First Quarto Document for Stat 210

Practice

January 22nd (H.D.S 1.3)

America’s GDP rose at a 4.4% annual pace in the third quarter. * Key GPD components and their approximate contributions to the 4.4% growth : Personal Consumption Expenditures (C) — The largest component, typically around 68% of GDP. Consumer spending rose at about 3.5% annualized, contributing roughly 2.3–2.4 percentage points to growth. This was led by services (e.g., healthcare, recreation, and other services) and goods (e.g., recreational items and nondurables like prescription drugs and food). Gross Private Domestic Investment (I) — Includes business equipment, structures, intellectual property, and residential construction. It turned positive in the updated estimate, adding a small net contribution (around 0.1–0.4 percentage points overall), with strength in equipment and intellectual property offsetting some weakness in residential and nonresidential structures. Government Consumption Expenditures and Gross Investment (G) — Federal, state, and local spending. It increased (around 2.2% annualized), contributing about 0.4 percentage points to growth, driven by both defense and non-defense outlays. Net Exports (X - M) — Exports minus imports.A major positive driver, adding around 1.5–1.6 percentage points. Exports surged (up ~9–9.6% annualized, especially in goods like capital equipment and services), while imports fell (~4–5% annualized), boosting the net figure. These contributions sum to the headline 4.4% growth. Consumer spending remains the economy’s backbone, but trade improvements and rebounds in other areas fueled the acceleration from Q2’s 3.8%.
