The Geographic Services Unit (GSU) is the arm of the Statistical Institute of Jamaica (STATIN) that has responsibility for mapping for all censuses and surveys. Accordingly, the unit carries out several functions to achieve this mandate, including the production of census and survey maps and descriptions, the preparation of graphs and charts to illustrate published census and survey results, as well as for defining and delimiting urban places particularly as they relate to the norms, criteria and the supporting justification for the demarcation across the island.In this regard, a hierarchy of statistical divisions are created and maintained with respect to developments which can affect the delimiting of each geographic unit.In addition, the unit provides advice on diverse geographic issues to public and private sector entities.

The GSU prepares Enumeration District (ED) maps (click here to view an Hanover West 24 ED  map) for data collection.An Enumeration District is the smallest geographic unit into which Jamaica is divided to facilitate data collection for censuses and surveys.The Geographic Services Unit is engaged in the use of GIS to capture, prepare and store maps that cover the entire island.
