The aggregate rates of increase diminished regularly during each successive census decade from 1790 to 1840; but between 1840 and 1850, it increased over three per cent., corrections being made for the admission of new territory.
During the last census decade, Wisconsin increased in population 891 per cent., this being the largest percentage of increase which has occurred in any part of the Union during any decade in the last fifty years. Michigan stands next in order, and gained 574 per cent., between 1830 and 1840, and Indiana gained 510 per cent. between 1810 and 1820. In some of the Eastern and Middle States, however, the ratio of increase is much less, being in Connecticut only 0,28 per cent. during the last census period, and in Delaware there was even a decrease of 0,14 per cent. between 1810 and 1820.
