GDP Glossary: Every Acronym and Term Explained

The Bureau of Economic Analysis's first GDP release for a quarter, published approximately 30 days after the quarter ends. Based on approximately 75 percent of source data; subject to revision in the second and third estimates. Often the most market-moving release because it is the first look.

A quarterly growth rate expressed as if that pace were sustained for a full year. BEA convention. If the economy grows 0.125 percent in one quarter, the annualised rate is approximately 0.5 percent. Used in US GDP reporting; most other countries report year-on-year (YoY).

Bureau of Economic Analysis, a bureau of the U.S. Department of Commerce. The primary publisher of US national income and product accounts (NIPA), including quarterly GDP estimates. URL: bea.gov.

BEA's current methodology for calculating real GDP, adopted in 1996. Uses average prices from two adjacent years to compute growth, rather than fixed base-year prices. Prevents distortions from rapidly falling prices in sectors like computing. Today BEA expresses real GDP in 'chained 2017 dollars.'

Consumer Price Index. A measure of price changes for a fixed basket of consumer goods and services, published by the Bureau of Labor Statistics (BLS). Differs from the GDP deflator: the CPI covers only consumer spending and uses a fixed basket; the deflator covers all GDP and updates its composition each period.

Calculating GDP by summing all final spending: C + I + G + (X - M). One of three equivalent approaches to GDP measurement. The most widely reported.

Federal Reserve Economic Data. The St. Louis Fed's open-access database of over 800,000 economic time series including all BEA GDP series. Available at fred.stlouisfed.org. The best interface for downloading and charting historical US GDP data.

The price index used to convert nominal GDP to real GDP. Calculated as (Nominal GDP / Real GDP) x 100. Covers the entire GDP basket (not just consumers). A deflator of 105 means prices are 5 percent higher than the base year.

Gross Domestic Product. The total market value of all final goods and services produced within a country's borders during a specific period, usually a quarter or year. The most widely used single measure of economic size.

Gross National Income. GDP plus net primary income received from abroad (returns on foreign investments minus payments to foreign investors). The World Bank uses GNI for country income classification. Conceptually equivalent to GNP but defined more precisely in the System of National Accounts.

Gross National Product. The total value of goods and services produced by a country's citizens and businesses, regardless of where production occurs. Largely superseded by GNI in international statistics. The US reported GNP as its headline measure until December 1991.

Human Development Index. Published annually by the United Nations Development Programme (UNDP) since 1990. Combines life expectancy at birth, education (mean and expected years of schooling), and GNI per capita into a single score from 0 to 1. Norway consistently tops the HDI.

International Comparison Program. The World Bank's statistical programme that collects price data to compute purchasing power parities (PPP) across countries. Conducted approximately every six years; the most recent comprehensive round was 2017.

International Monetary Fund. Publishes the World Economic Outlook (WEO) twice yearly, providing GDP data and projections for all member countries. Also publishes the Global Financial Stability Report and Fiscal Monitor. URL: imf.org.

Calculating GDP by summing all incomes generated in production: wages, profits, rents, and taxes on production minus subsidies. One of three equivalent approaches; produces the same GDP total as the expenditure and production approaches.

Goods used as inputs in producing other goods, not sold to final consumers. Excluded from GDP to avoid double-counting. The steel in a car, the flour in bread, the chips in a smartphone are all intermediate goods. Only the final product counts.

National Bureau of Economic Research. A non-partisan US research organisation. Its Business Cycle Dating Committee officially dates the beginnings and ends of US recessions. Uses a broader set of indicators than the popular 'two-quarter rule.' URL: nber.org.

Exports minus imports (X - M). The component of GDP that adjusts for trade. Negative for the US (the US imports more than it exports) at approximately -3 percent of GDP. Positive for export-surplus economies like Germany and China.

National Income and Product Accounts. The BEA's framework of accounting tables that measure US economic activity. Key tables include 1.1.1 (percent change in real GDP), 1.1.5 (GDP and components at current prices), and 2.1 (personal income and outlays). Published quarterly.

GDP measured at current market prices with no inflation adjustment. Grows even if actual output is unchanged, if prices rise. Used for currency-denominated comparisons (trade, debt) but not for growth comparisons over time.

Purchasing Power Parity. An adjustment to GDP that accounts for different price levels across countries. A dollar buys more in India than in the US; PPP-adjusted GDP reflects this. China leads the world on PPP-adjusted GDP at approximately $43.5 trillion (IMF WEO April 2026).

Calculating GDP by summing the value added at each stage of production across all industries. Value added equals the value of output minus the cost of intermediate inputs. One of three equivalent GDP measurement approaches.

GDP adjusted for inflation using the GDP deflator. Expressed in 'chained 2017 dollars' by BEA. Shows whether actual output increased, not just prices. The growth figures reported in the news are always real GDP.

Formally defined by NBER as 'a significant decline in economic activity spread across the economy, lasting more than a few months.' The popular 'two consecutive quarters of negative GDP growth' rule is a heuristic, not the official definition. NBER did not declare a recession in 2022 despite two negative GDP quarters.

The BEA's third and most complete GDP release for a quarter, published approximately 90 days after the quarter ends. Uses the most comprehensive data including Treasury, IRS, and Census Bureau sources. Still subject to annual benchmark revisions.

The long-run sustainable real growth rate of an economy. US trend growth has been approximately 2 percent per year since 2000, down from approximately 3.5 percent in 1950-2000. Set by productivity growth and labour-force growth.

The value of output produced at each stage of production minus the cost of intermediate inputs. Summing value added across all industries produces GDP under the production approach. Prevents double-counting of intermediate goods.

World Economic Outlook. The IMF's semi-annual projections report, published in April and October. Contains GDP, inflation, unemployment, and fiscal data for all IMF member countries, with 5-year projections. April 2026 WEO is the source for 2026 GDP rankings cited throughout this site.
