9 Charts Shaping the Modern World: Visualizing 2026 Best Countries Data | Best Countries

The world is changing quickly. Rising geopolitical tensions are reordering global power and testing the resilience of democratic institutions. Multiple climate and ecological systems are approaching breaking points. Shifting demographics and wealth distributions are changing the geography of money and population. These data visualizations offer a snapshot of the forces shaping the world today.

In 2024, more people voted in national elections than at any point in human history. According to the V-Dem (a nonpartisan organization that monitors democracy across the globe), the election year resulted in an overwhelming shift toward autocracywith attributes like freedom of expression, clean elections and civil society participation declining in even established democracies. V-Dem’s liberal democracy tracker shows that 115 of 179 countries backslid in liberal democracy from 2016 to 2025.

While the steepest declines were in autocratic countries that experienced coups, executive power grabs or breakdowns in constitutional restraint – the return of military rule in Burkina Faso and Niger, the dismantling of the post-Arab Spring political settlement in Tunisia, concentration of executive power and security-first governance in El Salvador – we also saw democratic erosion in more established democracies. Since 2016, the liberal democracy score in the United States fell 0.3 points – the fifth-largest decline of any country in that span.

As geopolitical tension and organized violence intensified over the last decade, war became more fragmented. State conflicts have reached record levels, while armed groups, militias, gangs and transnational insurgencies are increasingly reshaping the geography of violence.

The map of political violence incidents per capita reveals highly localized conflict zones in places where sovereignty is contested or state authority is under direct pressure. In Belgorod Oblast on the contested Russia-Ukraine border, there were 877 political violence events per 100,000 residents from March 2025 to April 2026, the most of any region (referred to as world administrative divisions).

Other hotspots include the Donetsk Oblast in Ukraine, Haut-Mbomou and Vakaga in the Central African Republic and Bari in Somalia. Other high-conflict zones include the military junta in Myanmar, gang violence in coastal Ecuador and cartel violence in Sinaloa in Mexico.

Over the next three decades, shifting demographics will dramatically redistribute the world’s population centers. As older industrialized nations stagnate under the weight of low birth rates and Sub-Saharan Africa sees a youth boom, the ranking of the world’s largest countries will undergo profound realignment.

While India and China will remain the No. 1 and No. 2 largest countries by 2050, Nigeria is projected to displace the United States as the No. 3 largest country by 2043. Other major shifts include Tanzania – forecasted to rise from No. 21 in 2025 to No. 14 in 2050 – and Italy, which is forecast to fall from No. 25 to No. 35 over the same period.

Biodiversity loss is one of the clearest signs of mounting pressure on the natural world. As habitats are reshaped by warming temperatures, pollution, invasive species and expanding development, the species most vulnerable to extinction are becoming concentrated in a narrower set of ecological strongholds.

The map of threatened species shows the regions where biodiversity loss is most acute, with especially high concentrations across South and Southeast Asia, equatorial Africa, Madagascar, the tropical Andes, Central America, eastern Australia and island systems in the Indian and Pacific oceans.

In Indonesia, Malaysia and the broader Southeast Asian tropics, forest conversion for agriculture, timber, mining and infrastructure threatens orangutans, tigers, elephants, hornbills and thousands of less visible amphibians, reptiles and plants. In Madagascar, slash-and-burn agriculture, charcoal production and forest fragmentation are threatening rare lemurs, chameleons and plant species.

Deforestation, hunting pressure and expanding resource extraction threaten great apes, forest elephants and other rainforest species in equatorial Africa.

While carbon removal technology and geoengineering may someday play a role in curbing climate change, the immediate goal is reducing greenhouse gas emissions. The world’s largest economies play an outsized role in determining the global climate trajectory, with China and the United States together accounting for nearly half of global greenhouse gas emissions.

But high emissions are not an unavoidable consequence of high economic output. The chart shows that while GDP and greenhouse gas emissions generally rise together, some service-oriented countries are able to generate substantial wealth with comparatively lower emissions. Major countries with the highest GDP-to-emissions ratios include Switzerland, Sweden and Hong Kong.

As countries build roads, ports, factories, housing, power systems and urban corridors, those changes show up at night. Denser settlements and electrification mean more light, making nighttime light a global proxy for development. Looking at the change in nighttime light around the world over the past three decades highlights the regions where economic growth – or decline – is happening the fastest

The map shows that infrastructure growth has been especially pronounced across China, India, Southeast Asia, the Middle East, parts of North Africa, Mexico, Brazil and several fast-growing urban corridors in sub-Saharan Africa. China’s eastern and interior development belts stand out, reflecting decades of urbanization, industrial expansion and large-scale transport and energy investment. India shows broad gains around major metros and growth corridors, where population growth, electrification and manufacturing have expanded the nighttime footprint. Meanwhile, pockets of red show places where nighttime light intensity declined, often signaling destruction, depopulation or economic contraction due to war, displacement or industrial collapse.

Wealth inequality is one of the defining economic challenges of our era. While the common refrain that the “rich get richer and the poor get poorer” is true in a number of ways, a look at global wealth distribution across four key percentile groups tells a more nuanced story.

While the share of wealth held by the top 1% has remained relatively level since 2000, the past several decades saw the most pronounced growth at even higher levels of wealth. Fueled by favorable tax policies, exponentially compounding assets and the astronomical valuations of modern technology monopolies, the share of wealth held by the top 0.01% surged from 6.4% in 1980 to 11.5% in 2024. Meanwhile, the global “middle 40%” saw a modest increase from 20.0% to 22.3% of global wealth share, driven by massive economic growth in emerging markets like China and India that lifted hundreds of millions out of poverty into the global middle class.

The global demographic landscape is undergoing a profound transition, shifting from an era of consistent growth to one of fragmented peaking and decline. The table of population peaks reveals stark regional divergences in growth, driven by collapsing fertility rates and rapidly aging societies.

While India is projected to continue to grow until peaking around 2063, economic giants like China have already passed their population peak, peaking in 2021 and forecast to experience sharp declines through 2100. The uneven growth is expected to reshape global labor markets, strain the finances of traditional social safety nets and redefine the geopolitical balance of power in the coming decades.

Radar charts for the 12 largest countries in the 2026 Best Countries ranking shows how difficult balance across the eight categories of national well-being can be to achieve at scale. Japan ranks No. 2 in Civic Health and No. 5 in Health, but No. 82 in Natural Environment. China ranks No. 17 in Economic Development but No. 94 in Natural Environment and No. 69 in Civic Health. The United States ranks No. 1 in Culture & Tourism and No. 2 in Economic Development, but No. 72 in Natural Environment and No. 41 in Civic Health.

In a framework that reflects the competing demands of modern statehood, few large countries manage to achieve broad success.
