Liberia 1966 Agricultural Survey

"[T]he 1966 agricultural survey in Liberia used an outdated frame prepared for the 1962 population census. For this census, 1200 enumeration districts had been mapped out. A post enumeration study revealed that physical features of the enumeration districts had changed so much that 17% of the localities, 12% of the structures and 18% of the population were omitted from the enumeration." (Kiregyera 1982, pp.308-9.)
