This HPSA shortage list notice will tell you all. When infants are on the move, they leave all the handprints you don't want everywhere, but neat little footprints are the important prints for infants. Footprints like fingerprints remain unchanged in a person's life and adult footprints can provide a fast and accessible form of identification when fingerprint and DNA identification take time and are more expensive.

The United States has fought in 12 wars, involving 41,902,000 participants of which 1,089,200 died. Included in each issue is the Name, death date, and age of the Last Veteran, Last Widow, and Last Dependent of each as applicable to each war since the Revolutionary war. This August 20, VA press release says there are about 3,200 Living WWI veterans, and about 900 WWI veterans receiving VA benefits. I think contacting the VA offices would be the only way to resolve these number conflicts, but the sources are quite interesting.
