Verified step by step guidance1
Understand the question is asking for the approximate fraction of the world's population living in urban areas (cities).
Recall that urbanization refers to the increasing number of people living in cities compared to rural areas.
Consider recent global demographic data which shows that more than half of the world's population now lives in urban areas.
Recognize that the commonly accepted estimate for the current urban population fraction is around 55%, meaning just over half of people live in cities.
Compare the given options (25%, 55%, 75%, 95%) and identify that 'About 55%' best matches the current global urban population estimate.
