Bear in mind 'other Christian' is also a halfway point for people on a journey away from faith altogether.
It can also be a transitional stage between one denominational affiliation and another, or between some other religion and Christianity, or between Christianity and some other religion. Or towards faith, although I'd imagine that's far less common than the reverse in most of the countries that posters on this site actually come from.
Far more 'other Christians' are made than born, and I would bet that far more who are made don't stay in that category than do.
