Population Pyramid 1 Wide base due to extremely high birth rate Sides curve in quickly due to High infant mortality (number of babies that die under a year of age per 1000 live births) High child mortality (number of children that die under 5 years of age per 1000 live births)Death rate high in all ages so life expectancy is low causing the narrow apex and short pyramidPopulation Pyramids features of LEDC male female The population is broken up into male and female and age ranges This makes it easy to make comparisons between genders The population between the yellow lines is the working population In a poorer country there will be a higher dependant population( > 50%)( young and old ) puttingA population pyramid that is very wide at the younger ages, characteristic of countries with a high birth rate and perhaps low life expectancy 6 The population is said to be fastgrowing, and the size of each birth cohort increases each year 8 A population pyramid that
High birth rates BASE of pyramid is Population Pyramids A population pyramid graphically illustrates the age and gender distribution of a given population The shape of the pyramid conveys details about life expectancy, birth, fertility, and mortality rates Additional data that can be extrapolated from a population pyramid include the effects of historical events, economicDeveloping nations are poorer (low GDP) and limited economic development Life Expectancy Low Literacy Rate Low Urban Population Low Medical Care and Technology Low Per Capita GDP Low Low birth
A population pyramid that is very triangular (eg Mozambique in 00) shows a population with a high number of young dependants and a low life expectancy A population pyramid that This also shows that the countries that fit in this triangular shaped pyramid tend to have low life expectancies since death rate is very high Rectangular shaped The rectangular shaped pyramid tends to have the same population size overtime MEDCs are examples of this shaped pyramid since population size is kept controlled"Constrictive" pyramid or Declining population A population pyramid that is narrowed at the bottom The population is generally older on average, as the country has long life expectancy, a low death rate, but also a low birth rate This may suggest that in future there may be a high dependency ratio due to reducing numbers at working ages
Population Pyramid Stages Population pyramid for Niger Description Niger is at an expansive stage, with concave sides for both male and female populations This means that this country has a high birth rate, a high death rate, and short life expectancy We can tell that there is high birth rate because the bars (population) near the rangesA population pyramid is a graphical representation of a country's population distribution by age and sex What is a developing nation?

A population pyramid that is very triangular (eg Mozambique in 00) shows a population with a high number of young dependants and a low life expectancy A population pyramid that has fairly straight sides (more like a barrel) shows a population with a falling birth rate and a rising life expectancy Over time, as a country develops, the shape changes from triangular to barrellike The wide base shows that they have a HIGH birth rate (44/1000) The height of the pyramid tell us that they have a low life expectancy (currently 68 years) In Uganda approx 48% of the population is between 0 14A population pyramid that has fairly straight sides (more like a barrel) shows a population with a falling birth rate and a rising life expectancy Rapidly tapering top or concave slope suggests high death rate and low life expectancy Over time, as a country develops, the shape changes from triangular to barrellike
Stable/Stationary Stable Pyramid This type of population distribution shows a rectangular or squarish shape, with almost the same number of people in all age groups There is a slight taper at the top, which is perfectly natural, due to more deaths occurring among the elderly Such countries have a high life expectancy, where more people live–Rectangle / chimney –Grandparents kids equaling out •Deaths equaling births •Average Age = late 30s, early 40s •Dependency ratio = 21High death rate because life expectancy is low ( 66 years for men and 77 for women ) Russia has a high death rate ( 134 deaths per 1000 per year) many to do with alcohol related deaths and HIV low birth rate contributing to a declining population
See Figure 5) Figure 5 Temporal Changes in Life Expectancy at Birth for Russians and Americans, by Gender, 1926–1994/95For example, in a population with a life expectancy at birth of 50, there may be few people dying at age 50 The life expectancy at birth may be low due to the high childhood mortality so that once a person survives his/her childhood, he/she may live much longer than 50 years
