GDP and gross national product (GNP) answer related but different questions. GDP counts final goods and services produced within a country’s borders. GNP starts with GDP, then adjusts for primary income flowing between residents and the rest of the world. That makes GNP a measure tied to the labor and property supplied by residents, wherever they are located. Neither measure assigns every product or dollar of output to a company’s home country.
GDP follows the place of production
GDP records the market value of final goods and services produced inside a country during a given period. A factory’s location matters: production at a plant within the country contributes to its GDP, regardless of whether the facility is locally or foreign owned. The measure is designed to describe activity within an economic territory. Bureau of Economic Analysis
GDP is a broad measure of output, not a tally of all sales or of residents’ income. It is also reported in different forms: nominal GDP uses current prices, while real GDP adjusts for inflation to make comparisons over time more meaningful. Bureau of Economic Analysis
GNP adjusts for cross-border income
The basic relationship is GNP = GDP + income receipts from the rest of the world − income payments to the rest of the world. GNP therefore starts with domestic production and adjusts for primary income associated with labor and property supplied by residents, even when they are located abroad. The BEA defines GNP in terms of goods and services produced by labor and property supplied by U.S. residents, wherever located. Bureau of Economic Analysis
Receipts can include compensation paid to residents by foreigners, interest and dividends received from abroad, and reinvested earnings on residents’ direct investment abroad. Payments run in the other direction: primary income paid to nonresidents for labor or property they supply. These are income flows, not the value of goods crossing a border.

Residency is not nationality or ownership
The relevant distinction is residency, not citizenship or the nationality of a firm’s owners. A foreign-owned factory inside a country contributes its production to that country’s GDP. Its entire output does not automatically become part of the owners’ home-country GNP: local residents may supply labor and other factors, and their contribution is not transformed into foreign residents’ income simply because the company is foreign-owned. Bureau of Economic Analysis
Likewise, a resident-owned business operating abroad does not mean that all production at its foreign site counts toward the residents’ home-country GNP. GNP adjusts for the primary income connected to labor and property supplied by residents. The production location and the residence of the income earner both matter; ownership alone does not settle the accounting. Bureau of Economic Analysis
A simple hypothetical calculation
Suppose a country has GDP of 1,000, residents receive 50 in primary income from abroad, and residents pay 30 in primary income to nonresidents. Its GNP is 1,000 + 50 − 30 = 1,020. These numbers are hypothetical. The 50 and 30 represent income flows, such as compensation, interest, dividends, or qualifying reinvested earnings—not exports and imports. Bureau of Economic Analysis
Trade in goods and services is a separate concept. An exported product is counted in GDP where it is produced; an imported product is produced elsewhere. Buying or selling across a border does not itself determine who receives primary income. GDP helps assess production within borders, while GNP adds a view of primary income tied to residents’ labor and property. Bureau of Economic Analysis Bureau of Economic Analysis
