Abstract
Janet L. Williams, Eugene F. Brown, and Gary R. Zion (1993) "The Challenge Of Redesigning The
Consumer Price Index Area Sample", Proceedings of the
Section on Survey Research Methods, American Statistical
Association, forthcoming.
The sample design for the U. S. Consumer Price Index (CPI)
is a multistage one which is revised every ten years. The
first stage consists of selecting primary sampling units
(PSUs) which are either Metropolitan Standard Areas (MSAs)
defined by the Office of Management and Budget or are defined
by BLS in the nonmetropolitan areas. The selected PSUs are
also used in the Consumer Expenditure Survey (CE) and the
Consumer Point of Purchase Survey (CPOPS). This paper
describes the recently completed PSU selection process for
the 1998 CPI Revision. Also detailed is the PC software
developed and used to implement this process which includes
nonmetropolitan PSU definition, selection of stratifying
variables, Keyfitzing and controlled selection. The paper
discusses how conflicting and uncertain demands were handled
in the design. One demand was the necessity of selecting the
sample PSUs before a decision was reached on the possible
expansion of the CPI household frame.
