In the darkest blue you see the pyramid that represents the structure of the world population in 1950. Two factors are responsible for the pyramid shape in 1950: An increasing number of births broadened the base layer of the population pyramid and a continuously high risk of death throughout life is evident by the pyramid narrowing towards the top.

Age Structure, Population Growth, and Economic Development. The age structure of a population is an important factor in population dynamics. Age structure is the proportion of a population at different age ranges. Age structure allows better prediction of population growth, plus the ability to associate this growth with the level of economic development in the region.

A population pyramid, or age structure graph, is a simple graph that conveys the complex social narrative of a population through its shape. Demographers use these simple graphs to evaluate the extent of development for a given population - usually an individual nation - and to make predictions about the types of services that population ...

These are the question that this entry focuses on. The global median age has increased from 21.5 years in 1970 to over 30 years in 2019. The global population breakdown by age shows that a quarter (26%) are younger than 14 years, 8% are older than 65, while half of the world population is the working age bracket between 25 and 65.

These, in turn, influence the shape of the population pyramid. For an example, let's look at China's pyramid from 2008 that is shown here. Where the graph shrinks in for the age cohorts around 50, this shows the slowing of population growth during the Great Chinese famine. After the famine, we see population started increasing again.

ADVERTISEMENTS: Each population is a separate entity showing several characteristics such as spacing, size, density, natality, mortality, age structure, growth, fluctuations and cycle. 1. Spacing: The pattern of spacing of organisms is an important feature of every population. Spacing may be uniform, random or clumped. Uniform spacing is shown by invertebrate populations; random pacing occurs

Population: Age Structure Introduction One of the tools that demographers use to understand population is the age structure diagram (it is sometimes called a population pyramid, but it is not always pyramidal in shape).

Population pyramid - wikipedia

The population pyramid is one of the most popular tools for visualising population age structure. However, it is difficult to discern from the diagram the relative of effects different demographic components on the size of age-specific populations, making it hard to understand exactly how a population's age structure is formed.

The age group 10 years old declined rapidly. The mean age of the population in 1982 was 27.1 years; the median age was 22.8 years. 4.9% of the population were 65 years old. The magnitudes in 1982 were similar to 1953, but the shape is entirely different. The 1990 age pyramid shows a similarity to the 1982 population for the age groups 8 years old.
