Most of the worlds population resides in which climate zone

Most of the 'world's population' resides in the 'temperate climate zone' in the northern hemisphere.

Explanation:

68% of the total worlds land comes in the 'northern hemisphere'. Thus, this hemisphere naturally holds most of the world's population. The temperate climate zone in this hemisphere, which is characterized by the presence of equal seasons of winter and summer, is home to most of the world's population. It is because this climate is most favorable for humans to survive and carry out most activities.
