Two types of PBRS have been used: site-based (PBRS I) and area-based (PBRS II). Site-based PBRS deals with a suite of pre-determined sites and places them in their socio-economic, environmental and combined context. Area-based PBRS, meanwhile, records the characteristics of a large geographic area, allowing variations in an area’s socio-economic and environmental personality to be shown.

Whichever PBRS type is used, its fundamental ethos remains the joint assessment of the social, economic and environmental attributes of a site or area.

The actual attributes measured in a PBRS are determined by the aims and objectives of the particular project the PBRS is being used for. That is to say, they are not fixed but can be tailored to the specific needs or areas of interest a project wishes to examine.

This section of the PBRS website will help you learn more about the architecture of the system, and about the smart indicator sets, thematic data layers, and geographical information systems (GIS) that have been used to build the PBRS.
