Geocoding Procedure To find Geographic Identifiers in the Housing Component of the Consumer Price Index
Abstract
This paper gives an introduction to the Housing component of the Consumer Price Index (CPI), outlines the steps taken to geocode housing units for use in the CPI, and discusses uses of geocoded housing units. The purpose of geocoding is to find a geographic identifier called a Census Block Group Number for housing units. U.S. Bureau of Labor Statistics Statisticians will use this identifier for weighting, sampling, and identification purposes. The software used is ArcView 9 created by ESRI. ArcView 9 is GIS software used primarily by geographers; it is beginning to find prevalence in statistical realms. Other software used is SAS and ESRI's Map Loader.
