Searching for death causes

IMPORTANT:  Please remember that even when you get a great indexed death certificate on Ancestry, you still have to look on Family Search for the image of the certificate in order to  get the death cause.  Death causes are critical to a project about health and mortality, so if the causes are available online, we want to make sure we get them.  

These are a few of the states that have great images available, mostly linked through Family Search except where noted:

Missouri (Missouri Digital Heritage, death certs between 1910-1966)

West Virginia

Michigan

Indiana

Kentucky

Ohio

Pennsylvania

North Carolina

District of Columbia
