Macroeconomics and microeconomics are distinguished by their scale of analysis. Macroeconomics examines the economy as a whole, focusing on aggregates. For example, it studies the total output of all producers rather than a single firm's production, the level of unemployment in the entire economy instead of in a specific local labor market, and inequality across the whole population rather than between two individuals. In contrast, microeconomics focuses on the individual components within the economy.

Comparison of Macroeconomics and Microeconomics

The distinction between microeconomics and macroeconomics can be compared to a similar division in life sciences. A microeconomist is like a cell biologist, who studies the fundamental units of a complex system (cells). In contrast, a macroeconomist is like a medical researcher or anatomist, who examines the system as a whole (the human body).
