Wood Mackenzie forecasts annual real GDP (US$) and GDP growth to the year 2035 for more than 180 economies. Forecasts are updated on a quarterly basis. This report contains an excel download of our complete Global GDP dataset. Short-term GDP is forecast using a combination of lead indicators and an assessment of key economic variables over the current business cycle, including monetary and fiscal policy drivers. The long-term growth potential of an economy is underpinned by three structural drivers: (i) demographics; (ii) investment/ growth in capital stock; and (iii) productivity growth. We forecast long-term GDP by assessing these structural supply-side drivers using a set of proprietary GDP models developed by Wood Mackenzie.
