Even as women have begun speaking out about sexual harassment at work, the number of official complaints to state and federal regulators hit a two-decade low in 2017.

The federal Equal Employment Opportunity Commission and its state-level counterparts received just over 9,600 complaints in 2017, according to data obtained by Bloomberg, down from more than 16,000 in 1997—a 41 percent drop.
