Fertility in High-Income Countries: Trends, Patterns, Determinants, and Consequences
Open accessAbstract
High-income countries have generally experienced falling fertility in recent decades. In most of these countries, the total fertility rate is now below the level that implies a stable population in the long run. This has led to concerns among economists, policymakers, and the wider public about the economic consequences of low fertility and population decline. In this contribution, we aim to ( a ) describe the main determinants of low fertility in high-income countries, ( b ) assess its potential economic consequences, ( c ) discuss adjustment mechanisms for individuals and economies, ( d ) propose a simple economic framework to analyze the long-run economic impacts of low fertility, and ( e ) draw lessons for economic policymakers to react appropriately. While the economic challenges of low fertility are substantial, a thoughtful and consistent policy response can mitigate most of the adverse consequences.
Overview

Written from the paper’s full text.
TL;DR
High-income countries have generally experienced falling fertility, with the OECD total fertility rate dropping from 3.29 children per woman in 1960 to 1.63 in 2019 and most countries now below replacement. The review argues that low fertility creates substantial economic challenges, but compensatory mechanisms and a coordinated policy mix can mitigate most adverse consequences.
Key findings
- Across OECD countries, the total fertility rate fell from 3.29 children per woman in 1960 to 1.63 in 2019; all countries in Table 1 experienced declines, and except Israel (TFR 3.22 in 2019), 2019 TFRs were below the replacement rate of 2.1. The Republic of Korea had the lowest 2019 TFR at 0.91 and the largest secular decline at −5.04.
- Fertility decline is attributed to multiple determinants: rising opportunity costs of childrearing, especially women’s earnings; quantity-quality trade-offs; family policies; uncertainty and old-age security motives; social norms; childlessness; internet and partnership changes; and post-Great Recession/COVID-19 dynamics.
- Macroeconomic concerns include labor shortages, pressure on pay-as-you-go welfare systems, reduced innovation and entrepreneurship, lower consumption growth, and regional imbalances; compensatory mechanisms include demographic dividends, increased female employment, savings responses, human capital investment, and labor-saving technology.
- The proposed semi-endogenous growth model with human capital and endogenous education/fertility choice yields Result 1: aggregate human capital growth decreases when fertility increases (and vice versa), and Result 2: a negative effect of population growth on economic growth. Policy implications stress that no single policy is a panacea; immigration, family-friendly policies, education and health investment, R&D, later retirement, and policy synergies are needed.
Methods
- Design: literature review plus a simple theoretical extension of a semi-endogenous growth model with human capital and endogenous fertility and education choices.
- Data/sample: OECD country total fertility rates for 1960, 2019, and 2021 from United Nations (2022) and World Bank (2023), presented in Table 1; narrative synthesis of cited empirical and theoretical literature.
- Main analysis: descriptive comparison of TFR trends; review of determinants and macroeconomic consequences; derivation of model results linking fertility, human capital growth, and long-run economic growth.
Limitations
- The paper states that its model deliberately switches off the reverse channel from income to fertility and focuses on the economic consequences of changing fertility choices; it captures mainly the quantity-quality trade-off as a long-run compensation mechanism, and many extensions are possible.
- The paper notes unresolved evidence in the literature, including that the extent of male sperm-count effects remains unresolved, evidence on climate anxiety and voluntary childlessness is inconclusive, and the extent to which human capital improvements offset population aging or decline is unclear.
- Evident from the text: as a review, it does not provide new empirical estimates; its quantitative claims rely on cited studies and a simple theoretical model rather than original causal identification.

The Introduction reports that aging explains about 35% of cross-country variation in robot adoption and compares its estimated effect with the average increase in robots per thousand workers during the study period. The Results section also finds a sizable association between aging and increases in robots per worker. This supports the claim about demographic factors explaining a large part of observed increases, particularly differences across countries. (LLM, conf=0.91)

The Discussion and research avenues section (page unavailable) says fertility postponement arises from changing economic conditions and that people who wish to have children need support.

The Cohort Trends in Marriage and Fertility section reports that South Korean women delayed childbirth and that later births did not fully make up for the decline among the 1970s cohorts.

It therefore supports the claim’s broad idea, not a definite finding that those conditions determine whether delayed fertility is recuperated. (LLM, conf=0.84)

Many countries have to support their pay-as-you-go pension or healthcare systems with a substantial part of their tax revenues.
“As a consequence, many countries have to support their pay-as-you-go pension or healthcare systems with a substantial part of their tax revenues.”
The authors state this as an assumption.
Time t evolves discretely.
“We assume that time t evolves discretely because including a realistic human capital accumulation process in the model is then straightforward.”
The authors state this as an assumption.
The production side of the economy is the same as posited by Jones (1995), except that the knowledge production function features the human capital embodied in the scientific workforce instead of the number of scientists.

Households derive utility from consumption, the number of own children, and the education the children enjoy, with decreasing marginal effects.
“On the consumption side, households derive utility from consumption ( c t ), from the number of own children ( nt ), and from the education the children enjoy ( e t ), reflecting intergenerational altruism. Utility is increasing in all of these arguments but with a decreasing marginal effect.”
The authors state this as an assumption.
A hierarchy of needs holds according to which households prioritize first consumption, then procreation, and finally education, ensured if 1 > α > η > 0.
“For meaningful results, a hierarchy of needs has to hold according to which households prioritize first consumption, then procreation, and finally education. This is ensured if 1 >α > η > 0.”

The costs of children are modeled as forgone parental labor income due to time spent on childcare, and each child requires ψ units of parental time.
“The wage rate is denoted by w t , and the costs of children are modeled as forgone parental labor income due to the time spent on childcare. Assuming that each child requires ψ units of parental time, normalizing parental time endowment to 1, and denoting the price of education by ξ , we have the following household budget constraint:”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
