Four questions to ask of any dataset before you start manipulating variables:
1. Why was this data collected?
2. Who cares about the data and why?
3. Who uses/used the data and how?
4. What or who is missing from the data?
Consider the following documents:
a. Article 1, Section 2 of the United States Constitution
b. Census Act of 1830
c1. Microform image of half page of a census schedule (that happens to include John Quincy Adams!), plus re-creation of 1830 census schedule to show categories
c2. Abstract of the Returns of the Fifth Census (published 1832)
d. Raleigh Register. "Ratio of Representation." Carolina Observer [Fayetteville, North Carolina] 22 July 1830: n.p. 19th Century U.S. Newspapers. Web. 10 Feb. 2016.
e. Ames. "'Reduction' or 'No Reduction'." Augusta Chronicle [Augusta, Georgia] 7 Aug. 1830: n.p. 19th Century U.S. Newspapers. Web. 10 Feb. 2016.
f. "Census of Boston." Boston Courier [Boston, Massachusetts] 30 Aug. 1830: n.p. 19th Century U.S. Newspapers. Web. 10 Feb. 2016.
