Even in an increasingly secular culture, about half of U.S. adults still bow their heads to pray when they sit down to a meal, according to a new report from The Washington Post and Kaiser Family Foundation.

The data revealed that saying grace at least a few times each week is a tradition people widely practice across the country, from the north to south, and in rural, urban and suburban areas.

Republicans are more likely than Democrats to pray before meals (62 percent vs. 43 percent). And more black Americans (80 percent) and Hispanic Americans (60 percent) regularly say grace at mealtimes than white Americans (40 percent).

Among those identifying as Christians, about 60 percent of Protestants and 52 percent of Catholics frequently pray before eating.
