Some changes of this character have been taking place in our New England population, which we purpose here briefly to notice. In the earlier history of New England there were few changes in the residence of her people. As agricultural pursuits constituted their principal occupation, the same farms and lands continued to a great extent in the same families from generation to generation. Prior to the Revolutionary War very little emigration took place out of New England. In the early part of the present century many persons removed to New York and some to Ohio. From 1810 to 1830 this emigration continued steadily to increase, not only to those States but to the States and Territories farther west. To such an extent had this emigration been carried on that, in 1840, the United States census reported nearly half a million of persons born in New England who were living in other States.

While we have no means of ascertaining the exact number removing from New England, during any one year or period of time, the United States census gives, every ten years, the birthplace of all people residing in every State at the time the count was made. The census of 1880 reports that the whole number born in New England
