A variety of measures of national income and output are used in economics to estimate total economic activity in a country or region, including gross domestic product (GDP), Gross national income (GNI), net national income (NNI), and adjusted national income (NNI adjusted for natural resource depletion – also called as NNI at factor cost). All are specially concerned with counting the total amount of goods and services produced within the economy and by various sectors. The boundary is usually defined by geography or citizenship, and it is also defined as the total income of the nation and also restrict the goods and services that are counted. For instance, some measures count only goods & services that are exchanged for money, excluding bartered goods, while other measures may attempt to include bartered goods by imputing monetary values to them.

👉 Measures of national income and output in the context of Factor income
Factor income (also called primary income and earned income) is the flow of income that is derived from the factors of production, i.e., the general inputs required to produce goods and services. Factor income on the use of land is called rent, income generated from labor is called wages, and income generated from capital is divided between profit for equity owner and interest for creditor. The total amount of factor income received by the residents of a country is referred to as the national income, while factor income and current transfers together are referred to as disposable income.
In contemporary national accounting, Indirect taxes minus subsidies are treated like factor income despite not meeting the definition. In earlier system like the 1953 SNAdefined to concept of GDP : the sum of all factor income called GDP at factor cost, and the sum of all expenditure called GDP at market price. (GDP at market price = GDP at factor cost + Indirect taxes minus subsidies). Factor cost measured have being abandoned by the SNA.

Measures of national income and output in the context of Final good
A final good or consumer good is a final product ready for sale that is used by the consumer to satisfy current wants or needs, unlike an intermediate good, which is used to produce other goods. A microwave oven or a bicycle is a final good.
When used in measures of national income and output, the term "final goods" includes only new goods. For example, gross domestic product (GDP) excludes items counted in an earlier year to prevent double counting based on resale of items. In that context, the economic definition of goods also includes what are commonly known as services.
Measures of national income and output in the context of Economic growth
In economics, economic growth is an increase in the quantity and quality of the economic goods and services that a society produces. It can be measured as the increase in the inflation-adjusted output of an economy in a given year or over a period of time.
The rate of growth is typically calculated as real gross domestic product (GDP) growth rate, real GDP per capita growth rate or GNI per capita growth. The "rate" of economic growth refers to the geometric annual rate of growth in GDP or GDP per capita between the first and the last year over a period of time. This growth rate represents the trend in the average level of GDP over the period, and ignores any fluctuations in the GDP around this trend. Growth is usually calculated in "real" value, which is inflation-adjusted, to eliminate the distorting effect of inflation on the prices of goods produced. GDP per capita is the GDP of the entire country divided by the number of people in the country. Measurement of economic growth uses national income accounting.
Measures of national income and output in the context of Balance of payments
In international economics, the balance of payments (also known as balance of international payments and abbreviated BOP or BoP) of a country is the difference between all money flowing into the country in a particular period of time (e.g., a quarter or a year) and the outflow of money to the rest of the world. In other words, it is economic transactions between countries during a period of time. These financial transactions are made by individuals, firms and government bodies to compare receipts and payments arising out of trade of goods and services.
The balance of payments consists of three primary components: the current account, the financial account, and the capital account. The current account reflects a country's net income, while the financial account reflects the net change in ownership of national assets. The capital account reflects a part that has little effect on the total, and represents the sum of unilateral capital account transfers, and the acquisitions and sales of non-financial and non-produced assets.
Measures of national income and output in the context of Monetarism
Monetarism is a school of thought in monetary economics that emphasizes the role of policy-makers in controlling the amount of money in circulation. It gained prominence in the 1970s, but was mostly abandoned as a direct guidance to monetary policy during the following decade because of the rise of inflation targeting through movements of the official interest rate.
The monetarist theory states that variations in the money supply have major influences on national output in the short run and on price levels over longer periods. Monetarists assert that the objectives of monetary policy are best met by targeting the growth rate of the money supply rather than by engaging in discretionary monetary policy. Monetarism is commonly associated with neoliberalism.
Measures of national income and output in the context of Investment (macroeconomics)
In macroeconomics, investment "consists of the additions to the nation's capital stock of buildings, equipment, software, and inventories during a year" or, alternatively, investment spending — "spending on productive physical capital such as machinery and construction of buildings, and on changes to inventories — as part of total spending" on goods and services per year. "accounting"The types of investment include residential investment in housing that will provide a flow of housing services over an extended time, non-residential fixed investment in things such as new machinery or factories, human capital investment in workforce education, and inventory investment (the accumulation, intentional or unintentional, of goods inventories)In measures of national income and output, "gross investment" (represented by the variable I ) is a component of gross domestic product (GDP), given in the formula GDP = C + I + G + NX, where C is consumption, G is government spending, and NX is net exports, given by the difference between the exports and imports, X − M. Thus investment is everything that remains of total expenditure after consumption, government spending, and net exports are subtracted (i.e. I = GDP − C − G − NX ).
"Net investment" deducts depreciation from gross investment. Net fixed investment is the value of the net increase in the capital stock per year.
