WASHINGTON — Nearly one year after a gunman killed 20 children and six adults at Sandy Hook Elementary School in Newtown, Connecticut, polling data shows that although support for additional gun control legislation is still strong, less people are supporting such a push.

A survey of 843 adults conducted by ORC International for CNN concluded that while 49 percent say they support new gun control laws, the number is down six percentage points from January, a few weeks after the incident in the small Connecticut town.

In the current round of polling, 50 percent of respondents said they oppose such legislation, and the results indicated that people on both sides of the fence are less intense about their positions than a year ago.

Geography also plays a part in determining support or opposition of new gun control measures.

"Demographically speaking, the drop in support for stricter gun laws is mostly based on where people live, with a 10-point decline in the Midwest and a 15-point drop in urban areas having a lot to do with the overall decline nationally," CNN Polling Director Keating Holland said in releasing the poll. "Two-thirds of people who live in big cities supported stricter gun control laws in the weeks following Newtown; now that figure is down to a bare majority. And while support for new gun laws is down in all regions of the country, it has fallen further in the Midwest."

In reaction to the Newtown shooting, Connecticut adopted a bipartisan set of new gun restrictions which rank among the toughest in the nation.

The legislation, passed by the state legislature and signed by Gov. Dannel Malloy, added more than 100 firearms to the state's assault weapons ban and creates what officials have called the nation's first dangerous weapon offender registry as well as eligibility rules for buying ammunition. The law also requires background checks for all firearms sales in the state, including previous exceptions to the law such as transactions at guns shows and private sales.

On the federal level, Senate Republicans with the support of some rural-state Democrats rejected a bill in April expanding background checks for gun purchases, even amid high public support, The National Rifle Association and other gun-rights advocacy groups have adamantly opposed any new gun-control regulations.

The telephone survey took place between Nov. 18-20 and carries a 3.5 percent margin of error.
