"What I'm pretty proud to say is 30 percent of my direct reports are women. I've been trying to get the press to write a story about this for years," the bank's chairman and chief executive officer said on CNBC's " Squawk Alley " in an exclusive live interview from Chicago.
"Thirty percent of our top 200 people are women. And they have unbelievable jobs," Dimon said, listing departments such as investment banking, mergers and acquisitions, equity capital markets, private banking and credit cards.
In the latest uproar over the treatment of women in Silicon Valley, Google this week fired a male engineer after he wrote an internal memo that attributed gender inequality in the tech industry to biological causes.
In the interview, Dimon also highlighted his firm's commitment to racial equality.
He pointed out the company has "a black woman who runs our retail division who's on our trip with us." Thasunda Duckett was named CEO of consumer banking in September after heading the firm's auto finance business.
JPMorgan announced Tuesday a $500,000 investment in a Chicago robotics technician training program operated by BSD Industries.
JPMorgan is also "making a special effort" to bring on more African-Americans by setting up a separate group to focus on school recruiting, retention and hiring "more senior African-American talent," Dimon said. "It's starting to work. The numbers are getting better and it's different."
"We have to acknowledge the reason it's different is it's a different history, a different background. A lot of African-Americans didn't grow up in the same neighborhoods as white people," he said.
"We're doing great with women, we're doing great with Asians, we're doing great with Hispanics," Dimon said. "We've got to do better with African-Americans and we're going to."
