The world population doubled twice between 1800 and 2020 due to advancements in medicine, agriculture, and technology. The first doubling occurred between 1800 and 1927, and the second doubling happened between 1927 and 1974. This rapid population growth has led to various challenges such as resource scarcity, environmental degradation, and social inequality.
Only during the current century.
