agriculture may be traced, and the steps which mark its decline, 
either in the individual provinces of a state, or in the aggregate 
of a country at large, may be readily and satisfactorily measured. 
So, also, the dawn of trade, and its gradual enlargement; — the 
feeble beginnings of the arts, and their rapid progression, when 
quickened by the active springs of commercial enterprise and 
speculation, — all have an influence on population; and their 
proportional effects become manifest, by accurate periodical re- 
turns. In some divisions of a country, for example, agriculture 
may advance with rapidity, and make the steps, by which com- 
merce ascends, appear feeble and unimportant. In other States, 
commerce and manufactures may exhibit strong proofs of ma- 
turity and vigour, but the arts connected with agriculture dis- 
play every symptom of languor and decay. These varied 
changes, with many other mutations of a smaller kind, may be 
satisfactorily estimated, when statistical surveys are well con- 
ducted, and all the elements necessary for undertakings of the 
kind are faithfully and properly introduced. 
To estimate, in a satisfactory manner, the various degrees in 
which agriculture, commerce, and manufactures prevail, in the 
different provinces of the United States, the following table has 
been computed, from the population returns for 1820, by 
making the number of persons in each of the classes here al- 
luded to, proportional to a population of 10,000 persons; and 
to render the comparison convenient, the numerical results have 
been arranged in descending series, with the name of each state 
opposite to its appropriate representative number.
