I want to know the answer to the following question:
What four areas have not been established as CDPs by the Census Bureau?
All the background I'm provided with is that "CDPs have not been established for these areas by the United States Census Bureau, except that seven CDPs were established for the Ketchikan-area neighborhoods in the 1980 Census (Clover Pass, Herring Cove, Ketchikan East, Mountain Point, North Tongass Highway, Pennock Island and Saxman East), but have not been used since.". Is that enough to answer the question?
Answer: no
