Human Population What type of growth does this graph display? Exponential Which Continent has the greatest population of Humans? Asia

***For your notes-if it is in RED write it down Age Distribution: A population pyramid that displays trends and patterns of growth. There are 3 types of Population Pyramids:

Expansive population pyramid: Shows larger numbers or percentages of the population in the younger age groups, usually with each age group smaller in size or proportion than the one born before it. These types of pyramids are usually found in populations with very large fertility rates and lower than average life expectancies. The age-sex distributions of Latin American and many Third World countries would probably display expansive population pyramids

2. Constrictive population pyramid Displays a population where the population numbers are reduced at the lower ages The age-sex distributions of the United States fall into this type of pyramid. In the United States, the population is growing at a rate of about 1.7 percent annually. This growth rate is reflected in the more square-like structure of the pyramid. Note the lump in the pyramid between the ages of about 35 to 50. This large segment of the population is the post-World War II baby boom. As this population ages and climbs up the pyramid, there will be a much greater demand for medical and other geriatric services. .

3. Stationary or near-stationary: population pyramids display somewhat equal numbers or percentages for almost all age groups. Of course, smaller figures are still to be expected at the oldest age groups. The age-sex distributions of some European countries, especially Scandinavian ones, will tend to fall into this category. Germany is experiencing a period of negative growth (-0.1%). As negative growth in a country continues, the population is reduced. A population can shrink due to a low birth rate and a stable death rate. Increased emigration may also contribute to a declining population
