Economics does not have one fixed number of branches, because different books and schools classify them differently. A common basic split is into microeconomics and macroeconomics , while many broader lists also include fields like international economics, public finance, development economics, health economics, environmental economics, and labour economics.

Simple answer

If your teacher wants the main branches , the safest answer is:

  1. Microeconomics.
  2. Macroeconomics.

If they want the expanded branches , then economics can have many branches, often more than 10, depending on how the subject is grouped.

Common branches

Here are some widely mentioned branches:

  • Microeconomics.
  • Macroeconomics.
  • International economics.
  • Public finance.
  • Development economics.
  • Health economics.
  • Environmental economics.
  • Labour economics.
  • Monetary economics.
  • Behavioural economics.

Best way to phrase it

You can say:

Economics is usually divided into two main branches, microeconomics and macroeconomics, but it also includes several specialized branches.

Quick note

So the answer to “how many branches are there in economics?” is: there is no single official number. For exams, 2 main branches is often the expected answer; for a broader academic view, there are many more.
