What is the relationship between demography and public health?

What is the relationship between demography and public health?

Demography is the scientific study of human populations. It is important to understand the structure of a population in order to plan health and public health interventions; population structures can be represented as age pyramids. Population growth or decline depends upon fertility, mortality and migration.

What is the relevance of the discipline 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.

How does demography affect health?

Demographic influence on health care and long-term care demand – Different methods? Changes in age composition of the population will affect needs and demand for health and social care. Care needs are not evenly divided among age groups in the population. Cost per capita tends to rise sharply with age.

What is demography in health care?

Demography is the study of the profile and habits of populations, e.g. their age, gender, ethnicity, fertility, mortality and migration patterns [2].

What is demographic transition in public health?

Demographic Transition is a gradual process in which a society moves from high birth rate and death rate to low birth rate and death rate. It deals with population change occurring from the past to the change that may occur in future.

What are the 5 components of demography?

Therefore, demography is the scientific study of human population primarily with respect to size, structure, distribution and change (development). In short, demography is the scientific study of population. Population change results from interaction of demographic components, viz, birth, death and migration.

What is the purpose of demography?

Demography is useful for governments and private businesses as a means of analyzing and predicting social, cultural, and economic trends related to population.

Why are demographics important in planning health care?

Demographers have been crucial in the first stage, since population changes are a key component of changing health needs. Demographic analysis looks at behavioural changes in the population and how these might change a population’s structure (age) and composition (gender, race, and so on) in the medium and long term.

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 4 stages of demographic transition?

The model has four stages: pre-industrial, urbanizing/industrializing, mature industrial, and post-industrial. In the pre-industrial stage, crude birth rates and crude death rates remain close to each other keeping the population relatively level.

What are the three stages of demographic transition?

Stages of the Demographic Transition

• Stage 1—High birth and death rates lead to slow population growth.
• Stage 2—The death rate falls but the birth rate remains high, leading to faster population growth.
• Stage 3—The birth rate starts to fall, so population growth starts to slow.

What is the most important use of demography in public health?

The health and healthcare 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 are types of demography?

The field of demography can be divided into two general areas, basic or academic demography and applied demography.
