Detailed explanation-2: -And while every population pyramid is unique, most can be categorized into three prototypical shapes: expansive (young and growing), constrictive (elderly and shrinking), and stationary (little or no population growth). Let’s take a deeper dive into the trends these three shapes reveal about a population and its needs.

Detailed explanation-3: -Migration affects population growth rate. There are two types of migration: Immigration is the movement of individuals into a population from other areas. This increases the population size and growth rate.
