How to stay safe during a school shooting in Chicago

More than 2,000 people have been killed and hundreds more injured in mass shootings in the US since the election of Donald Trump in November, according to a new study.

The study, conducted by the Chicago Tribune, tracked more than 2.5 million school shootings in US history.

The report also found that gun deaths in the United States have increased by more than 100 per cent since 2008, with the average gun death per year since 2008 up to 10,600 per year.

“Our data show that there are fewer guns in the hands of people in the general population than at any time since the early 1990s, with one in three Americans having a gun in the home, and the number of guns in America at the start of this century at less than half of what it was before the election,” the study said.

The researchers also said the US had the highest number of mass shootings since the mid-1990s in terms of the number and number of deaths.

It comes after the number one-most common type of mass shooting in the country – a school massacre – has been reduced from 1,000 per year to under 100 in the past decade.

The findings come as Congress considers new legislation to tighten gun laws following the mass shooting at a Connecticut elementary school in January.

The National Rifle Association has called for tighter restrictions on guns, and is also pushing for a ban on high-capacity magazines.

The gun control bill is expected to be introduced next week.

The gun violence prevention initiative has been championed by Senator Dianne Feinstein, Democrat of California, and has bipartisan support, including the support of former President Barack Obama.

However, the legislation has been opposed by the National Rifle Assn.

and the American Academy of Pediatrics, which have said the measure would lead to a flood of guns and encourage people to get them.

In the report, the researchers found that the number who were killed by a mass shooting had increased by nearly 50 per cent in the five years after the Newtown, Connecticut, shooting in December 2012, when 26 people died.

Among the people killed by mass shootings, a quarter had been shot at least once before the shootings.

A quarter had witnessed mass shootings at least twice before, while one in four had been involved in at least one mass shooting.

The research team also found a significant rise in the number in the four years before the shooting, when only one in seven people had been at a school when a mass shooter killed 12 people and injured 27 others.

The number of school shooters, meanwhile, had been steadily declining since 2008.

The average number of people killed in school shootings had dropped by 2.7 per cent each year from 2007 to 2015.

It has also decreased by 0.8 per cent per year from 2008 to 2015, the report found.

“We found that although the number per year of school shooting victims dropped, there was a significant increase in the rate of people who died in the incident,” the researchers wrote.

The Chicago Tribune said the study showed that while there had been a reduction in gun violence since 2008 in the first year after the election, the data indicated that mass shootings had continued to rise since then.
