a) population ecology - the study of how biotic and abiotic factors influence the density, distribution, size, and age structure of populations b) demography - study of the vital stats of a population and how they change over time c) cohort - group of individuals of the same age 3. four factors Population Age Structure 5-9 All countries populations can be classified into one of four major age structure types based on their progression through the demographic transition, which is the decades-long shift that many countries have followed from high mortality and fertility rates to longer life expectancies and later, to smaller family size. The age-specific life table is based on the fates of individuals in a real cohort, a group of individuals born in the same time interval, whereas a time-specific life table is based on the fate of individuals in an imaginary cohort derived from the age structure of a stable population with overlapping generations at a point in time. Age structure data allow the rate of growth (or decline) to be associated with a populations level of economic development. Many factors may affect the intensity of a COVID-19 outbreak in a given country, including underlying health conditions in the population, the effectiveness of government response, and the availability of health care resources. This is recognised in the UK, where NHS resources are allocated on the basis of age-weighted capitation. In the absence of a conscious effort to control the size of families, the larger the fraction of the population who are in the fertile age range the more rapid will be the population growth, and this will influence the average age of the population structure towards the younger end of the spectrum. The opposing factor to fertility rate is mortality rate, which is equal to the typical amount of deaths per the same amount of the population in the year. After the famine, we see population started increasing again. The fertility rate of a population refers to the average amount of children that women have throughout their lifetime, adjusted to births per certain amount of the population in the year. For an example, lets look at Chinas pyramid from 2008 that is shown here. The growth has been accompanied by profound changes in the age structure of the population. Factors affecting changes in the age structure of the Ghanaian population, 1960 - 1970: a preliminary analysis. Age structure. In other words, it is the number of births for every 1000 people in the country. The overwhelming influence on health service needs is the size and age structure of the population. It is the average number of the children born in a country compared to the rest of the population. Aging of population (also known as demographic aging, and population aging) is a summary term for shifts in the age distribution (i.e., age structure) of a population toward older ages. PIP: An important characteristic of the Ghanaian population is its high potential for growth. Factors affecting the population The Birth Rate. These, in turn, influence the shape of the population pyramid. Where the graph shrinks in for the age cohorts around 50, this shows the slowing of population growth during the Great Chinese famine. Engmann EV. A populations growth rate is strongly influenced by the proportions of individuals of particular ages. With knowledge of this age structure, population growth can be more accurately predicted. Five factors are considered including environmental pressures, the initial age structure of the population, migration, epidemics and other natural disasters, and fertility.
