This chart ranks Am Law 200 firms by the percentage of their U.S.-based lawyers who performed more than 20 hours of pro bono work in 2018. Calculations are based on lawyer counts as of Dec. 31, 2018.

We define pro bono work as legal services that a law firm has donated to organizations or individuals that could not otherwise afford them. We do not include work  that was done by paralegals or summer associates, nor time spent on bar association work, nor on nonlegal work for charities or on boards of nonprofit organizations.
