Answer 2

Reason for a Bulge in Pyramid

Explanation:

• The shape of the pyramid exposes the age sex interrelation of a particular population. A broad-based pyramid indicates that folks within the younger age categories structure a comparatively large proportion of the population, and a narrow or pointed top indicates that older people conjure a comparatively small proportion of the population.
• Within the older age groups of the many populations, the quantity of females is way greater than the quantity of males; this can be reflected within the shape of the pyramid, specified the bars on the proper side of the central axis (the female side) are longer than those on the left (male) side.
• The median age of the population would be the age bracket (bar) represented by the purpose on the vertical axis that equally divides the realm within the pyramid (equal areas represented by the bar).  
• Fertility and mortality of the population also are reflected within the shape of the population pyramid. The broader base of the pyramid shows the high birth and mortality in younger sections.
• Irregularities within the profile of the population pyramid convey information about changes within the population or aberrations.
• A bulge or an indentation within the profile of the population pyramid may indicate unusually high fertility or mortality or changes within the population due to immigration or emigration.
