Donald Trump's travel ban by the numbers

US President Donald Trump's controversial travel ban has raised plenty of questions about the countries that made the list.

The decree from the 45th President puts in place a 90-day visa suspension for anyone arriving from Iraq, Syria, Iran, Sudan, Libya, Somalia and Yemen.

It also suspends the entry of refugees into the US for four months and imposes an indefinite ban on Syrian refugees.

Now, a conservative US think-tank has tallied the number of Americans killed in terror attacks on US soil by citizens of the seven banned countries.

The Cato Institute looked at the period from 1975 to 2015 and found:

  • From Iraq: 0
  • From Iran: 0
  • From Syria: 0
  • From Yemen: 0
  • From Libya: 0
  • From Somalia: 0
  • From Sudan: 0.

On the other hand, some newspapers have noted none of the Muslim-majority countries that have a Trump hotel, building or office are on the list.

This is despite the numbers being slightly different:

  • From Saudi Arabia: 2369
  • From the United Arab Emirates: 314.
  • From Egypt: 162.

The Cato Institute also points out that, including 9/11, the chance of an American being killed on US soil by a foreign terrorist over that 40-year period is one in 3.6 million per year.

The chances of an American on home soil being killed by a refugee in that period are 1 in 3.6 billion per year.
