Not surprised faith was a priority in the US. People of faith often spend much of their social time in their church activities, volunteering, bible study, choir, etc. I am lucky to be in good health so don’t think a lot about it. But I pray daily and am appreciative of my faith. And as a Christian, we believe in the resurrection and afterlife, which is kind of a big deal. So, not surprising to me at all that faith made one of the top sources of meaning. I know my Jewish and Muslim neighbors feel the same.
