You are in a wad because I typed .5 instead of .8??
No, because you changed the entire meaning of their statistics.
“Comparatively, only 4.80% of opposite-sex couples have adopted children.”
That means that of all opposite couples, 4.8% have adopted children.
And opposite sex couples only make up 4.8% of households who have adopted.
That means that of all couples that have adopted, 4.8% are opposite sex.
