Historical Context
The concept of Personal Income (PI) has evolved significantly over time. Traditionally, it encompassed wages from employment; however, it now includes various income sources like investments, rental income, and government benefits.

Key Events

Personal Income is calculated by summing up all sources of income before taxes:
Where:

- \( D \) = Dividends and Interests
- \( R \) = Rental Income
- \( G \) = Government Transfers
- \( S \) = Self-Employment Income
