That means that the UK has actually provided about 20% more aid as a fraction of their GDP (0.212%) compared to the US (at 0.173%).

I believe Canada allows religious marriage (you don’t have to get a marriage license in that case, it’s not a civil ceremony).

Edit: you can also have a civil marriage ceremony, which is also legally valid

That is true in the US, but there are many counties where religious marriage is legal marriage.
