Abstract:	The geocoding system, an alternative system of specifying geographical location, eliminates many of the difficulties associated with an areal unit referencing system. Instead of defining boundaries it is possible, using this system, to take fundamental units such as houses, factories, offices, etc., for which information may be required, and give each an XY co-ordinate location code. Each of these codes, which can be given in latitude and longitude terms or more conveniently as national grid references, serves as a location al reference for information collected at a specific point. Any system of areal boundaries is rendered redundant. A certain amount of interest has been shown in using the geocoding system in the Nigerian population census (Adeokun 1971, Richards 1970, 1972). This paper, which draws on experience gained in field trials carried out in Ibadan in 1970, aims to give a clear picture of the practical issues at stake in utilizing the technique under Nigerian conditions.
