What are the components of macroeconomics?

Macroeconomics primarily consists of several key components: national income, which measures the total economic output; inflation, which examines changes in price levels; unemployment rates, assessing the labor market's health; and economic growth, focusing on the increase in a country's output over time. Additionally, macroeconomics analyzes fiscal policy, involving government spending and taxation, and monetary policy, which pertains to the regulation of money supply and interest rates by central banks. These components collectively help to understand and manage the economy's overall performance.
