What is a slow growth population pyramid?
Slow or Stable Growth Population Pyramid Only after the upper ages do you see a marked change in population. This type of population pyramid is mostly found in developed countries sometimes middle income countries. These countries have good health care, long life expectancies and stable governments.
What are the 3 types of population pyramids growth?
There are generally three types of population pyramids created from age-sex distributions– expansive, constrictive and stationary.
What type of population pyramid shows negative population growth?
A top-heavy pyramid suggests negative population growth that might be due to many factors, including high death rates, low birthrates and increased emigration. A bottom-heavy pyramid suggests high birthrates, falling or stable death rates and potential for rapid population growth.
What are the 4 types of population pyramids?
There are five stages of population pyramids: high fluctuating, early expanding, late expanding, low fluctuating, and natural decrease.
What does a decreasing population pyramid look like?
Constrictive population pyramids are used to describe populations that are elderly and shrinking. Constrictive pyramids can often look like beehives and typically have an inverted shape with the graph tapering in at the bottom.
What does negative growth look like on a graph?
So the graph of “negative exponential growth” is ALWAYS a line curving downward toward zero.
What does a declining population pyramid look like?

What does a negative population pyramid mean?
A decrease in birth rates and immigration rates while experiencing an increase in elderly people and emigration rates indicates the country is experiencing a negative growth rate. The population will almost be upside down when compared to a rapid growth pyramid.
How do low growth population graphs compare?
How do low-growth-rate population graphs compare? Low-growth-rate countries are straight. How long would it take to double Nigeria’s population? What does this pyramid shape imply about the size of the reproductive class of the population?
