I had a question today about which countries have reservations to the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) and which are signatories without reservation. I have not found an easy chart or list to answer this, but I have found some articles about regions, such as one about North Africa and the Middle East. The only way to answer this that I see so far is go through the country reports at the CEDAW website.
Looking at the list, I see this statement about the United States of America: "not a party to CEDAW convention." The convention first passed the United Nations in 1979. We have had time to sign on. How sad!
