Chapter 4: Problem 9

How does infant or child mortality correlate to population growth rate, and why is this relationship generally seen?

Short Answer

Expert verified

Infant/child mortality and population growth rate are negatively correlated, meaning as infant/child mortality decreases, population growth rate increases, and vice versa. This relationship is due to factors such as improved healthcare, fertility rates, socio-economic development, and government policies. As infant/child mortality decreases, healthcare access improves, fertility rates decline, socio-economic conditions develop, and effective government policies are implemented, all contributing to a slower population growth rate.

Step by step solution

Define the terms

To analyze the correlation, we should first understand what infant/child mortality and population growth rate mean. - Infant/child mortality: It is the death of infants or children under a specific age per a given number of live births, usually expressed as a rate per 1,000 live births. - Population growth rate: It is the percentage change in the size of a population over a given period, typically calculated on a yearly basis.

Identify the correlation

Generally, it is observed that there is a negative correlation between infant/child mortality and population growth rate. In other words, as infant/child mortality decreases, the population growth rate increases, and vice versa. In order to visualize this relationship, we can look at data from different countries and see how these two variables are related.

Explain the reasons behind the relationship

There are several factors that can help explain the negative correlation between infant/child mortality and population growth rate: 1. Improved healthcare: A decrease in infant/child mortality often results from improvements in healthcare services and access to medical facilities. This, in turn, contributes to an increase in the overall health of the population, reducing the death rate and leading to an increase in population growth rate. 2. Fertility rates: High infant/child mortality rates tend to be associated with higher fertility rates, as parents may have more children to compensate for the loss of children due to high mortality rates. As infant/child mortality decreases, fertility rates often decrease as well, resulting in a slower population growth rate. 3. Socio-economic development: Decreases in infant/child mortality rates often accompany socio-economic development, including improvements in education, employment, and living conditions. These factors can contribute to increased life expectancy and a decrease in the birth rate, leading to a slower population growth rate. 4. Government policies: Government policies, such as family planning or child welfare programs, can also play a role in reducing infant/child mortality rates and promoting sustainable population growth. When these policies are well-implemented, they can lead to a decrease in infant/child mortality and a stable population growth rate. In conclusion, infant/child mortality is negatively correlated to population growth rate, as a decrease in infant/child mortality is often accompanied by increased healthcare access, socio-economic development, and effective government policies which lead to lower fertility rates and a slower population growth rate.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Infant Mortality and Population Growth

Infant mortality is a critical indicator of a nation's health and development. It represents the number of infants, typically under one year of age, who die per 1,000 live births. Understanding this concept is key to analyzing its impact on population growth. High infant mortality rates suggest health challenges and inadequate healthcare services, which can lead to higher birth rates as parents might have more children, anticipating that not all may survive infancy. This in turn can result in temporary increases in population growth rates.

On the flip side, as infant mortality rates decline due to improved healthcare and better living conditions, parents often choose to have fewer children. This reduction in the birth rate generally leads to a lower population growth rate over time. Thus, reducing infant mortality is not just a moral imperative, but also a critical lever in shaping demographic trends.

Child Mortality's Influence on Population Dynamics

Child mortality, which encompasses the death of children under the age of five, is closely related to infant mortality but covers a wider age range, offering a broader perspective on the health issues affecting young children. High child mortality rates can also increase the fertility rates, as families tend to have more children to counterbalance the uncertainty of child survival.

However, with advances in medical sciences, vaccination programs, and improved nutrition, child mortality rates have decreased in many parts of the world. This public health success has often led to a decline in population growth rates, as smaller families become the norm when child survival is assured. Countries that have successfully reduced child mortality usually experience transitions towards more sustainable population growth patterns.

Socio-Economic Development and Demographic Changes

Socio-economic development encompasses a broad range of improvements in the quality of life, including education, income levels, employment opportunities, and living standards. As a society advances socioeconomically, there are profound effects on its demographic structure, including on population growth rates.

Improved literacy, especially among women, often leads to better family planning and lower birth rates. Enhanced economic conditions mean fewer economic incentives to have large families. Moreover, development is typically accompanied by urbanization, where children are less likely to contribute economically to the household, further discouraging large family sizes. All of these factors contribute to a decline in both infant and child mortality rates, and eventually, to a moderating population growth rate.

Fertility Rates and Their Demographic Ramifications

Fertility rates, or the average number of children a woman is expected to have during her lifetime, are a pivotal determinant of population growth. High fertility rates are often found in regions where both infant and child mortality rates are high, prompting families to have more children to ensure that enough survive to adulthood.

Conversely, as countries develop and the survival of children becomes more certain, fertility rates tend to drop. This demographic transition entails a shift from high to lower birth rates and has a cascading effect on slowing population growth. In regions with low fertility rates, populations may even shrink, raising different socio-economic challenges such as an aging workforce and the need for immigration to maintain population size. Understanding fertility rates provides insight into the current and future state of population demographics.
