A week after two landmark gay-marriage cases were argued before the Supreme Court, the progress of gay marriage advocates has been evident in a recent swath of public opinion polling.
The Pew Forum on Religion and Public Life recently published seven charts that show trends over 13 years of polling on same-sex marriage.
According to the polling, not only is support for same-sex marriage growing across different demographics, but it also runs especially high in groups that are growing the fastest.
In the past 13 years, opposition to gay marriage has declined 13 percentage points.
Today, seven in 10 millennials support same-sex marriage, meaning the shift will continue to trend upward.
Support for same-sex marriage is also heavily based on religious sentiment. Religiously unaffiliated people — the largest and fastest growing sect of Americans — support gay marriage by a four-to-one split.
