In May, 2009, a USA Today survey conducted by the Gallup Organization*asked 608 U.S. adults age 50 and over if marriages between same-sex couples should or should not be recognized by the law as valid, with the same rights as traditional marriages.
Of those 608 U.S. adults age 50 and over, 35% responded that same-sex marriage should be recognized by the law as valid.
62.7% of them responded that same-sex marriage should NOT be recognized by the law as valid.
In the Fall semester, 2010, and Spring semester, 2011, I obtained the following responses to an anonymous online survey of 468 U.S. adults age 18-22.
Survey results based on 486 anonymous online questionnaire responses. Sample: U.S. adults, ages 18-22 inclusive, enrolled in at least one course at a large state university, who graduated from a public high school in the U.S.
