The millennials have landed.

The group, often defined as those adults who are 18 to 35 this year, became the largest age group in the workplace in 2015, overtaking both the much smaller Generation X and the baby boomers, according to the Pew Research Center. Millennials now make up more than a third of the U.S. workforce, and as much as 21.5 percent of lawyers in the U.S., according to the current population survey of the U.S. Bureau of Labor Statistics.
