YEAR. POPULATION. RATIO OF INCREASE

1790 3,929,827

1800 5,305,937 35.02 Per Cent.

1810 7,239,814 36.45

1820 9,638,131 33.13

1830 12,866,020 33.49

1840 17,069,453 32.67

1850 23,191,876 35.87

1860 31,443,790 35.58

"This shows an average Decennial Increase of 34.69 per cent. in
population through the seventy years from our first to our last census
