There is a generational divide on this issue. Young Americans (those ages 18-29) are some of the strongest proponents of allowing gay and lesbian couples to marry. Seventy-two percent of them support it, as do a majority --albeit a smaller one-- of Americans ages 30-44. However, support for same-sex marriage drops to 44 percent among those who are age 45-64 and even further to just a third of Americans age 65 and over. In fact, 56 percent of seniors oppose permitting same-sex couples to marry.
The CBS News Poll also finds more women (53 percent) than men (48 percent) think same-sex marriage should be legal. Women voters were instrumental in getting the ballot measures legalizing same-sex marriage passed. According to exit polls conducted in each of the three states, majorities of women approved of the same-sex marriage initiatives, while men opposed them.
Nationwide, opinions on same-sex marriage also differ by marital status. Married Americans are divided in their views, while 57 percent of unmarried Americans support allowing same-sex couples to marry.
As might be expected, there are differences by political party. Most Democrats think it should be legal for same-sex marriage couples to marry, while most Republicans do not. Fifty-five percent of independents support marriage for gay and lesbian couples.
The actual questions as whether "Same sex marriage should be legal or not legal." This is a change in methodology for CBS News, in that prior to May 2012 they used to ask the "tri-partite" question which included a civil unions option (and options supporting pro-marriage equality and anti-marriage equality).
The poll was conducted November 16-19, 2012 with 1,100 adults and has a margin of error of 3 percentage points.
