How I created the visualization: I received a copy of “W.E.B. Du Bois’s Data Portraits” for Christmas, and when I saw this contest, I knew that I wanted to use the Georgia map visualization, Plate 20. I also wanted to pull in data from Du Bois’s Plate 5 on the Black population in each county, but those were given as ranges rather than as specific numbers. I decided to try to track down Census data from that time. Because 1890 Census data is unavailable, I used 1880 Census data. I accessed this on IPUMS-USA, where I created a data extract that included State and County ICP, farm status, and race. Because I requested the full Census, this data is not allowed to be republished. I used the ipumsr package in R to read in the data from the extract and take the relevant subset of it. Then, I used Excel to make pivot tables to get the number of black individuals and households, farm and nonfarm, for each county code. I looked up the ICPSR county codes for Georgia to find the corresponding county names. I downloaded the map shapefiles for Georgia counties from The Newberry Library, Atlas of Historical Records. Then, I used Tableau to map the counties. I used the high res file of Du Bois’s Plate 20 from the Library of Congress to record the acres of land owned by Blacks in 1899 in each county. After having done this, I came across the Bulletin of the Department of Labor No. 35 - July, 1901, and on page 661 there are estimates for the Black population in each county in 1890. I used these values instead of the 1880 Census values, since they are much closer in date to the data from Plate 20 (1899). I decided to keep the percent farm / nonfarm data, even though it is for 1880, as it seemed interesting and relevant. Finally, in Tableau, I made the interactive maps based on the user’s choice of variable. The interactive maps can be seen here: https://public.tableau.com/profile/leah.dorazio#!/vizhome/BlackDataProject2019/Plate20_plus . The iframe and embed codes can also be found there.
