> Gross Domestic Income (GDI) is the total income that all sectors of an economy generate, including wages, profits, and taxes.

## What Is Gross Domestic Income (GDI)?

Gross domestic income (GDI) is a measure of a nation's economic activity based on money earned for all goods and services produced during a specific period.

In theory, GDI should be identical to gross domestic product ([GDP](https://www.investopedia.com/terms/g/gdp.asp)), a more commonly used measure of a country's economic activity. However, different data sources used in each calculation lead to somewhat different results.

Generally, GDP tends to be the more reliable metric, as it is based on fresher and more expansive information.

### Key Takeaways

*   Gross domestic income (GDI) and gross domestic product (GDP) are two slightly different measures of a nation's economic activity.
*   GDI counts what all participants in the economy make, such as wages and profits.
*   GDP counts the value of what the economy produces, like goods, services, and technology.
*   One of the core concepts of macroeconomics is that income equals spending, which means that GDI should be the same as GDP in an economy at equilibrium.

## Understanding Gross Domestic Income (GDI)

GDI is the total income that all sectors of an economy generate, including wages, profits, and taxes.

It is a lesser-known statistic than GDP, which is used by the [Federal Reserve Bank](https://www.investopedia.com/terms/f/federalreservebank.asp) to measure total economic activity in the United States.

One of the core concepts in the field of [macroeconomics](https://www.investopedia.com/terms/m/macroeconomics.asp) is that income equals spending. This means that the money spent on purchases should theoretically equal money generated from production.

## Formula and Calculation of Gross Domestic Income

Note the differences in formula for GDI compared to the formula for GDP:  

*   **GDI** = Wages + Profits + Interest Income + Rental Income + Taxes - Production/Import Subsidies + Statistical Adjustments
*   **GDP** = Consumption + Investment + Government Purchases + Exports - Imports

Wages encompass the total compensation to employees for services rendered. Profits, also called "net operating surplus," are the [surpluses](https://www.investopedia.com/terms/s/surplus.asp) of incorporated and unincorporated businesses. Statistical adjustments may include corporate income tax, dividends, and undistributed profits.

The most significant component of GDI is wages and salaries. Historically, roughly 50% of all national income goes to workers. In the first quarter of 2024, U.S. GDI clocked in at roughly $27.6 trillion, with $14.7 trillion taking the form of employee compensation.

> Another large component of GDI is the net operating surplus from private enterprises. In the first quarter of 2024, about $6.5 trillion of the $27.6 trillion in GDI was attributed to that category.

## GDI vs. GDP

According to the Bureau of Economic Analysis (BEA) of the U.S. Department of Commerce, GDI and GDP are conceptually equivalent in terms of national economic accounting, with minor differences attributed to statistical discrepancies. The market value of goods and services consumed often differs from the amount of income earned to produce them due to [sampling errors](https://www.investopedia.com/terms/s/samplingerror.asp), coverage differences, and timing differences.

But while the difference between GDI and GDP is usually minimal, they can sometimes vary up to a full percentage point for some quarters. The gap also varies over different periods of time.

GDI differs from GDP, which values production by the amount of output that is purchased, in that it measures total economic activity based on the income paid to generate that output. In other words, GDI aims to measure what the economy takes in (like wages, profits, and taxes) while GDP seeks to measure what the economy produces (goods, services, technology).

> **Tip**

> GDI calculates the income that was paid to generate GDP. So, an economy at equilibrium will see GDI equal to GDP.

Some economists have argued that GDI might be a more accurate gauge of the economy. The reason is that more advanced estimates of GDI are closer to the final estimates of both calculations. Research from Federal Reserve economist Jeremy Nalewalk showed that early estimates of GDI captured the [Great Recession of 2007-2009](https://www.investopedia.com/terms/g/great-recession.asp) better than GDP, suggesting that policymakers would have been better prepared if GDI was the main indicator used.

Over time, according to the BEA, "GDI and GDP provide a similar overall picture of economic activity." For annual data, the correlation between GDI and GDP is 0.97, according to BEA calculations.

## Gross Domestic Income Analytics

GDI figures have various analytical uses:

*   One important metric is the ratio of wages and salaries to GDI. The BEA compares this ratio with corporate profits as a share of GDI to see where the constituents, mainly workers and company owners, stand relative to each other with respect to their share of GDI. A rule of thumb states that workers' share of GDI should be higher when unemployment is low.
*   Employee compensation share of GDI is also compared with the [inflation](https://www.investopedia.com/terms/i/inflation.asp) trendline. Economists generally anticipate that higher employee compensation share will correlate with an upward trend in inflation.

## What Is the Difference Between GDI and GNI?

Gross domestic income (GDI) and gross national income (GNI) are two closely related concepts. The former counts generated domestically, hence the name; the latter counts all income generated by a nation's residents, including from income sources abroad.

## Which Country Has Highest GNI?

The United States has the highest GNI. Per latest data available from the World Bank, the country recorded a GNI of $25.59 trillion in 2022. China, which came in second, recorded a GNI of $18.13 trillion.

## What Is GNI Per Capita in U.S.?

According to most recent data published by the World Bank, GNI per capita in the U.S. was $76,770 in 2022. The country ranked eighth across the world.

## The Bottom Line

Gross domestic income (GDI) measures a country's economic activity based on all income generated domestically in a certain window.

It's a less commonly used metric compared to gross domestic product (GDP), which measures a country's output. GDI and GDP are typically very close in value, with slight variations attributable to differences in the data from which they draw.
