negro.png This image displays a line graph plotted on a white background with a light gray grid. The chart tracks a specific dataset over time. At the top center of the image, there is a legend consisting of a small blue square followed by the text "Negro". This indicates that the blue line represents data related to this term. The horizontal axis (x-axis) at the bottom represents years. It begins in 1850 and extends slightly past the year 2000. The years are marked with labels every ten years: 1850, 1860, 1870, 1880, 1890, 1900, 1910, 1920, 1930, 1940, 1950, 1960, 1970, 1980, 1990, and 2000. The vertical axis (y-axis) on the left represents a percentage value. The labels start at the bottom with "0.00000%" and increase in increments of 0.00100% up to the top label, which is "0.00900%". A single blue line traces the data across the graph: - From 1850 until roughly 1930, the line remains very low and relatively flat, hovering just above the 0.00000% mark, slowly rising to about 0.0015%. - Between 1930 and roughly 1945, there is a sharp upward trend. The line climbs steeply from approximately 0.002% to a local peak of around 0.0075%. - Following this first peak, the line drops sharply until about 1950, reaching a low point near 0.004%. - From 1950 to roughly 1968, the line rises again, climbing steadily past the 0.005% and 0.006% marks. - The graph reaches its absolute highest point around the year 1970 (specifically late 1960s). At this peak, the blue line extends slightly above the top grid line of 0.00900%. - Immediately after this peak, there is a steep decline. By 1980, the value has dropped to roughly 0.003%. - From 1980 to roughly 1995, the line stabilizes and fluctuates slightly around the 0.002% mark. - Finally, from roughly 1995 to the end of the chart (past 2000), the line shows a slow, gradual decline, ending just above the 0.00100% level.
