Which U.S. banks hold the most deposits?

The interactive chart needs JavaScript. The numbers are on the chart's page.

JPMorgan Chase Bank held $2.82 trillion in deposits at the end of June 2026, the most of any U.S. bank, followed by Bank of America ($2.12 trillion), Wells Fargo Bank ($1.56 trillion) and Citibank ($1.55 trillion). Deposits are each bank's total, including any at its offices abroad, from its latest quarterly report to regulators; a bank is one legal company, so a group with several banks appears once for each.

Questions to discuss

Chart 2 of 2 · Road safety

Are U.S. roads getting safer per mile driven?

The interactive chart needs JavaScript. The numbers are on the chart's page.

In 2024 there were 1.19 deaths for every 100 million miles driven, down from 3.35 in 1980. The lowest rate was 1.08 in 2014; it jumped to 1.34 in 2020, when people drove less but deaths rose. Miles driven are the Federal Highway Administration's estimates.

How to read this chart

Each point is the number of people killed in traffic crashes for every 100 million miles Americans drove that year. Dividing by miles driven turns a count into a rate, so years when people drove more or less can be compared fairly.

Questions to discuss

  1. About what fraction of the 1980 rate is the rate in the latest year?
  2. In 2020 people drove less, but the rate went up. What could explain that?
  3. Why is deaths per mile a fairer way to compare years than the total number of deaths?
