IOC research shows that 85 per cent of all permanent venues used at the Olympic Games from Athens 1896 to PyeongChang 2018 – and 92 per cent of permanent venues used in the 21st century – remain in use, long after the various Games editions finished, bringing social and economic benefits to local communities.
Other key findings of the report include:
The percentage of new permanent venues (i.e. those built for the Games) and existing permanent venues (i.e. those which already existed when the host city/territory was selected to host the Games) that are still in use is similar (87 and 83 per cent respectively);
87 per cent of the complex venues, such as stadiums, Olympic Villages, swimming pools, velodromes, ski jumping hills, sliding centres and ice hockey stadiums, are still in use;
The proportion of temporary venues has evolved over time. These account for 16 (early 20th century), 9 (mid-20th century), 7 (late 20th century), and 14 per cent (21st century) of venues respectively.
