Many adults, especially millennials, don't know about some of the key events in the Holocaust, per a survey released today, Holocaust Remembrance Day, by the Claims Conference.

A key stat: 41% of American adults don't know what Auschwitz — the Nazi concentration camp in Poland — was. That rises to 66% for millennials (ages 18-34) alone.

More findings:

  • 31% of Americans — and 41% of millennials — think 2 million or fewer Jews were killed in the Holocaust. In reality, 6 million were killed.
  • 52% of Americans incorrectly think Adolf Hitler took power by force, reports the New York Times from Claims Conference's survey results.
  • 80% of Americans have never visited a Holocaust museum.
  • 96% of respondents believe that the Holocaust happened, and 93% believe it should be taught in school.

The United States' alarming rise in coronavirus cases isn't due to increased testing — particularly not where cases have grown fastest over the last month.

Why it matters: The U.S. doesn't yet know what it looks like when a pandemic rages on relatively unchecked after the health system has become overwhelmed. It may be about to find out.

Because of the coronavirus and people's buying habits moving online, retail stores are closing everywhere — often for good.

Why it matters: Malls are going belly up. Familiar names like J.C. Penney, Neiman Marcus and J. Crew have filed for bankruptcy. Increasingly, Americans' shopping choices will boil down to a handful of internet Everything Stores and survival-of-the-fittest national chains.
