CENSUS ENUMERATION. 1  Census enumeration is a key census phase and the success of the census depends on it being done quickly, efficiently and with proven methods. This chapter describes different methods which can be applied in agricultural censuses and surveys, such as sampling (see also Chapter 7), interviewing, etc.
In this case an enumeration may be defined as follows: 1  As a bijective mapping from S to an initial segment of the natural numbers. 2  This definition is especially suitable to combinatorial questions and finite sets; then the initial segment is {1,2,..., n } for some n which is the cardinality of S.n some contexts, such as enumerative combinatorics, the term enumeration is used more in the sense of counting â with emphasis on determination of the number of elements that a set contains, rather than the production of an explicit listing of those elements.
