A measure that determines the magnitude of the same phenomenon in two different periods. Depending on whether the indices are calculated for a single unit or for a set of unit entities, we divide it into individual and group indices, and among group indices we distinguish aggregate indices (eg Laspeyres Index and Paaschi Index).

• Aggregate index of prices according to the Laspeyres formula
• Aggregate index of prices according to the Paasche formula
• Aggregate value index
• Index of magnitude relations
• Team index with fixed structure
• Team index with variable structure
• Team index of the impact of structural changes

• Individual indices
