Where can I find death or birth certificates to make sure the statistics are correct?
In West Virginia you can go to wvculture.org and search by birth, death, and marriage.
I guess that the answer to your question depends on where you live, or rather, where the person lived, whose birth or death certificate you are searching for.
Thank you for responding but I figured it out. I need to join a search site.
In the US -- this is a great site to answer questions like that
