What do demography and epidemiology have in common?
Epidemiology and demography, even at a cursory glance, have much in common. Both are quantitative disciplines deeply concerned with the human condition. Both explore the dynamics and characteristics of geographically-defined populations, and, as such, take a global view of human activities and events, including health.
How are demographic and epidemiological transition related?
This epidemiological transition is the result of a series of interrelated factors: Demographic changes: the reduction in childhood mortality leads to a decrease in fertility rates. As a consequence, a higher percentage of the population reaches the adult age and develops adult-related diseases.
What does demographics mean in epidemiology?
Basically demography studies the change of the population in terms of its size, influenced by fertility, mortality and migration. The correspondence to that in the field of health is not epidemiology but “public health”, which looks at the change in health status at the population level.
Who is the father of demography in public health?
John Graunt, (born April 24, 1620, London—died April 18, 1674, London), English statistician, generally considered to be the founder of the science of demography, the statistical study of human populations.
Who is father of demography?
John Graunt
What is concept of demography?
“Demography is the study of the size, territorial distribution, and. composition of population, changes therein, and the components of. such changes, which may be identified as natality, mortality, territorial movement (migration), and social mobility (change of status).”
What are the two types of demography?
Demography – the study of human populations Births, deaths and migration are the ‘big three’ of demography, jointly producing population stability or change.
What is the main focus of demography?
Demography is the statistical study of human populations. Demography examines the size, structure, and movements of populations over space and time. It uses methods from history, economics, anthropology, sociology, and other fields.
What are the 3 purposes of demography?
Demographers seek to understand population dynamics by investigating three main demographic processes: birth, migration, and aging (including death). All three of these processes contribute to changes in populations, including how people inhabit the earth, form nations and societies, and develop culture.
What is the contribution of demography?
Around 50% of the demographic contribution is explained by the increase in the average productivity per worker (productivity component), which arises from the change in the population’s age structure and the rise in households’ saving rate.
What is demography and why is it important?
WHAT IS DEMOGRAPHY AND WHY IS IT IMPORTANT? Demography is the branch of social sciences concerned with the study of human populations, their structure and change (through births, deaths, and migration), and their relationship with the natural environment and with social and economic change.
How does demography affect society?
Demographic change can influence the underlying growth rate of the economy, structural productivity growth, living standards, savings rates, consumption, and investment; it can influence the long-run unemployment rate and equilibrium interest rate, housing market trends, and the demand for financial assets.
What is the importance of demography to public health?
The health and health care needs of a population cannot be measured or met without knowledge of its size and characteristics. Demography is concerned with this and with understanding population dynamics – how populations change in response to the interplay between fertility, mortality and migration.
What is the relationship of demography to globalization?
Globalisation has also its own demographic model: swift increase of individuals mobility from the rural area and from the farming lifestyle to the urban area which is closer linked to global trends with respect to food, markets, fashion and leisure.
What are the effects of globalization?
At the same time, global economic growth and industrial productivity are both the driving force and the major consequences of globalization. They also have big environmental consequences as they contribute to the depletion of natural resources, deforestation and the destruction of ecosystems and loss of biodiversity.
What is the importance of demographic transition?
Using the Demographic Transition Model, demographers can better understand a country’s current population growth based on its placement within one of five stages and then pass on that data to be used for addressing economic and social policies within a country and across nations.
What are the factors of global demography?
Demographic factors, including gender, age, race, and ethnicity, provide a general indication of those groups in the general population that are at the highest risk of suicide.
What is the current state of global demography?
The global population, which stood at just over 2 billion in 950, is 6.5 billion today. The world is currently gaining new inhabitants at a rate of 76 million people a year (representing the difference, in 2005, between 34 million births and 58 million deaths).
