Stationary pyramid Represents a population in which age and sex distribution remain constant over time ;Low birth rates and higher life expectancy contribute to the transformation of Europe's population pyramid shape The most significant change is the transition towards a much older population structure, resulting in a decrease in the proportion of the working age while the number of the retired population increasesKiribati has a low life expectancy rate of just 63 for women and 57 for men with many health problems caused by the consumption of semiraw seafood, bacterial contamination of food, and little storage Just 10 years ago, up to 7% of the population was treated each year for food poisoning in a hospital
In the low life expectancy variant, growth is lower than in the principal population, with a projected population of 721 million Overall, over the period from mid16 to mid41, the life expectancy variants have a small effect on the original projection and much less of an impact than the fertility variants§ HOW to read a population pyramid?

Equal birth and death rates ; 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, and high population growthA 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 Places with an ageing population and a very low birth rate would have a structure that looks like an upsidedown

The Population pyramids are the true graphical representation of a population's age and sex Countries with better living conditions, geriatric care, and medical facilities have a high expectancy of life Also, The number of people in the older age group is usually low and thus has a narrow topStart studying Population Pyramids Learn vocabulary, terms, and more with flashcards, games, and other study toolsPopulation 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
A narrow base means a smaller proportion of young people, suggesting a low birth rate A wide middle, tall pyramid means an ageing population, suggesting that there is aThe India 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 ofA pyramid with a wide base and steep sides indicates a country with high birth rates and low life expectancy For example, similar to many developing countries, Pakistan has a high birth rate and a low life expectancy Its pyramid (see below) has a wide base because of a high birth rate However, the pyramid slants sharply as the age groups progress because of the low life expectancy

Despite these improvements, life expectancy is generally shorter in lowincome than highincome countries due to discrepancies in resources, income, and access to healthcare BBC's illustration of population pyramids organized by a country's socioeconomic statusFrom this graph, one can calculate life expectancy The life expectancy formula is taken by first calculating the probability of a population's survival at every year in the life table Wealthier people and women tend to have longer life expectancies Let's say that a life table reflects a population of 1 million people beginning in 1940The base of the population pyramid shows birth rates are falling and that the death rate has stabilised at a low level The increasing proportion of elderly people (compared to the population pyramid for Kenya, an LIC), show death rates are falling and life expectancy is increasing
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 person survives his/her childhood, he/she may live much longer than 50 yearsA low life expectancy can be defined as a belowaverage age a person might reach on average when he or she is born for every respective date Especially in poor developing countries, life expectancy is quite low compared to rich industrialized countriesStraight 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
