5.4 percent in March, as the COVID-19 (coronavirus disease 2019) pandemic led many factories to suspend operations late in the month.

The decreases for total industrial production and for manufacturing were their largest since January 1946 and February 1946, respectively. The indexes for utilities and mining declined 3.9 percent and 2.0 percent, respectively. At 103.7 percent of its 2012 average, the level of total industrial production in March was 5.5 percent lower than a year earlier. Capacity utilization for the industrial sector decreased 4.3 percentage points to 72.7 percent in March, a rate that is 7.1 percentage points below its long-run (1972–2019) average.The estimates in this release incorporated data on stay-at-home orders as well as other information on industrial activity for late in the month.
