Long description

This is a line graph with percentages from zero to sixty on the vertical axis, and dates in five-year intervals from 1839 to 1899 on the horizontal axis. A blue line representing the marks of brides descends from just under 50% in 1839 to about 3% in 1899. An orange line representing prisoners descends less noticeably, from 45% in 1839 to 25% in 1899 – with the sharpest decline in the 1880s and 1890s.
