A new study by researchers at Boston Children's Hospital found states with tougher gun control laws have fewer gun-related deaths compared to states that don't have strict gun laws.

This comes as the president is working with Congress to pass mandatory universal background checks for anyone who wants to buy a gun. 

The study compares states with strong gun measures to states that have more relaxed laws.  Study authors found in the states with stronger laws, there were 42 percent fewer recorded deaths from gun violence, with a significant reduction in gun-related suicides.

Researchers gathered the information from all 50 states from 2007 through 2010.

The recent gun violence across the U.S. has caused some states to write their own laws.

While it is not required by the state of Texas to conduct background checks, federal law does require licensed dealers in Texas to contact the FBI to initiate a background check.

In New Mexico some representatives say they are very close to introducing a bill requiring all gun buyers to go through background checks regardless of the seller. 

The measure would close a loophole that allows criminals and mentally ill people to buy guns at private gun shows.

In Texas, however, republican state representative has filed a bill that would make it illegal for law enforcement to enforce new federal gun laws.

The state of Texas does require people to have a state license in order to carry a concealed weapon.  In order to get that license, an applicant must first undergo a background check and a training course.  However, there have been cases where licenses were not revoked upon conviction of a felony.  This potentially creates another loophole for people to buy a gun because federal law does not require a background check for people who have a firearms license. 

While researchers do admit the study doesn't say what type of laws worked the best, they say they hope it will drive legislators to pass gun reform across the country.
