Trade in goods and services is defined as the transactions in goods and services between residents and non-residents. It is measured in million USD at 2015 constant prices and PPPs, as percentage of GDP for net trade, and also in annual growth for exports and imports. All OECD countries compile their data according to the 2008 System of National Accounts (SNA).

Trade in goods and services forecast is defined as the projected value of change in ownership of material resources and services between one economy and another. Projections are based on an assessment of the economic climate in individual countries and the world economy, using a combination of model-based analyses and expert judgement. The indicator comprises net trade, imports and exports and export market growth. Net trade is the value of exports minus the value of imports; imports and exports are the value of goods and services imported or exported from other economies; export market growth measures the demand for a country’s exports constructed as a weighted average of import growth in all export destinations using export shares as weights. This indicator is measured in USD for net trade, annual growth rate for exports and imports and USD, 2015 prices for exports, imports and export market growth.

Trade in goods includes all goods which add to, or subtract from, the stock of material resources of a country by entering its economic territory (imports) or leaving it (exports). This indicator is measured in million USD. Goods are physical, produced items over which ownership rights can be established and whose economic ownership can be passed from one institutional unit to another by engaging in transactions. Goods being transported through a country or temporarily admitted or withdrawn (except for goods for inward or outward processing) are not included. All OECD countries compile their data according to the 2008 System of National Accounts (SNA).

Trade in services records the value of services exchanged between residents and non-residents of an economy, including services provided through foreign affiliates established abroad. This indicator is measured in million USD and percentage of GDP for exports, imports and net trade. Services include transport (both freight and passengers), travel, communications services (postal, telephone, satellite, etc.), construction services, insurance and financial services, computer and information services, royalties and license fees, other business services (merchanting, operational leasing, technical and professional services, etc.), cultural and recreational services, and government services not included in the list above. Trade in services drives the exchange of ideas, know-how and technology, although it is often restricted by barriers such as domestic regulations. All OECD countries compile their data according to the 2008 System of National Accounts (SNA).

The current account balance of payments is a record of a country's international transactions with the rest of the world. The current account includes all the transactions (other than those in financial items) that involve economic values and occur between resident and non-resident entities. Also covered are offsets to current economic values provided or acquired without a quid pro quo. This indicator is measured in million USD and percentage of GDP.

The current account balance forecast measures the projected value of a country's net international transactions with the rest of the world. The current account includes all the transactions (other than those in financial items) that involve economic values and occur between resident and non-resident entities. Projections are based on an assessment of the economic climate in individual countries and the world economy, using a combination of model-based analyses and expert judgement. This indicator is measured in USD and as a percentage of GDP.

This indicator shows the contribution to exports by different sized enterprises. Business size is measured by the number of employees and exports are measured in trade value in millions of USD. SMEs employ fewer than 250 people, with further subdivision into micro enterprises (fewer than 10 employees), small enterprises (10 to 49 employees), medium-sized enterprises (50 to 249 employees). Large enterprises employ 250 or more people.

This indicator shows the contribution to imports by different sized enterprises. Business size is measured by the number of employees and imports are measured in trade value in millions of USD. SMEs employ fewer than 250 people, with further subdivision into micro enterprises (fewer than 10 employees), small enterprises (10 to 49 employees), medium-sized enterprises (50 to 249 employees). Large enterprises employ 250 or more people.

Terms of trade are defined as the ratio between the index of export prices and the index of import prices. If the export prices increase more than the import prices, a country has a positive terms of trade, as for the same amount of exports, it can purchase more imports.

Domestic value added in gross exports is an estimation of value added, by an economy, in producing goods and services for export, simply defined as the difference between gross output at basic prices and intermediate consumption at purchasers' prices. The measure is a percentage share of value. Value added can be decomposed into the following components: compensation of employees; gross operating surplus; mixed income; and other taxes on production less subsidies on production. It can also be derived as the difference between GDP (at market prices) and taxes on products less subsidies on products.

Import content of exports is defined as the share of imported inputs in the overall exports of a country, and reflects the extent to which a country is a user of foreign inputs. The measure is also often referred to as the ‘foreign value-added share of gross exports’ and is defined as the foreign value-added in gross exports divided by total gross exports, in percentage. It is considered as a reliable measure of international ‘backward linkages’ in analyses of global value chains.
