s of immigrants in
the United States in 1840: 722,000
Total number of immigrants in the United States since 1790, and their
descendants in 1850: 4,350,934

The following, we think, may be considered an approximate estimate of the
population of the United States, in 1850, classed according to their
descent from the European colonists, previous to the American Revolution,
also from immigration since 1790, from the people who inhabited the
territories acquired by the United States (Louisiana, Texas, &c.), and
from Africans:

Descendants of the European colonists, previous to 1776: 14,280,885
Ditto of people of Louisiana, Texas, and other acquired territories:
1,000,000
Immigrants since 1790, and their descendants: 4,350,934
Descendants of Africans: 3,626,961
Total population: 23,258,760

It will be seen from the above, that the total number of immigrants
arriving in the United States from 1790 to 1850, a period of 60 years, is
estimated to have been 2,759,329--or an average of 45,988 annually for the
whole period. It will be observed also that the estimated increase of
these emigrants has been 1,590,405, making the total number added to the
population of the United States since 1790, by foreign immigrants and
their descendants, 4,350,934. Of these immigrants and their descendants,
those from Ireland bear the largest proportion, probably more than one
half of the whole, or say two and a half millions. Next to these the
Germans are the most numerous. From the time that the first German
settlers came to this country, in 1682, under the auspices of William
Penn, there has been a steady influx of immigrants from Germany,
principally to the Middle States; and of late years to the West.

The density of population is a branch of the subject which naturally
attracts the attention of the inquirer. Taking the thirty-one States
together, their area is 1,485,870 square miles, and the average number of
their inhabitants is 15.48 to the square mile. The total area of the
United States is 3,280,000 square miles, and the average density of
population is 7.22 to the square mile.

From the location, climate, and productions, and the habits and pursuits
of their inhabitants, the States of the Union may be properly arranged
into the following groups:
