5. What are the factors that affect a country's age-sex pyramid?
Answers
Answer:
- A population pyramid, also called an "age-gender-pyramid", is a
graphical illustration that shows the distribution of various age groups in
a population (typically that of a country or region of the world), which forms the
shape of a pyramid when the population is growing. Males are conventionally shown
on the left and females on the right, and they may be measured by raw number or
as a percentage of the total population. This tool can be used to visualize the age of
a particular population. It is also used in ecology to determine the overall age
distribution of a population; an indication of the reproductive capabilities and
likelihood of the continuation of a species.
A population pyramid is a way to visualize two variables: age and sex. They are
used by demographers, who study populations. A population pyramid is a graph
that shows the distribution of ages across a population divided down the center
between male and female members of the population. The graphic starts from
youngest at the bottom to oldest at the top. It is called a population pyramid
because when a population is growing (there are more babies being born than there
are people dying), the graphic forms the shape of a triangle. A population pyramid
can be used to compare differences between male and female populations of an
area. They also show the number of dependents (children and, sometimes, elderly
people) and general structure of the population at any given moment.
Population pyramids are useful for studying the future of a region as well as
examining historical and current population trends. If part of the population has
been affected by sudden changes, such as casualties from armed conflict, high
female mortality in childbirth, or the migration of young workers out of poorer
regions, the graph will offer a way to visualize how the future population will be
affected. They can also help direct government and private industry distribution of
services for regions based on population needs.
Population pyramids help show how populations are composed and how they are
changing. Here is a population pyramid from the United States in August 2016
showing various age groups: baby boomers, generation X, generation Y, and
generation Z. Typically, there are three trends in population pyramids: expansive,
constrictive, and stationary. These illustrate the trajectory of a regional population,
which may be growing, shrinking, or staying the same.
