As of that time, determining the absolute youngest person in the world is difficult since babies are born every second. The youngest person in the world is constantly changing as new births occur.
The youngest person in the world would typically be a newborn baby who was just born, but there is no specific individual who holds this title for an extended period as babies are born continuously around the globe. The birth rate is a constantly changing statistic, and new babies are born every moment in different parts of the world.
For the most up-to-date information on world demographics or birth rates, you would need to refer to current sources such as the World Bank, the United Nations, or other reputable organizations that track global population data in real-time.
