Incarceration has become one of the most visible and controversial features of criminal justice systems across the Americas. While extreme imprisonment is often associated with authoritarian regimes or failed states, some of the highest and fastest-growing incarceration rates in the hemisphere have emerged within democratic systems. This raises a deeper institutional question: how do democracies govern crime, insecurity, and social inequality, and why does confinement so often become the preferred policy response?
A comparison between the United States and Argentina offers a revealing lens. The two countries differ significantly in legal tradition, political history, and economic structure. Yet both have experienced dramatic expansions in incarceration over the past several decades. Examining these trajectories side by side helps clarify whether mass imprisonment is simply a response to crime or whether it reflects broader structural features of democratic governance.
Mass Incarceration in the United States
In the United States, incarceration rates are often the first thing that comes to mind when discussing prisons as a public issue. Although these rates peaked around 2008 and have started to decline since then, the U.S. still incarcerates individuals at one of the highest rates in the world, exceeding the rates of many authoritarian regimes (Widra, 2024). The U.S. holds about 5% of the world’s total population, yet it accounts for 20% of the world’s prisoners (Wagner & Bertram, 2020). The increase in incarceration rates has been disproportionate to changes in violent and property crime rates, which peaked in the early 1990s and have since declined significantly.
Despite the gradual decrease in incarceration rates, prison sentences are becoming more stringent, leading to longer periods of confinement for inmates. Over the past few decades, policy changes have generally favored harsher sentences rather than more lenient ones. Scholars often attribute these changes to a cultural demand for “tough on crime” legislation. Consequently, policymakers seek to outperform their opponents to secure votes, leading to excessively long prison terms. As of 2024, life sentences are at an all-time high, with about 1 in 6 prisoners in the U.S. serving life sentences (Nellis & Barry, 2025).
Racial Disparities in Democratic Punishment
These high incarceration rates and lengthy sentences are particularly problematic in the U.S. because they perpetuate a system of racial inequality. People of color, especially Black and Hispanic individuals, are grossly overrepresented in the prison population. While Black individuals make up about 14% of the U.S. population and Hispanics about 19%, by 2025, Black individuals occupied around 41% of the prison and jail population, while Hispanics made up about 20% (Sawyer & Wagner, 2025). With criminal records, racial minorities face increased difficulties in securing employment, applying for home loans, and obtaining certain government benefits, such as SNAP (Supplemental Nutrition Assistance Program, formerly known as “food stamps”).
Thanks to policy reforms, including changes to drug sentencing laws, diversion programs, and broader efforts to move away from mass incarceration, the rates of incarceration for Black and Hispanic Americans have significantly decreased since the early 2000s. For instance, the lifetime likelihood of imprisonment for Black men has dropped from approximately 1 in 3 to about 1 in 5 for those born between 1981 and 2001 (Ghandnoosh, 2023). However, stark racial disparities in imprisonment rates persist.
Argentina and the Expansion of Democratic Incarceration
If the United States illustrates one path of democratic incarceration, Argentina depicts another. Like the United States, Argentina has experienced a significant increase in incarceration over the past two decades. Since the early 2000s, the national incarceration rate has more than doubled, rising from approximately 123 individuals per 100,000 inhabitants in 2001 to 256 per 100,000 in 2024, according to national data compiled from SNEEP and summarized by the Comisión Provincial por la Memoria (CPM, 2025). This growth has accelerated in recent years, with the prison population increasing by roughly 7 to 8 percent between 2023 and 2024 and growing by approximately 75 percent since 2014 (Ministerio de Justicia y Derechos Humanos, 2024). With the exception of a brief decline during the COVID-19 pandemic in 2020, the overall trend has remained upward (CPM, 2025).
This expansion has generated measurable institutional strain. The 2024 SNEEP census reports an average national overcapacity rate of 22.9 percent (Ministerio de Justicia y Derechos Humanos, 2024). The Comité Nacional para la Prevención de la Tortura estimates that overall occupancy is approximately 130 percent of available space (CNPT, 2025), corresponding to more than 30 percent overpopulation, using a different methodology to assess capacity.
Demographic Concentration and Pretrial Detention
The demographic profile of the incarcerated population highlights broader patterns of social concentration. As of December 2024, approximately 95 to 96 percent of incarcerated individuals were male, more than half were under the age of 35, and the majority had completed only primary education or less (Ministerio de Justicia y Derechos Humanos, 2024). These characteristics indicate that confinement disproportionately affects young men with limited educational attainment, groups that already face structural barriers in labor markets and social mobility.
At the same time, the composition of confinement has evolved. By 2024, roughly 60 percent of incarcerated individuals had received a sentence (Ministerio de Justicia y Derechos Humanos, 2024), while more than 45,000 individuals remained in pretrial detention nationwide (CNPT, 2025). Additionally, over 12,000 people were under domiciliary detention or electronic monitoring at the end of the year (Ministerio de Justicia y Derechos Humanos, 2024). Thus, use of alternative custodial measures appears to be growing, even as the total number of persons deprived of liberty continues to rise.
Converging Incarceration Rates in Two Democracies, 2002–2024
Figure 1 illustrates the contrasting trajectories of incarceration in the United States and Argentina between 2002 and 2024. At the beginning of the period, the United States incarcerated at nearly four times Argentina’s rate. Over the next two decades, however, the gap narrowed substantially. While U.S. prison rates declined from their late-2000s peak, Argentina’s rate more than doubled. By 2024, the difference between the two countries had shrunk to just over 100 prisoners per 100,000 inhabitants. The trajectory suggests not divergence, but partial convergence between two democratic systems.
Overall, the trajectories of the United States and Argentina indicate that rising or persistently high incarceration rates are not limited to a single institutional model. One system has plateaued at historically extreme levels, while the other continues to expand. However, in both cases, this growth has occurred within democratic political frameworks.
Why Do Democracies Expand Punishment?
Although the United States and Argentina have different institutional designs and historical paths, both countries operate democratic systems in which incarceration has expanded dramatically over the past several decades. By the late 2000s, the United States reached historically unprecedented levels of incarceration and continues to imprison at one of the highest rates in the world, despite modest declines. Argentina, meanwhile, remains in a phase of sustained expansion, with incarceration rates rising through 2024. In both cases, growth occurred within competitive electoral systems rather than under authoritarian rule.
Comparative research complicates the assumption that extreme incarceration is inherently a feature of authoritarian governance. Cross-national analyses suggest that more democratic systems often exhibit greater procedural safeguards and lower incarceration throughput than authoritarian regimes (Sung, 2006). Yet the United States has long stood out among advanced democracies for its reliance on imprisonment. The Argentine case now suggests that punitive expansion can also take hold in other democratic contexts under conditions of political pressure, institutional incentives, and public anxiety about crime.
Electoral Incentives and Institutional Dynamics
Democratic governance, in other words, does not inherently restrain punitive expansion. Electoral incentives and responsiveness to public opinion have, in some contexts, contributed to punitive expansion within democratic systems (Enns, 2016). Political leaders often face limited immediate electoral costs for expanding incarceration, while the long-term social consequences are diffuse and borne disproportionately by marginalized communities.
The comparison, therefore, indicates that mass incarceration is not simply a function of regime type or temporary crisis. It can become embedded within democratic institutions themselves. When confinement becomes a routine response to social insecurity, inequality, or administrative strain, it risks evolving from a criminal justice instrument into a broader mechanism of social management. In both countries, incarceration disproportionately affects populations already positioned at structural disadvantage, raising enduring questions about how democratic systems allocate punishment and distribute social risk.
Understanding how democratic systems normalize punitive expansion is therefore essential to any serious effort at reform.
