Below, the rest of the discussion with CP on the Demographic Transition. Interesting to
see how the AI, on Think Deeper, alludes to the Western Centrism of the concept...

A recent pronouncement that contributed me to my interest in elucidating Baby Boomer
thoroughly:

Oh, and big surprise for me. Born in 1949 in Canada, I am not - strictly speaking - a
baby boomer.(1952-1965). That was a big part of my identity??!!
As of may 2025... Duration Boomers are
BABYBOOM USA: 1946-1964 61-79 years of age
BABYBOOM CANADA: 1952-1965 60-73 years of age

Post WWII Baby Boom; how was the Baby Boom different in Canada than in the US?
Great question! While both Canada and the U.S. experienced a Baby Boom after World War II, there were some key differences:
Timing: The Baby Boom in the U.S. is generally defined as occurring between 1946 and 1964, whereas in Canada, the boom lasted from 1952 to 1965. This means Canada’s peak birth years came slightly later than those in the U.S.
Birth Rates: Canada’s birthrate surged significantly, reaching its highest point in 1959, while the U.S. peaked in 1957. The Canadian boom was also more concentrated, with fewer births before 1952 compared to the U.S.
Economic Influence: The Canadian Baby Boom was largely driven by strong economic growth in the 1950s and early 1960s, which encouraged larger families and stay-at-home mothers. In contrast, the U.S. boom was more closely tied to post-war optimism and returning soldiers starting families.
Demographic Impact: The Baby Boom generation in Canada had a profound effect on education, employment, and housing, leading to overcrowded schools and a competitive job market for those born in the peak years. In the U.S., similar effects were seen, but the sheer size of the American population meant the impact was spread out more.
Social Policies: Canada’s Baby Boom was influenced by government policies that encouraged family growth, such as improved healthcare and social welfare programs. The U.S. had similar policies, but Canada’s approach was more centralized.
The Baby Boom shaped both countries in lasting ways, but Canada’s experience was distinct in its timing, economic drivers, and demographic effects. Want to dive deeper into any of these aspects? 😊
Was North America's demograpic transition considered completed when the Baby Boom began, or was there overlap between the two phenomena?
Great question! There was overlap between North America's demographic transition and the Baby Boom rather than a clear-cut completion before the boom began.
The demographic transition refers to the shift from high birth and death rates to lower birth and death rates as a country develops. In North America, this transition was well underway by the early 20th century, with declining mortality rates due to medical advancements and improved living conditions. However, birth rates had not yet stabilized at low levels when the Baby Boom began.
The Baby Boom (1946–1964 in the U.S., 1952–1965 in Canada) occurred during the later stages of the demographic transition. While death rates had already dropped significantly, birth rates temporarily spiked due to post-war optimism, economic prosperity, and social factors encouraging larger families. This surge in births was somewhat unexpected, as demographic transition models typically predict a steady decline in birth rates following industrialization.
(Think Deeper)Where does the notion of demographic transition come from; when did it first appear. Elaborate!
The notion of the demographic transition originated as scholars began to observe and classify the changing patterns of population growth that accompanied modernization. Early in the 20th century, demographers noticed that many countries moved from a regime of both high birth and death rates to one where both were low—a pattern that later became known as the demographic transition.
The groundwork was laid by early analyses such as Warren Thompson’s work in 1929. Thompson proposed a classification that grouped countries according to their observed patterns of fertility and mortality—highlighting how these rates changed as nations developed. This early classification pointed out that demographic patterns were not fixed, but evolved with socioeconomic changes.
Building on these observations, French demographer Adolphe Landry in 1934 was one of the first to explicitly use the concept of a “demographic transition” in his work La Révolution Démographique. Landry’s analysis focused on how improvements in public health, reductions in mortality, and growing economic development set the stage for a later decline in birth rates. His work underscored that the transition was not merely a statistical quirk but a reflection of deep societal changes.
The concept was further formalized in the 1940s when Frank W. Notestein expanded on these ideas. In his influential 1945 article—often cited as a seminal work in demography—Notestein described the process by which societies shift from high mortality and high fertility to low levels of both, linking these changes to broader economic and social development. Although Notestein himself did not originally label this process as a “transition,” his work established the framework that modern demographers would later adopt and refine.
Thus, while early observations by Thompson and explicit terminology introduced by Landry in the 1920s and 1930s set the stage, it was the work of Notestein in the mid-20th century that solidified the demographic transition model as a central theory in population studies. This model has since become a crucial tool for understanding how industrialization, improvements in health care, economic prosperity, and other societal changes drive shifts in population dynamics over time .
Beyond its origins, the theory has evolved to inform discussions about contemporary population challenges—such as aging populations and rapid urbanization—in both developed and developing nations. Would you be interested in exploring how these evolving dynamics influence current policy-making or how similar transitions are being observed (or not) in different parts of the world?
So, rather than marking the end of the demographic transition, the Baby Boom was a temporary deviation from the expected trend. After the boom ended, birth rates resumed their decline, completing the transition to a low-birth, low-death rate equilibrium.

Is demographic transition a notion that applies to Asia?
Yes, the notion of demographic transition definitely applies to Asia, though its patterns and timing can differ considerably from those first observed in Western societies.
The demographic transition theory describes a shift from high birth and death rates to lower rates as societies modernize. Initially, this concept was based on European and North American experiences, where improvements in health, sanitation, and economic development led to a gradual decline in mortality, followed by a decline in fertility. However, as these core dynamics—declining mortality motivating later reductions in fertility due to improved child survival, shifts in economic incentives, and expanded educational opportunities—are universal, the theory is a useful framework for understanding demographic changes in Asia as well .
In Asia, the overall process unfolds in stages similar to the classical model, yet with regional nuances. For instance, countries like Japan, South Korea, and Singapore have seen very rapid transitions into low fertility and aging populations, creating challenges such as workforce shortages and pressures on social services. In contrast, many countries in South and Southeast Asia are—or have been—in the midst of significant demographic shifts. They experienced initial improvements in healthcare and reductions in mortality rates, but the subsequent drop in fertility has often been more gradual or uneven, shaped by cultural traditions, economic disparities, and policy interventions. In this context, the demographic transition is not only observed but also deeply influential in shaping economic development and social policy across the region .
Moreover, the diversity within Asia means that while the framework of the demographic transition is applicable, each country’s path is unique. For instance, China's rapid transition was notably affected by state policies such as the one-child policy, which accelerated shifts in age structure and fertility behaviors. Similarly, nations like India and Indonesia display transitional characteristics that require tailored policy responses addressing both youth unemployment and eventual aging trends. This adaptability of the demographic transition theory makes it an essential tool for understanding the multifaceted demographic changes occurring across Asia today.

Let's take South Korea as an example...
South Korea offers a striking example of a rapid and transformative demographic transition. Its experience illustrates how a nation can move from a traditional, high-fertility society to one facing profound challenges associated with aging and low birth rates—all within a few decades.
Rapid Economic Modernization as a Catalyst Following the Korean War, South Korea was one of the world’s poorest nations. However, starting in the 1960s, rapid industrialization and economic growth transformed the country almost overnight. With improvements in healthcare, sanitation, and overall living conditions, mortality rates dropped dramatically. Yet the sharp declines in fertility only followed after these gains were well established—a pattern that fits the classic stages of the demographic transition. In the early years, families continued to have many children, sometimes averaging around six per woman. By the 1990s, as urbanization and educational opportunities expanded—particularly for women—social norms shifted dramatically toward smaller family sizes, with fertility rates dropping to around 1.6 children per woman.
Transitioning Through the Demographic Stages South Korea's journey is often mapped onto the Demographic Transition Model (DTM). Initially, it moved from high mortality and high fertility (Stage 1) to lower mortality in Stage 2. The real shift came in Stage 3, when fertility dramatically fell—a change driven not only by economic factors but also by evolving social attitudes toward marriage, careers, and the cost of raising children. Today, South Korea is considered to be in Stage 4, where both low birth and death rates have led to a stagnant or even declining population. This rapid transition—accelerated by modern policies and the pace of economic development—sets South Korea apart from some traditional Western transitions that often occurred over longer periods.
Contemporary Challenges and Policy Responses The low total fertility rate (TFR) in recent years—down to about 0.84 births per woman in 2020, the lowest in the world—highlights some of the stark societal challenges now facing the nation. An aging population, a shrinking workforce, and the pressure on social welfare systems have become key policy concerns. Government strategies have included financial incentives, enhanced parental leave policies, and improved childcare support, but these measures have yet to reverse the trend significantly. Instead, South Korea now grapples with the long-term consequences of one of the most rapid and profound demographic transitions in modern history.
South Korea’s case not only reflects the universal forces described by demographic transition theory but also underscores the unique challenges that arise when modernization occurs at breakneck speed. Would you be interested in exploring how these demographic shifts are influencing South Korea's economic strategy or what lessons other rapidly developing nations might learn from its experience?
