This note was revised on September 30, 2020 to correct the second column of Panel B of Table B, which erroneously reported the mean of inheritance assets that were received or expected. The corrected table reports the mean of expected inheritance assets only.

Understanding how economic growth diffuses across the population is a key economic issue. Indeed, this question has inspired renewed debate about how to characterize wealth and income distributions in the United States, particularly with respect to the extent of concentration at the top. Most of this work has described an increase in recent decades in concentration, raising concerns that broader segments of the population are not sharing in economic gains (Bricker, Henriques, Krimmel, and Sabelhaus, 2016; Saez and Zucman, 2016; Piketty, Saez, and Zucman 2018; though see Auten and Splinter, 2020, for contrast).
