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.
that may be what the article stated but surely you do not think that only 4.8% of all who have adopted are opposite sex couples
do you?
still it is strange to be so upset because I posted a .5 instead of .8
