The population growth in developed countries is usually zero or negative the pyramid has a narrow base resulting from the low birth rate and a broad bulge in the all the age groups which reflects the increase in life expectancy resulting from improvement in medical knowledge people live longer on an average and therefore has an aging populationExplain How can you gain info on this statistic from the pyramid? An increasing proportion of the population is in the 65 age group Morocco Stage 4 Contractive Convex sides Very low birth rate Low death rate Longer life expectancy Higher dependency ratio
High mortality in young age groups significantly lowers the life expectancy at birth But if a person survives his/her childhood of high mortality, he/she may live much longer For 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 personHigh death rates pyramid is narrow along the sides, especially the middle & top !Population Pyramids INFORMATION POSSIBLE FROM A POPULATION PYRAMID 4 Birthrate from the base of the pyramid 5 Life expectancy can be inferred 6 Can infer economic status (for example, agriculture or industrialized type of nation)
Population pyramid a graphic method of illustrating the age and sex structure of a population Describe the population pyramid for Niger The 10 population pyramid for Niger is expansive, and it is in the perfect shape of a pyramid It clearly shows that Niger has a high birth rate and low life expectancy because there are many newborns andView Population_Pyramids from BIOLOGY 223 at Gaston College Statistic Meaning Is high or low better? Niger's Population Pyramid Niger's population is mostly people aged 15 and under The majority of the population is under 5 years old, which shows how low the life expectancy half of the population dies before they reach 30 The population is however split quite evenly between female and male
Explain How can you gain info on this statistic from the pyramid? POPULATION PYRAMIDS (1) 1 Describe the information that you would conclude from a triangular shaped, rectangular shaped, and inverted triangular shaped pyramid Triangular shaped The triangular shaped pyramid tends to have a large proportion of population in the early ages This also shows Egypt has a low life expectancy that steeper 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

The shape of the population pyramid gradually evolves over time based on fertility, mortality, and international migration trends Some distinctive types of population pyramids are A youthful distribution has a broad base and narrow peak and is characterized by a high proportion of children and low proportion of the elderly This population distribution results from high fertility, high mortality, low life expectancy,"Expansive" pyramid or Expanding population pyramid A population pyramid that is very wide at the younger ages, characteristic of countries with a high birth rate and perhaps low life expectancy The population is said to be fastgrowing, and the size of each birth cohort increases each year "Constrictive" pyramid or Declining population A population pyramid that isThere are 3 main patterns of population pyramid First a pyramid shape – this has a high birth rate, high death rate and low life expectancy 5 Second is a bell shape This has a lower birth and death rate and higher life expectancy
5 demographic factors that make the population pyramids for different countries vary?Population Pyramids in LICs Population pyramids in lowincome countries typically have a wide base and a narrow top The population pyramid below shows the population structure for Kenya, an LIC The narrow top indicates there are few elderly people, illustrating shorting lifeexpectancyConical shape, wide base, narrow top

By Ava Torjani A recent study demonstrated a significant improvement in life expectancy among the leastexpected countries, including Niger, Nicaragua, Ethiopia, Gambia, Nepal, and Peru These are lowincome countries with relatively lowThis indicates that there is a high birth rate and low life expectation This indicates a population that is growing quickly The final type of pyramid is a "constrictive" pyramid These pyramids are narrower at the bottom A country or region with this type of pyramid has a population that is generally older These areas typically have longer life expectancy rates and a low death rate, as well as a low Note the disparity between male and female elderly in the United States Women tend to outlive men in every population group In the US, life expectancy for men is 773 but for women, it is 1
Stage 1 population pyramids Wide base due to extremely high birth rate ;The World Population Pyramid displays age, sex and population data for 100 years We have chosen the years between for our Pyramid to show a balance of historical and future projections Increases or decreases in death rates or in number of children born can affect these results This Pyramid is a useful tool for the visual display of 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 ranges

Death rate is high in all age groups, so life expectancy is low;Death rates are low Life expectancy is high Birth rates are high Birth rates are low 1High birth rates BASE of pyramid is
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 Population Pyramids are used to analyze growth, or decline of the fertility rate, mortality, and migration in cities These can be put into three different shapes, the Christmas tree, the box, and the cup The Christmas Tree This show that the growth rates are slow There is a high birth rate There is a short life expectancy The population pyramid varies with countries, along with the variation of fertility, mortality, lifeexpectancy and agesex structure This can be visualized from the following table The percentage of population under the age group of 15 is highest in developing countries (328%) compared to developed countries (1)
Stage I High birth, High death, Low growth Stage II High birth, Declining death, Increasing growth Stage III High birth, Low death, High growth Stage IV Declining birth, Low death, Declining growth Stage V Low birth, Low death, Low growthVery narrow apex and the shortest of all the pyramidsVertical extent reflects low life expectancy As the type of pyramid is generally identified on the basis of share of population in lower and middle age groups, therefore this stage pyramid is expanding pyramid In case of Niger even at present (17) 50 per cent population of the country is below 15 years and in Angola
Kenyaagnew kenyaagnew Biology Middle School answered What conclusion can you draw from the population pyramid?Usually pyramids are drawn with the % of male population on the left and % of female population on the right It gives us information about birth and death rates as well as life expectancy AStraight or near vertical sides depicts a low death rate 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 Rapidly tapering top or concave slope suggests
Life expectancy at birth fell to a level as low as ten years for females and seven for males in 1933 and plateaued around 25 for females and 15 for males in the period 1941–44 According to The Oxford companion to World War II , "Over 7 million inhabitants of Ukraine, more than onesixth of the prewar population, were killed during theIf this statistic is Expansive pyramid Overall shape is an upright pyramid, with a broad base Describes a population with High fertility rate High mortality rate Low life expectancy High fertility rate High mortality rate Low life expectancy Each age group is smaller than the age group before it Indicates fast growth
Death rates are low Life expectancy is high Birth Get the answers you need, now!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 pyramid
