Baby Bump in South Korea as Fertility Rate Rises for First Time in 9 Years

AI Summary. South Korea's fertility rate rose from 0.72 to 0.75 births per woman, its first increase in nine years, though it remains the world's lowest and far below the 2.1 needed for a stable population. Officials partly attributed the rise to an increase in marriages following the pandemic.

South Korea’s fertility rate rose to 0.75 in 2024 vs. 0.72 in 2023, the first increase in 9 years. Officials partly attributed the rise to a post-pandemic increase in marriage; there were 222,422 marriages last year, the highest number since 2019.

Can a rise in marriages lift the world's lowest fertility rate?

Core argument: South Korea's fertility rate rose from 0.72 in 2023 to 0.75 last year, according to the national statistics office, the first increase since 2015, when the rate stood at 1.24.

South Korea’s fertility rate has risen for the first time in nine years, as a surge in marriages after the pandemic has spurred hopes that the world’s fastest-ageing society may have turned a corner. The country’s fertility rate — the average number of babies a woman is expected to have in her lifetime — increased from 0.72 in 2023 to 0.75 last year, according to the latest data from the national statistics office. Although the rate remains the lowest in the world and far below the 2.1 needed to ensure a broadly stable population, this is the first rise since 2015, when it was 1.24. Officials partly attributed the rise to an increase in the number of marriages after the pandemic. There were 222,422 marriages last year, the highest number since 239,159 in 2019.

Falling Fertility: The Changing Value of Freedom, Fulfillment, and Family

AI Summary. Across surveyed countries, intended fertility and the ideal number of children both declined, while children came to be seen more as a constraint on parental freedom and less as a source of status. Gender roles grew less traditional and housework more equally shared, yet the belief that a fulfilled life requires children weakened most of all attitudes measured.

Fernández et al. cast doubt on Goldin’s hypothesis that men’s limited willingness to share domestic responsibilities is central to fertility decline, pointing instead to the erosion of the belief that children are necessary for a fulfilling life.

Are shifting attitudes about children behind falling fertility intentions?

Core argument: Intended fertility fell in every Generations and Gender Survey country, from 28% to 21% on average, while the ideal number of children fell in 17 of 22 International Social Survey Programme countries, from 2.42 to 2.31.

Figure 1 documents how fertility outcomes and attitudes changed over the decade. Intended fertility fell in every GGS country, from 28 to 21% on average (Figure 1a). The ideal number of children fell in 17 of the 22 ISSP countries, from 2.42 to 2.31 on average (Figure 1b). [Children] became more likely to be seen as constraining parental freedom and less likely to be seen as conferring status (Figure 1c). Gender roles became less traditional, and the division of household work became more equal [Figures 1i]. Despite this greater sharing of chores and care, work–family conflict rose sharply. The decade saw changes that might have been expected to make the burden of children lighter, at least for women. Simultaneously, however, children became less attractive and, above all, less necessary: the belief that a fulfilled life requires children lost more ground than any attitude we measure [Table 2, Part II, Panel B].

Terra Incognita: The Economics of a Shrinking World

AI Summary. Global fertility is likely below the replacement level needed to keep population constant in the long run, though population momentum from large cohorts of women now having children means world population will keep growing for roughly another 30 years. Unless trends change, it is projected to peak near 9bn around 2056 and then decline.

The UN appears to systematically overestimate births; e.g. 33 of 37 countries with high-quality statistics registered fewer births in 2024 than the UN had forecast. Fernández-Villaverde and Norrick infer humanity is below replacement fertility in 2026.

Will world population keep growing even as fertility falls below replacement?

Core argument: As of 2026, humanity is likely to be below replacement fertility, with fewer births than needed to keep population constant in the long run.

In Table A1 we compare the World Population Prospects (WPP) estimates of births in 2022-2023 with the official numbers reported by several countries. [A2 shows the full sample with the deviations.] As of 2026, humanity is likely to be below the replacement fertility level: we are having fewer births than we need to keep population constant in the long run. This astonishing fact does not mean that population has stopped growing. Because of momentum effects (the large cohorts of women born two or three decades ago are having their children now, and their own parents have not died yet), world population will keep growing for another 30 years or so. But unless trends change, it will peak at roughly 9 billion around 2056 and then start falling, first slowly, then fast.

  1. As of 2026, humanity is likely to be below replacement fertility, with fewer births than needed to keep population constant in the long run.

The authors find a standard neoclassical growth model calibrated to each country's working-age population tracks output per working-age adult in most economies.

Americans Are Done With Being Put in Racial Boxes

AI Summary. Immigration from Asia and Latin America has been the chief driver of rising US diversity and the declining non-Hispanic White share of the population. Intermarriage across racial and ethnic lines is far more common among Hispanic and Asian Americans, and rising among Black and non-Hispanic White Americans, leaving more people outside single racial categories.

Less than half of Americans < 29 years old are non-Hispanic whites. As of 2020, 33.8mm Americans – 10.2% of the population – identify as being of two or more races, largely driven by intermarriage between whites and either Hispanics or Asian Americans.

Are immigration and intermarriage making single racial categories obsolete?

Core argument: Immigration from Asia and Latin America since the 1960s has been the chief driver of rising U.S. diversity and the declining non-Hispanic White share of the population.

The increase in immigration from Asia and Latin America since the 1960s has been the chief driver of the rise in diversity and decline in the non-Hispanic White share of the population. But those immigrants have been doing what generations of immigrants before them did and, well, becoming Americans. Marriages across racial and ethnic lines are much more prevalent among Hispanic and Asian Americans than Black or non-Hispanic White Americans, while intermarriage rates have been rising steadily for the latter two groups, too. As a result, a growing share of Americans just isn’t going to fit neatly into any single racial or ethnic category that the US government can come up with.

The Pig In The Python: US Decennial Labor Flows And Economic Opportunity, 1910–2040

AI Summary. The surge of baby boomers, women, and immigrants entering the US labor force between 1960 and 1980 was difficult for the economy to absorb, and young workers' wages fell sharply after peaking in the early 1970s. The author argues those entrants kept occupying jobs and suppressing demand for new workers until retirement.

Accounting for both inflows and the overhang of previous labor market entrants, Ruggles predicts a labor shortage such that “Americans born in the 2020s might be the first cohort in a half century that earns significantly more than their parents did.”

How does a large influx of workers affect young workers' wages?

Core argument: Wages for young U.S. workers declined sharply after peaking in 1973, as the economy struggled to absorb the influx of workers entering the labor force between 1960 and 1980 from the baby-boom cohort, rising female participation, and increased immigration.

Figure 3A highlights the influx of workers that occurred between 1960 and 1980, as the large baby-boom cohort entered the labor force, female labor-force participation expanded, and immigration rose [see Figure 2 for a detailed breakdown]. It was difficult for the economy to absorb all the new workers, and wages for young people declined sharply after peaking in 1973. Figure 3A does not, however, provide a valid measure of labor-market competition because the baby boomers and newly employed women and immigrants did not suddenly vanish after they entered the labor force; they kept working and occupying jobs until they eventually retired decades later. The glut of workers entering the labor force in the 1970s would continue to stifle demand for new workers until their eventual exit from the labor force, a process that is still in progress. The index of employment competition shown in Figure 3B is [a better] measure of relative cohort size than 3A. It represents the cumulative net labor-market entries over the previous five decades as a % of the working-age population in the current decade. As shown in Figure 1C, we are already seeing signs of an uptick in the wages of young workers, and as the demographic shortage accelerates we may finally see real wages of the young exceed the levels of the early 1970s.

  1. Wages for young U.S. workers declined sharply after peaking in 1973, as the economy struggled to absorb the influx of workers entering the labor force between 1960 and 1980 from the baby-boom cohort, rising female participation, and increased immigration.
  2. Decennial labor-force entries alone misstate labor-market competition, because baby boomers, newly employed women, and immigrants kept occupying jobs and stifling demand for new workers until their retirements, a process still in progress.
  3. An index of employment competition measuring cumulative net labor-market entries over the previous five decades as a percentage of the current decade's working-age population is offered as a better gauge of relative cohort size, with young workers' wages already showing an uptick.

Cross-country evidence from 1950 to 2020 shows that a 1pp lower birth rate is associated with 22 log points (~25%) higher GDP per worker 40 years later and 29 log points (~44%) after 60 years, likely driven by labor-saving technical change.

Do lower birth rates raise output per worker decades later?

Core argument: A 1pp lower birth rate 20 years earlier is associated with 22 log points higher GDP per worker at t+20 and 29 log points by t+40, roughly 0.73 percentage points faster annual growth over the 40-year interval.

Figure 3 traces out how GDP per worker evolves following a 1pp increase in birth rates at t−20. Since cohorts born at t−20 (e.g., 1970) do not enter the working-age population until t = 0 (e.g., 1990), we should observe no response before t = 0; [indeed] the estimated coefficients are ~0 and statistically insignificant before t = 0. Beginning at t = 0, however, higher birth rates are associated with lower GDP per worker, and the negative effects grow progressively larger over time. For example, a 1pp lower birth rate at t−20 is associated with 22 log points higher GDP per worker at t+20 and 29 log points higher by t+40. The latter corresponds to roughly 0.73 percentage points faster annual growth over the 40-year interval. We find that lower birth rates are associated with more labor-saving patents and a growing share of high-tech industries across countries and US commuting zones [Figure 11]. They are also predictive of higher TFP growth across countries and US industries and increased patenting in ICT and broader automation technology classes. Using cross-country variation in WWII-era military and civilian deaths, we present suggestive evidence that the positive growth effects of falling birth rates are primarily driven by the scarcity of younger workers rather than by reductions in population per se [Figure 14]. [Editor’s note: the paper does not grapple with the fiscal consequences of an aging population.]

Takeaways by Macro Roundup® AI

  1. A 1pp lower birth rate 20 years earlier is associated with 22 log points higher GDP per worker at t+20 and 29 log points by t+40, roughly 0.73 percentage points faster annual growth over the 40-year interval.
  2. Estimated coefficients for GDP per worker are near zero and statistically insignificant before affected cohorts enter the working-age population at t = 0.
  3. Lower birth rates are associated with more labor-saving patents, a growing high-tech industry share across countries and US commuting zones, higher TFP growth, and more ICT and automation patenting, with WWII-era death variation offering suggestive evidence that scarcity of younger workers, rather than smaller population, drives the growth effects.

What Demographic Prediction Can and Cannot Achieve

AI Summary. Running standard demographic models—including the Cohort-Component, United Nations World Population Prospects, Lee-Carter, and Lotka-Volterra approaches—across all plausible analytical choices yields a wide range of possible global population outcomes for 2050 and 2075. The authors argue that presenting a single population trajectory hides the compounding uncertainty inherent in such projections.

Simulation of the decision chain yielding projections of world population in 2050 that range from 6 to 14B suggests most of the variance in demographic forecasts arises not from parameter uncertainty or data randomness but from model choice.

How much uncertainty do single-trajectory population projections hide?

Core argument: Propagating all plausible analytical choices through global population projections to 2050 and 2075 yields wide overall uncertainty distributions, with the Cohort-Component, UN World Population Prospects, Lee-Carter and Lotka-Volterra models showing distinct sensitivities and outcomes.

We explore demographic predictions by propagating all plausible choices that can be made during the analysis through the modelling process. This approach involves navigating the so-called ’garden of forking paths’—mimicking in silico what would happen if multiple investigators were to examine the same problem. For this, we now abandon [the Chinese government mathematician] Song Jian’s ‘historic’ model and turn to models currently in use: the Cohort-Component and UN WPP models, the Lee-Carter model and the Lotka-Volterra model. Note that in standard use, these tools are used in isolation, see e.g. the FAO’s How to Feed the World in 2050, resting on a single UN WPP population trajectory shielding the reader from the compounding effect of their uncertainty. Unsurprisingly, the exercise capturing the modelling of the modelling process for global population projections to 2050 and 2075 reveals distinct characteristics regarding the sensitivity and projection outcomes of the different models. Once abandoned the straitjacket of Song’s approach, uncertainty is free to manifest itself. The overall uncertainty distributions of the projected populations show a wide range of possible outcomes, reflecting the inherent uncertainties in demographic projections.
