Global Decline and Divergence – WHO Total Fertility Rate (TFR) Data by Region
Total Fertility Rate (TFR): A Key Demographic Indicator
The Total Fertility Rate (TFR) is one of the most important metrics used in demography and population studies. It provides an estimate of the average number of children a woman would have over her lifetime if she were to experience the current age-specific fertility rates throughout her childbearing years.
Definition and Interpretation
The TFR is a hypothetical measure that is based on the fertility rates of a specific population during a particular period (usually a calendar year). It is expressed as children per woman.
| Concept | Explanation | Value |
| Definition | The average number of children a woman would have if she survived to the end of her reproductive years (typically 15-49) and experienced the prevailing age-specific fertility rates of a given year. | $\text{Children per woman}$ |
| Replacement Level | The TFR required for a population to exactly replace itself over the long term, assuming no net migration. It accounts for the small chance that not all children will survive to adulthood and the slight imbalance in the sex ratio at birth. | $\approx 2.1$ children/woman |
| Above Replacement | A TFR greater than 2.1, indicating that, in the absence of migration and changes in mortality, the population will likely grow. | $> 2.1$ children/woman |
| Below Replacement | A TFR less than 2.1, indicating that, in the absence of migration and changes in mortality, the population will likely eventually shrink. | $< 2.1$ children/woman |
Significance of TFR
The TFR is a better indicator of fertility trends than the Crude Birth Rate (which is just the annual number of births per 1,000 people) because it is independent of the age structure of the population.
Population Growth: TFR is a primary determinant of a country's long-term population growth or decline. A sustained TFR below the replacement level of $\approx 2.1$ signals a potential future decline in population size and an aging population.
Socio-economic Development: TFR is often inversely correlated with socio-economic development. Generally, developed countries have lower TFRs, which correlates with factors like:
Higher levels of female education and labor force participation.
Increased urbanization.
Better access to and use of contraception.
Delayed family formation and childbearing.
Policy Planning: Governments and planners use TFR to anticipate future demands on social services, such as education, healthcare (especially for the elderly), and pension systems.
Calculation Method
The TFR is calculated by summing the Age-Specific Fertility Rates (ASFRs) for women across their childbearing years (usually 15 to 49).
The ASFR is the number of births to women in a specific age group divided by the number of women in that age group. It is usually expressed as births per 1,000 women.
To find the TFR:
Calculate the ASFR (expressed as births per woman, i.e., divide by 1,000) for each age group (e.g., 15-19, 20-24, etc.).
Sum the ASFRs.
If 5-year age groups are used, multiply the sum by 5 (the length of the age interval).
Note: When ASFR is given per 1,000 women, the final result must be divided by 1,000 to get the TFR in terms of children per woman.
TFR vs. Completed Fertility Rate (CFR)
It's important to understand that the TFR is a period measure, reflecting fertility at a specific point in time. It is not the same as the Completed Fertility Rate (CFR), which is the actual average number of children born to a specific cohort of women by the end of their reproductive lives.
A common temporary phenomenon that can skew the TFR is the tempo effect. If women delay childbearing to later ages, the TFR can temporarily drop, even if the eventual (completed) number of children they have remains the same. The TFR provides an immediate, cross-sectional snapshot, while the CFR gives a complete, long-term picture.

The Shrinking Family: Countries with the Lowest Total Fertility Rate (TFR) 📉
The Total Fertility Rate (TFR), a critical demographic indicator, represents the average number of children a woman would have over her lifetime if she were to experience the current age-specific fertility rates. A TFR of approximately 2.1 births per woman is generally considered the replacement level—the rate needed to keep a population stable without migration.
Globally, fertility rates have been falling, but some nations have seen their TFR drop to extremely low levels, often referred to as "lowest-low fertility" (at or below 1.3). These low rates are primarily concentrated in East Asia and parts of Europe, raising significant demographic and economic concerns about aging populations and shrinking workforces.

Note: TFR figures can vary slightly based on the data source, year of estimation, and methodology used by different organizations (e.g., UN, World Bank, national statistics).
The Phenomenon of Lowest-Low Fertility
The countries listed are consistently at the forefront of the global low-fertility trend. For instance, South Korea has the most dramatically low TFR among sovereign nations, consistently setting new records for the world's lowest rate.
Low fertility in these regions is not typically due to high mortality but is rather a reflection of societal and economic factors that influence family planning decisions.
Key Contributing Factors:
High Cost of Raising Children: Soaring expenses for education, housing, and childcare make having multiple children financially challenging, particularly in high-cost-of-living urban areas.
Intense Educational Competition: The pressure on parents to invest heavily in their children's education ("education fever") to ensure future success can deter them from having more children.
Career and Gender Equality Shifts: As women achieve higher levels of education and participate more fully in the workforce, they often postpone or choose to have fewer children due to the difficulty of balancing demanding careers with traditional expectations of motherhood.
Delayed Marriage and Childbearing: Economic uncertainty, longer educational paths, and changing social norms contribute to a trend where individuals are marrying and having children much later, which naturally leads to fewer lifetime births.
Lack of Government Support: Despite government incentives in many of these countries (like Japan and South Korea), the social infrastructure (e.g., affordable, high-quality childcare and workplace flexibility) often hasn't kept pace with the needs of working parents.
Demographic and Economic Impact
Sustained low TFRs below the replacement level have profound long-term consequences, primarily leading to population aging and eventual population decline.
Population Aging: As birth rates fall and life expectancy increases, the proportion of elderly people in the population rises dramatically. This creates a demographic pyramid that is top-heavy, straining social security, healthcare systems, and long-term care resources.
Labor Shortages: A smaller cohort of young people entering the workforce struggles to support a growing number of retirees. This can lead to labor shortages, reduced economic productivity, and potential difficulties in maintaining public services.
Fiscal Pressure: Governments face significant fiscal challenges as tax revenues shrink (due to fewer workers) while social expenditure for the elderly increases.
Addressing this demographic trend often involves governments introducing a combination of financial subsidies, parental leave policies, expanding public childcare, and making structural changes to reduce the economic burden and social expectations placed on parents.

South Korea's Total Fertility Rate (TFR) Crisis 🇰🇷
South Korea is currently grappling with the world's lowest Total Fertility Rate (TFR), a demographic crisis that poses significant long-term challenges to its society and economy. The TFR—the average number of children a woman is expected to have in her lifetime—has been in steady decline for decades, falling far below the replacement level of 2.1 births per woman necessary to maintain a stable population without immigration.
The Declining Trend
The nation has seen a dramatic drop in its TFR since the post-war era, moving from high fertility in the 1960s to what is internationally defined as a "lowest-low fertility" society (a TFR below 1.3) since the early 2000s, and recently sinking below $0.80.
| Year | Total Fertility Rate (TFR) | Status Relative to Replacement Level (2.1) |
| 1960 | $\sim 6.33$ | Far Above |
| 1970 | $\sim 4.2$ | Above |
| 1983 | Below 2.1 | Below (Entered Low Fertility Society) |
| 2002 | $\sim 1.18$ | Below (Entered Lowest-Low Fertility Society) |
| 2018 | $0.98$ | First Time Below 1.0 |
| 2021 | $0.81$ | Dramatically Low |
| 2022 | $0.78$ | World's Lowest |
| 2023 | $0.72$ | Continues to Decline (World's Lowest) |
Key Contributing Factors to the Low TFR
The sustained decline is driven by a complex interplay of socioeconomic and cultural factors, making the issue difficult to resolve despite significant government investment in pro-natal policies.
1. High Economic Burden 💸
The financial cost of raising a child in South Korea is among the highest in the world. This includes:
Exorbitant Housing Costs: Especially in the Seoul Metropolitan Area, high housing prices make it difficult for young couples to afford the necessary living space to start a family.
Intense Educational Competition: The culture of fierce academic competition necessitates massive spending on private tutoring ($hagwon$), which places an enormous financial strain on parents.
2. Work-Life Imbalance and Career Interruption 💼
Many women feel they must choose between career and motherhood, a dilemma often referred to as the "child penalty."
Long Working Hours: Korea is known for long working hours, making it challenging for both parents to balance professional life with childcare.
Disproportionate Childcare Burden: Traditional expectations and a lack of supportive workplace infrastructure mean the bulk of childcare and housework still falls on women, leading many to delay or forgo having children to protect their careers.
3. Delayed and Declining Marriage Rates 💍
In South Korea, most births occur within marriage. Therefore, the significant trend of young adults delaying marriage or choosing not to marry at all directly contributes to the low birth rate. Factors include financial precarity, high expectations for a spouse's economic status, and changing social values.
Consequences and Outlook
The persistently low TFR has profound demographic implications:
Population Decline: The nation's population has begun a natural decline (more deaths than births), and projections indicate a severe shrinkage by the end of the century.
Rapid Aging: The decline in births, combined with a high life expectancy, results in the world's fastest-aging society. This strains the workforce and the national pension/healthcare systems, as fewer working-age adults support an increasing number of retirees.
Economic Impact: A shrinking working-age population is expected to lower South Korea's economic growth potential and reduce labor supply.
While the government has implemented multiple, large-scale policy packages—including cash incentives, expanded parental leave, and public childcare support—the fundamental structural and cultural obstacles have proven resistant to change. Addressing the crisis requires deeper societal shifts, particularly in achieving a better work-life balance and a more equitable distribution of caregiving responsibilities.

Taiwan's Total Fertility Rate (TFR): A Deepening Demographic Crisis 🇹🇼
Taiwan is experiencing one of the world's most severe demographic declines, with a Total Fertility Rate (TFR) consistently ranking among the lowest globally. The TFR, which measures the average number of children a woman is expected to have in her lifetime, has fallen far below the replacement level of 2.1, leading to rapid population aging and an imminent decline in the overall population.
Taiwan achieved the replacement level in 1984 and has since seen a dramatic, near-continuous decline. The TFR has repeatedly fallen below $\mathbf{1.0}$, cementing Taiwan's status in the "lowest-low fertility" category.
Historical Trend of Taiwan's Total Fertility Rate
The following table highlights the precipitous drop in Taiwan's fertility rate from post-war highs to its current crisis levels.
| Year | Total Fertility Rate (TFR) | Status Relative to Replacement Level (2.1) |
| 1960 | $\sim 5.85$ | High Fertility |
| 1970 | $\sim 3.96$ | Above Replacement |
| 1984 | $\sim 2.14$ | Reached Replacement Level |
| 1990 | $\sim 1.76$ | Below Replacement |
| 2010 | $\sim 0.89$ | Historical Low (World's Lowest at the time) |
| 2022 | $0.87$ | Among the World's Lowest |
| 2023 (Est.) | $\mathbf{0.85}$ | Lowest-Low Fertility Society |
Key Drivers of Taiwan's Low TFR
The sustained low TFR is a result of complex societal and economic pressures that have made marriage and child-rearing less appealing for the younger generation:
1. High Financial and Economic Pressures 💰
Skyrocketing Housing Costs: The unaffordability of housing, particularly in urban areas, is a major deterrent for young couples considering marriage and starting a family.
Stagnant Wages: Despite strong economic growth, wage increases have not kept pace with the rising cost of living, making it difficult for many young men and women to feel financially secure enough to support children.
2. The Persistence of Traditional Gender Roles 젠더
"Incoherence" in Gender Expectations: While women have achieved high levels of education and labor force participation (reflecting an egalitarian social model), traditional expectations for wives to handle the majority of housework and childcare persist within the family.
Career Interruption for Women: This dual burden creates a significant disincentive for highly educated and career-focused women, often leading them to delay or forgo marriage and motherhood.
3. Delayed Marriage and Marriage Avoidance 💒
Children as a Pre-Marital Event: Taiwan has a very low rate of births outside of marriage, making the decline in the marriage rate a direct precursor to the fertility crisis.
Older Age at First Birth: As both men and women pursue longer education and careers, the average age of first marriage and first childbirth has significantly increased, naturally shortening the childbearing window.
Societal and Policy Implications
The demographic shift has severe consequences. Taiwan officially became an "aged society" (over $14\%$ of the population over 65) in 2018 and is projected to become a "super-aged society" (over $20\%$ of the population over 65) by 2025.
The government has introduced various pro-natalist policies, including cash subsidies, enhanced parental leave, and subsidies for in-vitro fertilization (IVF). However, the demographic trend suggests that financial incentives alone are insufficient. Long-term success will require fundamental cultural changes, greater gender equity in the home, and structural reforms to reduce the economic burden on young families. The shrinking pool of working-age adults threatens the long-term sustainability of the national workforce, tax revenue, and military service recruitment.

The Total Fertility Rate (TFR) in Ukraine 🇺🇦: A Deep Decline
Ukraine's Total Fertility Rate (TFR) has been on a long-term downward trend, and in recent years, it has dropped to one of the lowest levels in the world. The TFR, which measures the average number of children a woman would have in her lifetime, is a critical indicator of demographic health. For a population to replace itself without migration, the TFR must be around 2.1 births per woman (known as the replacement level). Ukraine has been far below this for decades, and the geopolitical conflict has accelerated the decline.
The sharp drop in the TFR highlights a significant demographic challenge, particularly when compounded by high emigration and war-related fatalities, leading to a rapidly aging and shrinking population.
Historical and Recent TFR Data
The table below shows the decline in Ukraine's Total Fertility Rate, illustrating the country's severe demographic shift. The data reflects a continuous fall in fertility since the post-Soviet era, with a notable and dramatic decrease observed in 2022 following the full-scale invasion.
| Year | Total Fertility Rate (TFR) (Births per Woman) | Notes |
| 1986 | 2.12 | Modest increase during a Soviet-era family policy package, reaching replacement level. |
| 1990 | 1.85 | Beginning of the post-Soviet decline. |
| 2000 | 1.11 | Reached a historic low in the post-Soviet economic crisis. |
| 2010 | 1.44 | A period of slight recovery. |
| 2015 | 1.39 | Decline resumes after 2013. |
| 2019 | 1.22 | Pre-pandemic and pre-invasion level. |
| 2021 | 1.15 | Year prior to the full-scale invasion. |
| 2022 | 0.90 | Sharp decline following the full-scale invasion, making it one of the lowest in the world. |
| 2023 | 0.98 | Remains at a severely low level. |

Factors Driving the Low TFR
The low and decreasing TFR in Ukraine is the result of long-term and immediate factors:
Lowest-Low Fertility Trend: Ukraine has been part of a broader European trend of "lowest-low fertility" (TFR below 1.3) since the early 2000s. This is primarily driven by socio-economic factors like the postponement of childbearing, urbanization, and changing family norms.
Economic and Political Instability (Post-1991): The transition following the collapse of the Soviet Union brought severe economic hardship and uncertainty throughout the 1990s and early 2000s, directly correlating with the sharp drop in TFR to around 1.1.
Impact of Conflict (Post-2014 and especially Post-2022): The full-scale invasion that began in February 2022 has had a catastrophic demographic impact. The extreme uncertainty and insecurity caused by the war have led to:
Massive emigration of women of childbearing age, who often postpone having children while abroad.
Internal displacement and a generalized reluctance to have children amid constant threat.
Direct disruption of health services and infrastructure.
The TFR of 0.90 in 2022 is a historic low for the country and places Ukraine among the countries with the lowest fertility rates globally. This deeply challenging demographic trend means that without substantial future interventions or mass immigration, Ukraine's population will continue to age and decline rapidly.

Singapore's Total Fertility Rate (TFR): A Demographic Crossroads 🇸🇬
Singapore is grappling with one of the most pressing demographic challenges globally: a persistently low Total Fertility Rate (TFR). This key metric, which measures the average number of children a woman is expected to have in her lifetime, has fallen to historic lows, placing the nation far below the replacement level of $2.1$ required to sustain the population without immigration.
According to the latest preliminary data, Singapore's resident TFR hit a record low of $0.97$ in 2023, and remained unchanged in 2024. This is the first time the TFR has dipped below $1.0$, a significant milestone that underscores the severity of the issue, even failing to see a traditional lift during the auspicious Chinese Year of the Dragon in 2024.
TFR Trend: A Steady Descent
The rapid decline in Singapore’s TFR reflects a successful but now-reversed public policy drive from the 1960s ("Stop at Two") and the profound socio-economic shifts that followed. The trend shows a relentless drop from post-independence peaks to its current state, as illustrated below:
| Year | Resident TFR (Births per woman) | Notes |
| 1965 | 4.66 | Post-World War II baby boom era. |
| 1975 | 2.07 | Fell below the replacement level ($2.1$). |
| 2000 | 1.60 | Dragon Year effect provided a temporary boost. |
| 2010 | 1.15 | Near the modern era's low point. |
| 2022 | 1.04 | Sharp drop preceding the current low. |
| 2024 | 0.97 | Historic Low (preliminary data), the TFR remained below $1.0$. |
Underlying Drivers of Low Fertility
The forces pushing the TFR lower are deeply rooted in modern urban life:
Delaying or Forgoing Marriage: The biggest statistical factor is the increasing number of women who are either remaining single or marrying later in life. Since most births are within marriage in Singapore, a delay in marriage shortens the fertile window for childbearing.
Intense Parental Pressure and Cost: The high costs associated with living in Singapore, especially housing, combined with an intense focus on a child's educational and competitive success, lead many couples to opt for smaller family sizes or delay having children until they are financially secure.
Work-Life Integration Challenges: Despite government efforts to promote better work-life balance, many professionals—particularly women—find it difficult to reconcile demanding careers with the intensive requirements of modern parenting. This often results in postponed or foregone births.
Older Age at Childbearing: Even for those who do marry, the trend is to have children at an older average age. While this may increase birth rates in the 35+ age groups, it rarely compensates for the steep decline in births among women in their 20s.
A Matter of National Resilience
The long-term consequences of an ultra-low TFR are significant, accelerating a future where the population ages rapidly. This imbalance results in a dwindling old-age support ratio—fewer working adults supporting a growing number of retirees—which strains public finances, healthcare systems, and the labor market. While immigration is a necessary short-term measure to maintain economic vibrancy, the long-term solution rests on domestic birth rates.
Singapore’s challenge is unique because its robust pro-family policies have struggled to counteract the powerful societal currents of an ambitious, highly urbanized, and competitive society. For the nation to maintain its dynamism and unique social fabric, the next chapter of its development must successfully create an environment where young couples feel they can pursue both their careers and their desired family size without having to sacrifice one for the other.
.jpg "Global Decline and Divergence – WHO Total Fertility Rate (TFR) Data")
Global Decline and Divergence – Key Takeaways from WHO Total Fertility Rate (TFR) Data
The Total Fertility Rate (TFR) data, compiled and used by the World Health Organization (WHO) and other international bodies like the UN Population Division, provides a critical summary of global demographic trends. The overarching conclusion drawn from this data is a dramatic and widespread decline in global fertility, although significant regional disparities remain.
1. Universal Decline Towards and Below Replacement Level
The most striking conclusion is the historic, continuous, and near-universal decline in TFRs since the mid-20th century.
Global Halving: The global average TFR has more than halved since the 1950s (when it was around 5.0 children per woman) and is now near the replacement level of approximately 2.1 children per woman (e.g., 2.3 in 2023, according to some estimates).
Below Replacement: A significant and growing number of countries, particularly in Europe, North America, East Asia, and parts of Latin America, have TFRs well below the replacement level (the rate needed to maintain the population size without migration). This indicates a trend towards potential long-term population decline in these regions.
2. Widening Regional Divergence
While the decline is global, current TFR data highlights a massive divergence in fertility levels across regions:
Highest Fertility: Countries in Sub-Saharan Africa and parts of Central Asia consistently register the highest TFRs, often ranging from 3 to 7 children per woman. This means these regions are the primary drivers of current global population growth.
Lowest Fertility: Countries in East Asia and Southern Europe often exhibit the world's lowest fertility rates (some below 1.0 children per woman), intensifying the challenges of aging populations and labor force contraction.
3. Implications for Population Dynamics
The TFR data leads to profound conclusions regarding future global population structure:
Shift in Global Births: As fertility rates converge but remain high in lower-income countries (particularly in Sub-Saharan Africa), the proportion of global live births is shifting dramatically towards these regions.
Population Aging: In countries with below-replacement TFRs, the conclusion is an accelerating trend of population aging. Lower birth rates combined with increased life expectancy lead to a smaller proportion of youth and a larger proportion of elderly individuals, creating pressure on health, pension, and labor systems.
Tempo and Quantum Effects: Data analysis underscores that the TFR, being a period measure, can be influenced by changes in the timing (tempo) of births (e.g., women delaying having children). This suggests that while TFR may drop quickly, the completed family size (quantum) may not decline as steeply in some populations, though the overall downward trend is undeniable.
4. Underlying Socio-Economic Drivers
While TFR is the outcome, the data strongly supports the conclusion that the global decline is intrinsically linked to socio-economic development and policy implementation:
Empowerment and Education: The decline is consistently correlated with increased female education and economic empowerment, leading women to delay childbearing and choose smaller family sizes.
Access to Contraception: The availability and uptake of modern contraceptive methods through family planning programs (often supported by organizations like WHO) has been a critical factor in enabling women to achieve their desired family size.
Urbanization and Development: Higher levels of economic development and urbanization generally correlate with lower TFRs, as the costs and incentives associated with raising children shift.
In conclusion, WHO-related TFR data confirms that the world is in a rapid demographic transition, characterized by a fundamental shift away from large families. While the global population is still growing due to past high fertility rates, the data clearly projects a future where below-replacement fertility is the norm in most of the world, leading to an inevitable restructuring of societies and economies on a global scale.
