How many babies were given up for adoption?

That depends on the year, month, day etc. Are you wanting to know how many for this year only? If so then visit Adoption Crossroads, a site owned and operated by Joe Soll, he has a running tally of children adopted that increases hourly at the top of his site's header.

All time... its hard to say because the govt. won't release those statistics. You also need to take into consideration if they are international, domestic or private or foster care adoptions. So many different things to take into consideration its hard to say.

My estimate is definitely into the millions of all time, for SURE.
