A new poll that found most believe this year was worse for the world than last year reveals mass shootings and attacks weighed heavily on the minds of Americans in 2015.

The Associated Press-Times Square Alliance poll found the most important events to Americans in the past year were the shootings in San Bernardino, California, plus shootings in South Carolina, Oregon and Tennessee.

Close behind came the Paris attacks and Islamic State group atrocities.

Americans also are much less likely than they were a year ago to believe that the current year was better for the United States — only 17 percent compared with 30 percent a year ago.

The poll of 1,020 adults was conducted online Dec. 11-13, with a 3 percentage point margin of sampling error.
