• The unit of observation or analysis is a group of study subjects aggregated over sub-regions and/or temporal intervals
• The data often consists of disease frequency estimates or case/population-at-risk counts for each group

 

• The sub-regions can be identified with boundary data or x-y centroid coordinates
