On November 15, the world population officially surpassed 8 billion people, according to United Nations estimates. The milestone was reached just 12 years after the world marked 7 billion people, and it is projected that global population will hit 9 billion people by 2037
So what are the key demographic trends driving population growth? Where is population growing fastest? Where is it declining? And what do the age structures of populations around the world tell us about the future of our planet? To answer these questions, we are joined by John Wilmoth, head of the Population Division at the United Nations Department of Economic and Social affairs.
We kick off with a brief history of population growth and with a discussion of the so-called demographic transition, which is the long process in which populations steadily live longer and have few children.

The world population has officially surpassed 8 billion people, according to estimates from the United Nations. This milestone was reached just 12 years after the world marked 7 billion people, and it is projected that global population will hit 9 billion people by 2037. What are the key demographic trends driving population growth? Where is population growing fastest? Where is it declining? These questions can be answered by understanding the process of the demographic transition, which is the long process in which populations steadily live longer and have fewer children.
What is the Demographic Transition?
The demographic transition is driven by the reduction of the death rate and the increase of the average lifespan. This process has been taking place all over the world, and is the result of a reduction in the number of deaths due to the prevention and treatment of infectious diseases. This is particularly evident in countries such as North America, where the process of the demographic transition was largely complete by the 1930s.
The reduction in the death rate has resulted in a period of rapid population growth due to an excess of births over deaths. This growth is expected to continue for a few more decades, until the fertility rate begins to decrease. At that point, the population will begin to stabilize and eventually start to decline.
The reduction in the death rate and the increase in the average lifespan are positive trends that should be celebrated. However, it is important to note that these trends are not evenly distributed across all countries. Wealthier countries have had access to better health care and treatments, leading to a greater reduction in the death rate and an increase in lifespan. Poorer countries, on the other hand, have not had the same access to resources, leading to greater disparities in population growth.
The process of the demographic transition is a positive trend that has enabled populations to live longer and have fewer children. This has resulted in a period of rapid population growth that is expected to continue for a few more decades. It is important to remember, however, that this trend is not evenly distributed across all countries, and that greater access to resources is needed in order to ensure that all countries can benefit from the demographic transition.
Population Growth is Slowing
Population growth is slowing, and this is due to a number of factors. The most significant of these is the process of the demographic transition, which is the shift from high birth and death rates to lower birth and death rates as a result of improved health care, education, and access to resources. This process has been occurring for centuries, but has accelerated in recent decades due to advances in modern medicine and technology. As a result, the global population has grown from less than a billion people in the 18th century to more than 8 billion people today.
The growth rate of the human population has been steadily declining since the 1960s, when it reached a peak of 2% per year. Today, the growth rate is below 1% per year, and our projections indicate that this trend will continue. This is due to a combination of decreasing death rates and increasing base populations, which together result in roughly 80 million people being added to the population every year. This figure has remained relatively constant for several decades.
The growth rate is expected to continue to decline, and the next billion people added to the population are expected to take 15 years instead of 12. By the end of the century, the human population is projected to reach a plateau of around 10.4 billion people, and then begin to decline. This is already occurring in countries such as China, which has a fertility rate below two point one births per woman over a lifetime.
Population growth is slowing, but this does not mean that the world is on the brink of a population crisis. On the contrary, the slowing of population growth is a positive trend that is helping to ensure the health and well-being of the world’s population. It is important to remember, however, that this trend is not evenly distributed across all countries, and that greater access to resources is needed in order to ensure that all countries can benefit from the demographic transition.
Education reduces poverty and fertility
One of the most important resources that can help ensure a healthy population is education. Education is a powerful tool for reducing poverty and fertility. Studies have shown that countries with higher levels of education tend to have lower fertility rates. This is because education helps to empower individuals and communities, giving them the knowledge and skills to make informed decisions about their health and well-being. Education also helps to reduce poverty by providing individuals and communities with the resources to make better decisions about their economic future.
In addition to reducing poverty and fertility, education also helps to reduce inequality and increase economic opportunities. Education provides individuals with the skills and knowledge necessary to participate in the global economy. It also helps to reduce gender inequality, as educated women are more likely to participate in the workforce and have greater economic opportunities.
Education is also an important tool for reducing population growth. By providing individuals with the knowledge and skills to make informed decisions about their health and well-being, education helps to reduce fertility rates and slow population growth. Education also helps to reduce poverty, which can lead to a more stable population.

As the world continues to face population growth challenges, it is important to remember the power of education in reducing poverty and fertility.
Finally, changing cultural norms can also play a role in the demographic transition. As cultures become more accepting of smaller family sizes, individuals are more likely to limit their fertility. This helps to reduce population growth and can lead to a more diverse population.
Universal social protection needed
One of the main challenges of the demographic transition is the shift in the age distribution of the population. As populations age, there are fewer people in the workforce, meaning those in the workforce must support those who are unable to support themselves. This means that there is an increased burden of dependency on the working-age population, as they must support both the younger and older generations.
Furthermore, the nature of consumption changes with age. Older people tend to consume more than children, particularly in terms of healthcare. This is a major fiscal challenge, as the cost of healthcare increases with age and is often quite high in countries with generous healthcare systems.
In order to address the challenges of the demographic transition, it is important to put in place policies that support the population as it exists today and in the future. One such policy is universal social protection, which ensures that nobody falls below a minimum level of existence. This includes old-age pensions, which are not yet common in all parts of the world. This safety net is especially important for older people, as it can be difficult for them to work as they age.
Overall, the demographic transition is an important process that is shaping the world’s population. By understanding the factors that drive the transition, we can better understand the challenges and opportunities that come with an increasingly diverse population. By implementing policies such as universal social protection, we can ensure that everyone is supported and that nobody falls below a minimum level of existence.
