The top decile of the wealth hierarchy already owned between 80 and 85 percent of all wealth at the beginning of the nineteenth century; by the turn of the twentieth, it owned nearly 90 percent. The top centile alone owned 45–50 percent of the nation’s wealth in 1800–1810; its share surpassed 50 percent in 1850–1860 and reached 60 percent in 1900–1910.
