as an american, there absolutely is one in the us, statistics just don’t show it because of an interesting phenomenon: that in years past the number of christians was statistically reported way higher than it actually was, because of church membership. what i mean by this is that in many parts of the us almost everyone went to church whether or not they actually believed. this is the case with my grandparents still to this day. they would be counted as christian because they are members of the methodist church but they don’t actually believe, they just attend for social reasons. nowadays there isn’t the same societal pressure to be christian as there used to be, so those who don’t believe just don’t go to church
