How many sevants are there in the world?

As of my last knowledge update in October 2021, there are an estimated 1 in 1,000 individuals who are considered savants, which can translate to approximately 7 to 10 million people worldwide, depending on the total global population. However, this figure can vary based on different definitions of savant syndrome and the methods used for identification. It's important to note that the prevalence of savant syndrome is not precisely documented, and numbers may have changed since then.
