Worldwide, almost a third of all births aren't registered. Nationally, registration rates vary widely, from 3 percent in Somalia to 100 percent in Bhutan. In some cases, that's because birth certificates don't seem useful to parents. For someone who lives in a remote part of a country that doesn't provide any obvious citizenship benefits, there's not much of an incentive to bother with registering a child.
For a child born in a foreign country and adopted by a U.S. citizen, a birth certificate may be available from the state where the adoption was registered (generally the state where the parent(s) resided during the adoption). If the adoption was not registered in the U.S., you may need to speak with someone at the foreign embassy for the country where you were born in order to get a copy of your birth record. In these cases, a certificate of naturalization may be necessary to prove U.S. citizenship.
