Headcount increased at the nation’s largest law firms last year, but a lot of the growth came from U.S. firms adding foreign lawyers through international mergers, according to the National Law Journal’s annual NLJ 350 survey.

Headcount at the 350 firms rose 3.9 percent last year, after growth of just 1.1. percent in 2012. The NLJ, a Daily Report affiliate, has summarized its findings for those who prefer animated Godzilla and cat .gifs to statistics. (Really, it’s fun.)
