Population, 'c. of the United States.
A valuable paper on the population of the United States, in reference to the census of 1830, is published in a late western paper. It is calculated, from the known ratio of increase since 1790, when the number of inhabitants was 3,816,450 that at the next census, the number will amount to 12,520,500-giving an addition in 40 years, of 3,604,044. The following facts are deduced from this estimate:
The population of the United States has in forty years been trebled.
Two states which in that time have received the greatest accessions of numbers are, New York, Ohio, and Pennsylvania.
That the middle and western non slave holding states, being N. York and N. Jersey, Pennsylvania, Ohio, Indiana, and Illinois, have, in this space of time, multiplied their people more than five fold, and contain now more than half the inhabitants of the United States.
That the southern slave holding states so called, Maryland, Virginia, N. Carolina, S. Carolina, Alabama, Mississippi, and Louisiana, have in that period, only doubled, and from nearly half, are reduced to less than one third of the whole population.
That in reference to the most important points of national policy to protection of American industry, the centre [sic] of power has been entirely changed.
