Survey statisticians in the National Agricultural statistics
Service (NASS) have long expressed concern about the complexity of
rules governing multiple frame surveys. The rules are based on the
structure of the NASS list sampling frame. Currently, the primary
name field defines the selected sample unit and may contain the
name of an individual, a combination of individual names, or an
The resulting rules for associating names with
land operated are many.
An alternative procedure, called the
"operator dominant" concept, proposes keying solely on the name of
an individual operator as the sampling unit for all operating
arrangements except those having a hired manager.
operations would retain the operation name as the sampling unit.
This technique was studied in eight States with alternative survey
indications generated in four States. Multiple frame rules were
simplified but additional reports were required of some operators.
There was an increase in data retained from list frame units with
a corresponding decrease in the area frame nonoverlap domain.
Survey indications changed less than one standard error from the
operational expansions with about as many increases as decreases.
An operational evaluation is planned for 1990-91 in nine States.
This study resulted from the combined efforts of members in several
others whose work contributed to development of the
alternative procedure include:
