A frame is a representation of a population, used to implement a sampling strategy as, for example,

1) a list frame that lists the identifying units in the population-for instance, a list of all the lakes in the United States between 10 and 2000 ha - or
2) an area frame that consists of explicit descriptions of a partition of the areal extent of an areal universe - like the NASS frame.
