Figures are from the World Gold Council, whose data adds up to precisely the same figures quarterly for global supply and demand. LBMA is for the London Bullion Market Association, which is often the global benchmark used for gold prices from data collected in its twice-daily auction process. Prices are given in U.S. dollars and per ounce of the commodity. Supply and demand are given in tonnes, a metric unit equal to 1,000 kilograms.
