Sometimes a source refers to information from another source. You must cite both sources. Also:
Basic Citation Format:
Author, A., Author, B., & Author, C. (Date). Article title. Periodical Title, volume(issue), pages. Retrieved from db-name database.
Citation Example of an article within a company profile database:

Intext citation: (Epperson, 2010)
Citation Example of an analyst report retrieved from a database:

NOTE: In this case, SPINSscan is the author, Grocery Headquarters is the periodical. You do not need to cite Gale, Cengage Learning because it is an intermediary. No retrieval date is needed because it is a published article that can't be modified.

List all major variables used (i.e. income, automotive sales, etc). Identify the map or report used or referenced in the project.
Since there are two references with similar titles (Head of household...), use a longer title for the Intext Citation. The entire title is not necessary, but just enough for the reader to identify the report in the reference list.
