Q. Consider the following statements
Which of the statements given above is/are correct?
Explanation
Statement 1 is correct: A population pyramid is a graphical representation of the age and sex composition of a specific population. It consists of two histograms, one for each gender (by convention, men on the left and women on the right) where the numbers are shown horizontally and the ages vertically.
Statement 2 is incorrect: It depends on interactions between fertility, mortality and migrations. The shape of the pyramid and its variations over the years depend, above all, on the variations in fertility.
