Who is the oldest person alive?

The title of the oldest living person in the world is a constantly changing one, as it is unfortunately inevitable that each person who holds it will eventually pass away. As of my knowledge cutoff date of September 2021, the oldest living person on record was Kane Tanaka, a Japanese woman born in 1903 who was recognized by Guinness World Records as the world’s oldest living person. However, it is important to note that this information is subject to change and that there may be other people who have since surpassed her age. Additionally, there are likely many people who live to be very old but whose ages go unverified, meaning that they are not officially recognized as the oldest living person.
