Why macroeconomics is called aggregate economics?

Macroeconomics is referred to as aggregate economics because it studies the economy as a whole, focusing on total output, employment, inflation, and overall economic growth rather than individual markets or sectors. It examines broad phenomena such as GDP, national income, and overall price levels, which represent the collective behavior of all economic agents. By analyzing these aggregates, macroeconomics seeks to understand the interrelationships and dynamics that drive the economy at a national or global level.
