GDP growth (annual %)
Latest reading is highest in China at 4.96% and lowest in Japan at 1.19%. Period average is 2.94%, with a cross-economy spread of 3.77 percentage points. This is a rate of change rather than a level, so compound growth and a growth index are not defined for it; the trend is reported in percentage points per year. Fitted trend is steepest upward in United States (+0.04 pp/yr, percentage points per year, R² 0.004) and weakest in China (-0.24 pp/yr, R² 0.195). Largest acceleration — last three years against the three before — is Japan at +528.5% percentage points. The largest covered value is 4.2× the smallest. 3 economies covered; latest observation year 2025.

Trend is the ordinary-least-squares fit of value on year, reported with its R² — how much of the movement
the straight line explains, in percentage points per year because this series is already a rate.
Momentum is the mean change of the last three years minus the mean of the three before it, in percentage points. Half-period shift
compares the second half of the window against the first. Volatility is the standard deviation of year-over-year change.
Outlier years exceed 2.5 standard deviations from that economy's own average change.
