Gross Domestic Product QoQ

Gross Domestic Product, or GDP, is the market value of finished goods and services made in the United States. It equals value added, or output less inputs used in production. It covers the whole economy and leaves out used inputs, imports, and earnings from abroad.

In the National Income and Product Accounts it equals Gross Domestic Income in concept but differs in practice from separate sources. The Bureau of Economic Analysis builds it from agency and business sources with no single survey panel. The Bureau gives no target or trading guide and sets no growth bands.

Each release covers the three calendar months of the quarter. The advance estimate comes about one month after the end on incomplete data plus stated premises. Three vintages follow under embargo at 8:30 Eastern time in the morning.

Advance comes near the end of the first month. Second comes near the end of the second month, and Third near the end of the third month. Advance holds GDP tables only, Second adds early profits, and Third adds revised profits plus industry and state data. Every vintage also shows cash value output, final sales, price gauges, and income use.

Each quarter revises across vintages as fuller data arrive. Annual updates revise past results, and full rebuilds follow after long gaps. Each release reads the headline by parts that rise or fall, partly set against each other. A core gauge strips trade, stocks, and government to show private demand.

Four spending groups drive the total, and shares below show rough size that shifts each quarter. Each release shows which group lifted the headline and which held it back.

• Personal consumption expenditures (PCE), 68%: household spending on goods and services, from cars and food to housing and health care.
• Gross private domestic investment, 18%: fixed outlays on structures, equipment, software, research, and homes, plus swings in unsold stock.
• Net exports of goods and services, -3%: exports minus imports, with imports set negative since spending mixes home and foreign goods.
• Government consumption and investment, 17%: federal defense and nondefense plus state and local outlays on services and structures.

In one past two-quarter spell, real output fell 1.6% then 0.6% at annual rates, yet no broad slump was called. Lower retail stocks, housing, and federal plus state spending pulled down the total, while exports and consumer spending partly set against the fall. Imports, a subtraction in the total, rose. The case shows that two down quarters alone do not prove a slump when inner demand stays firm.

• Final spending: sum household spending, business outlays, government outlays, and exports, then take off imports since data mix home and foreign goods.
• Seasonal fix: use set adjusted inputs where ready, else test with Census tools and build the total from set parts at annual rates.
• Fisher strip: cut inflation with a Fisher index from two nearby quarters, the middle path of old and new price weights.

• Chained levels: set real levels from the index times reference value over 100 and parts do not add and shares cannot give growth.
• Annual pace: stretch a quarter move to an annual pace. A rise from 100 to 105 or 5% in one quarter reads as 21.6%.
