Death place

Recently, we noticed that you're often marking death certificate as the death source, but you don't have a place of death.

If you're getting the information off a death certificate, then there MUST be a place of death, even if it's only the state. To register a death (that is, get a death certificate), you must know where the person died. So, if you don't know where the person died, then don't mark death certificate as the source.
