From this view of the result, it should seem 

 that the middle and northern states were the 

 most favorable to longevity, and the preserva- 

 tion of life : And that the southern states were 

 the most favorable to a rapidity of productioiv, 

 and increase. Whether these circumstances 

 will not balance each other, and produce an 

 equality in the period- of doubling, cannot be 

 determined v/ithout further observations. In 

 Massachusetts, the period of doubling cannot be 

 far from tv/enty four years and three months. 

 What this period is in other states, must be de- 

 termined either from actual obscrvati(3n, or by 

 ascertaining the ratio which the deaths bear to 

 the births. If the enumeration which is to be 

 taken in the year 1800, should be as particular 

 with respect to the females, as the last was witli 

 respect to the males, it would enable us to as- 

 certain several particulars in this part of the nat- 

 ural history of man, which cannot be determined 

 without another enumeration. 



It has been generally supposed, that the in- 

 crease of mankind is most of ail rapid, in a new 

 Qountry ; and that it is in the new settlementSj
