The Pew article 6 facts about economic inequality in the U.S. by Katherine Schaeffer (2/7/2020) provides the chart copied here (2017 data). One of the other facts mentioned in the article:
In 1989, the richest 5% of families had 114 times as much wealth as families in the second quintile (one tier above the lowest), at the median $2.3 million compared with $20,300. By 2016, the top 5% held 248 times as much wealth at the median. (The median wealth of the poorest 20% is either zero or negative in most years we examined.)
There are 6 (surprise) charts and the data is cited. Great QL article.
