National Income

National Income is income for a country. It is the money value of the flow of output of goods and services produced within an economy over a period of time.About national income I think we could know the living standard of the country.It can reflect the economy of the country.So let's seewhat can affect national income in our economy.

First of all I think a big part of national income is real GDP .So to make more national income one way is to increase real GDP ,and to increase GDP as we know we need to increase Aggregate demand So as we all know AD= C+I+G+(X-M) So we can increase real GDP by increasing each of them.

Measuring the level and rate of growth of national income (Y) is important to economists when they are considering:
The rate of economic growth
Changes over time to the average living standards of the population
Changes over time to the distribution of income between different groups within the population (i.e. measuring the scale of income and wealth inequalities within society)

National Output = National Expenditure (Aggregate Demand) = National Income
So if we could increase Aggregate demand then the national income will also increase and our economy will growth .The standard of living will be better.
