Define Population Pyramid
a type of graph that shows the age and sex structure of the country; the distribution of age, sex, and population of different countries is known as population structure and is represented on a population pyramid

What do Concave Sides on Population Pyramids imply
can indicate low life expectancy and very high death rate. this is because few individuals survive to move from one cohort to another
41
What does a Wide Base on Population Pyramids imply
indicates a relatively high birth rate but low life expectancy. as a result, the pyramid narrows rapidly because a large number of those born are not surviving to reach an older age group
42
What do Perpendicular Sides on Population Pyramids imply
tells us that majority of those born, survive to an old age. this indicates a middle- or high-income country
