For the Republic of Ireland, Prospex uses District Electoral Divisions (DED) and ward boundaries as a building block to create catchments and territories. 

These are the smallest unit for which census data is available. Your own database can also be DED coded so you can map your own customer data.

Republic of Ireland small area population statistics (SAPS) census data offers the user the population knowledge of the area which can be compared with their own data. For example occupation, car ownership, sex, age ranges and tenure.

 
Because detailed postal geography is available for Northern Ireland and Prospex contains the boundaries of all postcode sectors and the locations of full postcodes, a single Prospex system can analyse and map data for the Republic of Ireland, Northern Ireland and Britain.
