If you take a step back and follow the trend of almost any country's international adoptions you'll likely see them quickly speed up and then quickly, sometimes drastically, slow down.
This week, the Ethiopian Ministry Of Women's Affairs (MOWA) proposed changes in the number of adoptions to be processed from 50 per day to 5. "Given MOWCYA's curent caseload, the US Embassy anticipates that this change could result in an overall decline in case processing of some 90%." adoption.state.gov
I just read that in sub-Saharan Africa (which constitutes most of Africa) 1 out of every 8 children is an orphan.
"Of the 143 million orphans worldwide, more live in Ethiopia than in any other country in the world."
