Which of the following can not be drawn from the Population Pyramid of a country?

The correct answer Total population size.

Mistake Points

• We cannot infer the size of the population from the Population Pyramid. We can only find out its characteristics. Hence option 4 is the correct answer.

Key Points

The population pyramid:

• It is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the
  world), which forms the shape of a pyramid when the population is growing.
• It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species.
• It mentions percentage-wise distribution within major age groups.
• Dependency ratio:- It is an age-population ratio of those typically not in the labor force (less than 15, and more than 65) and those typically in the labor force (15-65). 
• The shape of the population pyramid indicates the birth rate and death rate. So, we can find whether the population is growing/stable or reducing.  
• The population pyramid explicitly provides the percentages of males and females in all age groups. 
• We cannot infer the size of the population. We can only find out its characteristics.
