Supplementary notes

Figures for Beijing 2022 were taken from this (page 58) published on the official Olympics website. While the data was not presented in the same way as figures for 2026, ��ƽ�� found that they could be ordered into the same categories based on Table 9 (page 50) from this .��

The source’s terminology, which is explained on page 78 of its 'Sustainability, Impact and Legacy Report 2024', can be summarized with the following:

Games planning and delivery: activities corresponding to organization and management of the Games. This included transport for athletes’ families, setting up temporary venues, logistics, and the sale of merchandise.

Construction of permanent infrastructure: relates to the building of permanent venues (both sporting and non-sporting), as well as transport infrastructure built specifically for the Games.

Associated activities: activities that are indirectly connected with the planning and management of the Games, such as the travel activities and accommodation used by spectators.��
