Ans. Population distribution refers to the pattern of where people live within a particular area. It is the spread of people across a particular region, country, or the world.

The population distribution can be clustered, dispersed, or in between.
2. What is population density?
Ans. Population density is the measurement of the number of people living per unit area or volume. It is calculated by dividing the population of an area by its size. It indicates how crowded or sparse a particular area is. The population density can be high, moderate, or low depending on the number of people living in a particular area and the amount of available space.
3. What is population growth?
Ans. Population growth refers to the increase in the number of people living in a particular area over a specific period.
