Global Development Lessons from the Sharp Decline in US Poverty: Governance, Transfer Payments, and Long-Term Sustainability

Introduction: The Truth About Poverty Reduction Revealed by an 84-Year Tracking Study

In 2025, the Civitas Institute and the American Enterprise Institute jointly released a U.S. poverty data series covering 1939 to 2023—the longest-ever measurement of poverty rates incorporating taxes, transfer payments, and health insurance factors. The findings are encouraging: a typical American born in 1939 would witness a dramatic decline in poverty rates by 2023, with living standards improving at a rate that ranks among the greatest successes in human history.

However, this progress is not the direct result of any single policy (such as President Johnson’s “War on Poverty” in the 1960s), but rather the outcome of the long-term evolution of multidimensional governance mechanisms. For global development researchers and policymakers, the U.S. case offers profound lessons on “what actually works”: poverty reduction depends on institutional transfer payments, tax redistribution, public service coverage, and the expansion of economic opportunities—and the sustainability of these elements relies on strong governance structures.

Data-Driven Governance: From “War” to Measurable Systems

Traditional narratives often attribute the decline in U.S. poverty to the “War on Poverty” launched in 1964 and subsequent social welfare programs. But new research shows that the real turning point occurred later and was closely tied to the specific design of policies. For example, tax credits (such as the Earned Income Tax Credit, EITC) and in-kind transfers (such as food stamps and Medicare) gradually expanded after the 1970s, making significant contributions to reducing poverty rates.

This finding has fundamental implications for global development: Development policies cannot remain mere slogans or one-off projects; they require the establishment of an institutional framework for continuous monitoring and gradual adjustment. Many developing countries, when imitating developed nations' poverty reduction programs, often neglect the construction of data infrastructure and impact evaluation mechanisms. The U.S.’s 84-year data series itself is a governance asset—it can identify which interventions are truly effective and which need reform.

The Global South Perspective: The “Sustainability Trap” of Transfer Payments and Social Security

The U.S. experience also reminds us: the success of poverty reduction may bring new governance challenges. When transfer payments become the norm, issues of fiscal sustainability, labor market incentives, and intergenerational mobility arise. This is precisely the reflection of the “middle-income trap” that many middle-income countries (such as Brazil and India) currently face in the dimension of poverty reduction.

The “Social” pillar under the ESG framework increasingly focuses on long-term inclusive growth. The U.S. case shows that cash transfers alone cannot address the structural roots of poverty—education gaps, health inequality, and the digital divide. For example, although health insurance covers low-income groups, disparities in health outcomes persist. For global development institutions, this means that when evaluating national poverty reduction programs, they should examine whether the programs are complemented by investments in education, skills training, and employment promotion measures.

The Intersection of Climate, Energy Transition, and Poverty Governance

Notably, the period of U.S. poverty decline also coincided with the economic structure transitioning from manufacturing to services and the digital economy.## The Intersection of Climate, Energy Transition, and Poverty Governance

Notably, the period of declining poverty in the United States also coincided with the transformation of the economic structure from manufacturing to services and the digital economy. Current climate actions and energy transitions may have asymmetric effects on the poor—the cost of clean energy, carbon taxes, and industrial relocation could all exacerbate new inequalities.

The Low-Income Home Energy Assistance Program (LIHEAP), launched by the United States after the oil crisis in the 1970s, provides a cross-sectoral governance case: incorporating energy equity into poverty reduction policies. Currently, global climate finance frameworks (such as the Green Climate Fund) increasingly emphasize a "Just Transition," which draws precisely from the U.S. experience—poverty reduction cannot be separated from climate action. When developing countries plan their low-carbon pathways, they must simultaneously establish compensation mechanisms for vulnerable groups.

Re-anchoring International Cooperation: From Aid to Capacity Building

Behind the decline in U.S. poverty is a strong federal government capacity and a mature tax system. For many least developed countries, what is lacking is not poverty reduction plans, but the administrative resources, data capabilities, and anti-corruption mechanisms needed to implement these plans. Therefore, international development cooperation needs to shift from "project delivery" to "capacity co-building."

The "Country Platforms" promoted by the World Bank and UNDP in recent years are a manifestation of this approach: through long-term technical assistance and results-based financing, helping countries build their own data monitoring systems and transfer payment mechanisms. The 84-year data series study in the U.S. also shows that evaluating policy effects takes decades—this requires international investors and development institutions to have long-term patience.

Conclusion: A New Paradigm of Long-term Sustainability

The sharp decline in the U.S. poverty rate proves that humanity has the ability to significantly improve people's livelihoods through institutional and policy choices. But this success was not automatic; it was accumulated through continuous trial and error, data feedback, and governance adjustments. For the global development field, the core proposition is no longer just "how to replicate the U.S. poverty reduction results," but "how to build sustainable governance systems in diverse political and economic environments."

• ESG investors and policy analysts should focus on the following long-term signals:
• Has the country established a mechanism for regular collection and publication of dynamic poverty data?
• Does the transfer payment system complement labor market, education, and health policies?
• Do climate actions include compensation provisions for vulnerable groups?
• Is international cooperation shifting from short-term aid to long-term governance capacity building?

Only by embedding poverty reduction into deeper governance reforms can we ensure that in the next 84 years, more countries can also write their own success stories.
