MEMOIRS 
OB THE 
AMERICAN ACADEMY. 
I. 
Remarks on Longevity and the Expectation of Life in the 
United States, relating more particularly to the State of New 
Hampshire, with some Comparative Views in relation to 
Foreign Countries. 
BY J. E. WORCESTER, A. A. S. 
Tur inquiry respecting longevity and the expectation of life, 
in the United States, compared with that of other countries, has 
never been very thoroughly pursued. We frequently meet with 
casual remarks or a short essay respecting some branch of the 
inquiry, but no one is known to have attempted an extended 
comparative view of the subject. It is to be regretted that there 
is a want of sufficient data for furnishing so full and satisfactoe 
ry views of it as could be desired ; and particularly that the 
census of the United States has hitherto been taken in such a 
form, as to be almost useless in the investigation. And a leading 
inducement with the author of this communication, in preparing 
and offering it to the Academy, has been the hope, that, by calling 
the attention of others to the subject, an improved mode of taking 
the census may in future be adopted.
