What does population pyramid show?

Age, gender, growth

The correct answer is Option (4) → Age, gender, growth

Option 4: Age, gender, growth - This option is the most accurate. A population pyramid explicitly shows age groups on the vertical axis and the gender distribution (male and female) on the horizontal axis. The overall shape of the pyramid directly indicates the past growth trends of the population (e.g., a wide base indicates high past birth rates and potential for future growth, while a narrow base suggests declining birth rates)

Thus, it visually shows the distribution of population by age and gender and helps to understand the population growth trends over time.

Other Options: 

• Option 1: Age, birth rate, growth - While a population pyramid shows age and can be used to interpret growth rate, it doesn't show the birth rate as a distinct axis or component.

• Option 2: Birth rate, gender, life expectancy - Similar to Option 1, it doesn't show current birth rate or life expectancy as explicit elements. It does show gender.

• Option 3: Life expectancy, Birthrate, Age - Again, life expectancy and current birth rate are not directly shown. Age is shown.
