How did the black population change between 1910 and 2010?

Show/Hide Instructions...

Instructions:

Note about maps: 1950 data is not represented on these maps because county level data for that year is not available in Social Explorer.

  1. Make a prediction, how do you think the African American population will change between 1910 and 1970?
  2. Flip through all of the slides. Use examples from the maps to show how the population changed over time.
  3. Make a table to compare the changes in the black population in Desha County, Alabama to the changes in Cook County, Illinois between 1910 and 1970. Use the hover tool to collect specific information about each county each year: number and percent of the population. Make a line graph to represent the changes in the black population in each county.
  4. Use the information in the table and graph to describe the changes in the black population in each county from 1910 to 1970. To calculate the absolute change, subtract the 1910 figure from the 1970 figure. To calculate the relative change, divide the absolute change by the 1910 figure.
  5. You used maps, tables, graphs, and calculations to describe the changes in a population over time. Describe the advantages and disadvantages of each representation.

Use the bubble maps on slides 1 -6 to describe how the concentration and distribution of the black population changed over time.
