The ISE (Economic Situation Indicator) and the ISEE (Equivalent Economic Situation Indicator) are two parameters that allow us to briefly assess the economic conditions of families applying for subsidized social benefits or facilitated access to public utility services, i.e., benefits whose provision depends on the applicant's economic situation.

The ISE concerns the family's economic situation as a whole.

The ISEE, instead, arises from the relationship between the ISE and the parameter derived from the Equivalence Scale based on:

• to the number of members of the family unit
• to the type of family unit: with disabled members, a single parent, etc.
