Since 2010, the WLA has been collecting and compiling lottery sales data from WLA members around the world on a quarterly basis. Currently around 35 lotteries, representing approximately 60% of global lottery sales by volume, provide these figures to the WLA. The data is aggregated, analyzed, and published on this website as the WLA Quarterly Lottery Sales Indicator to provide lotteries, suppliers, and the general public with a snapshot of shorter-term global and regional sales trends.
