10/29/19-pop pyramid

Today in class, we learned what a population pyramid is.  A population pyramid is a graph that shows the amount of population there is of each age.  It's also divided by gender and the age increases by 5 year increments.  Girls are always on the right and boys are always on the left.  Ages 0-14 are referred to as the pre-reproductive age.  Ages 15-44 are referred to as the reproductive age and ages 45 until death are referred to as the post-productive ages.  This is only for girls though, boys are not referred to any of these.  The shape that the lines make on a population pyramid show whether a country is growing quickly or slowly or decreasing quickly or slowly.  It can also determine which age group people should get jobs for.  For example, if the population is biggest is the 0-14 categories, you may consider getting a job working for a toy company.  Or if the population is the biggest in the 45+ categories, you may want to become a care giver because the need will be higher.
