As of my knowledge cutoff in September 2021, the exact number of people attempting to break Guinness World Records each year is not publicly available. However, it is known that thousands of people from around the world participate in Guinness World Record attempts annually.


Guinness World Records receives a large number of record applications and inquiries from individuals and groups who aim to set or break records. The organization provides guidelines, rules, and support to individuals and event organizers to facilitate record attempts.


Guinness World Records has a team of record managers and adjudicators who review and verify the attempts based on specific criteria. The number of records officially recognized and the number of individuals attempting records can vary each year, and it would require access to Guinness World Records' internal data to provide more specific figures.


It's worth noting that Guinness World Records covers a wide range of categories, from sports and entertainment to science, technology, and more. Therefore, the number of record attempts can vary across different fields of interest.
