AUTOMATED CODING RESEARCH AT THE CENSUS BUREAU

Daniel W. Gillman and Martin V. Appel

KEY WORDS: automated coding, industry coding, occupation coding

ABSTRACT

Research on improved methods of performing automated coding is being conducted by the Census Bureau. The Automated Industry and Occupation Coding System (AIOCS) was developed for the 1990 Census Industry and Occupation (I&O) Coding operation. It performed very well. AIOCS has now been certified for use in current surveys I&O coding processes as well. After the 1990 Census, research was begun to improve AIOCS productivity, reduce errors, and understand the algorithm. New methods of performing automated coding are also being analyzed. Some of the new methods can easily be applied to other coding structures. This paper details the research and results which have been done so far.
