Arizona, having an area of 113,000 square miles, was organized as a territory in 1863 and appeared in the federal census reports for the first time in 1870 with a population of 9,658. From 1870 to 1890 its growth in population was rapid, increasing a little more than four times during the decade 1870-1880 and doubling during the succeeding ten years.
