The first global terrorism index finds that incidents of extreme violence are on the decline worldwide.
The index is produced by an independent nonprofit, the Institute for Economics and Peace.
The study says that terrorist incidents peaked in 2007 after increasing every year in the aftermath of the September 11 attacks in 2001.
But terrorism fatalities have decreased by 25 percent since then.
The index ranks 158 countries over the past 10 years. Only 31 of them have not experienced a terrorist attack since 2001.
The index lists Iraq, Pakistan, and Afghanistan as the countries most affected by terrorism last year. India is the fourth-most-affected nation.
The research says North America is least likely to suffer from terrorism while Western Europeans are more likely to encounter a terrorist attack.
