The World’s 15,000 Nuclear Weapons: Who Has What?

Published

on

Between North Korea’s constant nuclear test provocations and the recent “fire and fury” comments by President Trump, concerns about nuclear conflict are re-ignited around the world.

So, how many nuclear weapons are there, and what exactly is happening right now? Let’s launch into it.

Who has Access to Nuclear Weapons?

Nuclear Weapons Factsheet

As the map above demonstrates, the United States and Russia still maintain the world’s largest stockpiles of nuclear weapons, holding 92% of the world’s estimated 15,000 nuclear warheads.

While today’s arsenals seem quite excessive, they are actually quite modest compared to historical totals such as those during the Cold War. In 1986, for example, there were actually 70,300 nuclear weapons globally – but luckily for us, the number of warheads has eased down over time as countries disarm more weapons.

Will this number of warheads continue to slide down as a result of increased international cooperation? The Brookings Institution has grouped the nine countries with nuclear arsenals into categories that identify prospective entrants to the global arms control regime:

Any advancement of multilateral arms control, such as a treaty limiting limiting nuclear weapons, would likely take place between these countries.

Mapping Nuclear Sites Within the United States

Thanks to various arms reduction agreements, thousands of nuclear warheads have been retired. That said, warheads are still stored in a number of sites around the continental United States. The map below also highlights laboratories and interstate shipping routes. (Yes, nuclear weapons are apparently shipped in big rigs.)

The Wild Card: North Korea

The Hermit Kingdom is a relatively minor player in the nuclear weapon ecosystem, but they have been capturing the world’s attention. Under Kim Jong Un, North Korea has dramatically ramped up the frequency of missile tests, with 17 confirmed launches so far in 2017.

Here’s a look at the country’s arsenal of nuclear weapons, along with ranges of specific weapons.

North Korea Missile Range

More than a decade has passed since North Korea detonated its first nuclear weapon, and the country is now believed to be capable of intercontinental ballistic missile delivery. This, combined with aggressive rhetoric from North Korean leader, Kim Jong Un, has forced the Trump administration to take their threats more seriously.

Talking Heads Kim Jong Un

That said, experts suggest that recent provocations aren’t much different from previous periods of tension between the two countries, and that the risk of an actual conflict is overblown.

North Korea’s comments are clearly deterrent in nature, and the Guam ‘threat’ was exactly along those lines.

– David Kang, director, Korean Studies Institute, USC

Either way, while the prospect of an all-out war is unlikely – the war of words between North Korea and the United States is likely destined to continue.

Chart: 70 Years of China’s Economic Growth

View a high-resolution version of this graphic here.

From agrarian economy to global superpower in half a century—China’s transformation has been an economic success story unlike any other.

Today, China is the world’s second largest economy, making up 16% of $86 trillion global GDP in nominal terms. If you adjust numbers for purchasing power parity (PPP), the Chinese economy has already been the world’s largest since 2014.

The upward trajectory over the last 70 years has been filled with watershed moments, strategic directives, and shocking tragedies — and all of this can be traced back to the founding of the People’s Republic of China (PRC) on October 1st, 1949.

How the PRC Came to Be

The Chinese Civil War (1927–1949) between the Republic of China (ROC) and the Communist Party of China (CPC) caused a fractal split in the nation’s leadership. The CPC emerged victorious, and mainland China was established as the PRC.

Communist leader Mao Zedong set out a few chief goals for the PRC: to overhaul land ownership, to reduce social inequality, and to restore the economy after decades of war. The first State Planning Commission and China’s first 5-year plan were introduced to achieve these goals.

Today’s timely chart looks back on seven decades of notable events and policies that helped shape the country China has become. The base data draws from a graphic by Bert Hofman, the World Bank’s Country Director for China and other Asia-Pacific regions.

The Mao Era: 1949–1977

Mao Zedong’s tenure as Chairman of the PRC triggered sweeping changes for the country.

1953–1957: First 5-Year Plan
The program’s aim was to boost China’s industrialization. Steel production grew four-fold in four years, from 1.3 million tonnes to 5.2 million tonnes. Agricultural output also rose, but it couldn’t keep pace with industrial production.

1958–1962: Great Leap Forward
The campaign emphasized China’s agrarian-to-industrial transformation, via a communal farming system. However, the plan failed—causing an economic breakdown and the deaths of tens of millions in the Great Chinese Famine.

1959–1962: Lushan Conference and 7,000 Cadres meeting
Top leaders in the Chinese Communist Party (CCP) met to create detailed policy frameworks for the PRC’s future.

1966–1976: Great Proletarian Cultural Revolution
Mao Zedong attempted to regain power and support after the failures of the Great Leap Forward. However, this was another plan that backfired, causing millions more deaths by violence and again crippling the Chinese economy.

1971: Joined the United Nations
The PRC replaced the ROC (Taiwan) as a permanent member of the United Nations. This addition also made it one of only five members of the UN Security Council—including the UK, the U.S., France, and Russia.

1972: President Nixon’s visit
After 25 years of radio silence, Richard Nixon was the first sitting U.S. President to step foot into the PRC. This helped re-establish diplomatic relations between the two nations.

1976–1977: Mao Zedong Death, and “Two Whatevers”
After Mao Zedong’s passing, the interim government promised to “resolutely uphold whatever policy decisions Chairman Mao made, and unswervingly follow whatever instructions Chairman Mao gave.”

1979: “One-Child Policy”
The government enacted an aggressive birth-planning program to control the size of the country’s population, which it viewed as growing too fast.

A Wave of Socio-Economic Reforms: 1980-1999

From 1980 onward, China worked on opening up its markets to the outside world, and closing the inequality gap.

1980–1984: Special Economic Zones (SEZs) established
Several cities were designated SEZs, and provided with measures such as tax incentives to attract foreign investment. Today, the economies of cities like Shenzhen have grown to rival the GDPs of entire countries.

1981: National Household Responsibility System implemented
In the Mao era, quotas were set on how many goods farmers could produce, shifting the responsibility of profits to local managers instead. This rapidly increased the standard of living, and the quota system spread from agriculture into other sectors.

1989: Coastal Development Strategy
Post-Mao leadership saw the coastal region as the potential “catalyst” for the entire country’s modernization.

1989–1991: Post-Tiananmen retrenchment
Early 1980s economic reforms had mixed results, and the growing anxiety eventually culminated in a series of protests. After tanks rolled into Tiananmen Square in 1989, the government “retrenched” itself by initially attempting to roll back economic reforms and liberalization. The country’s annual growth plunged from 8.6% between 1979-1989 to 6.5% between 1989-1991.

1990–1991: Shanghai and Shenzhen stock exchanges open
Combined, the Shanghai (SSE) and Shenzhen (SZSE) stock exchanges are worth over $8.5 trillion in total market capitalization today.

1994: Shandong Huaneng lists on the NYSE
The power company was the first PRC enterprise to list on the NYSE. This added a new N-shares group to the existing Chinese capital market options of A-shares, B-shares, and H-shares.

1994–1996: National “8-7” Poverty Reduction Plan
China successfully lifted over 400 million poor people out of poverty between 1981 and 2002 through this endeavor.

1996: “Grasp the Large, Let Go of the Small”
Efforts were made to downsize the state sector. Policy makers were urged to maintain control over state-owned enterprises to “grasp the large”. Meanwhile, the central government was encouraged to relinquish control over smaller SOEs, or “let go of the small”.

1997: Urban Dibao (低保)
China’s social safety net went through restructuring from 1993, and became a nationwide program after strong success in Shanghai.

1997-1999: Hong Kong and Macao handover, Asian Financial Crisis
China was largely unscathed by the regional financial crisis, thanks to the RMB (¥) currency’s non-convertibility. Meanwhile, the PRC regained sovereignty of Hong Kong and Macau back from the UK and Portugal, respectively.

1999: Western Development Strategy
The “Open Up the West” program built out 6 provinces, 5 autonomous regions, and 1 municipality—each becoming integral to the Chinese economy.

Turn of the Century: 2000-present

China’s entry to the World Trade Organization, and the Qualified Foreign Institutional Investor (QFII) program – which let foreign investors participate in the PRC’s stock exchanges – contributed to the country’s economic growth.

2006: Medium-term Plan for Scientific Development
The PRC State Council’s 15-year plan outlines that 2.5% or more of national GDP should be devoted to research and development by 2020.

2008-2009: Global Financial Crisis
The PRC experienced only a mild economic slowdown during the crisis. The country’s GDP growth in 2007 was a staggering 14.2%, but this dropped to 9.7% and 9.5% respectively in the two years following.

2013: Belt and Road Initiative
China’s ambitious plans to develop road, rail, and sea routes across 152 countries is scheduled for completion by 2049—in time for the PRC’s 100th anniversary. More than $900 billion is budgeted for these infrastructure projects.

2015: Made in China 2025
The PRC refuses to be the world’s “factory” any longer. In response, it will invest nearly $300 billion to boost its manufacturing capabilities in high-tech fields like pharmaceuticals, aerospace, and robotics.

Despite the recent ongoing trade dispute with the U.S. and an increasingly aging population, the Chinese growth story seems destined to continue on.

China Paving the Way?

The 70th anniversary of the PRC offers a moment to reflect on the country’s journey from humble beginnings to a powerhouse on the world stage.

Because of China’s economic success, more and more countries see China as an example to emulate, a model of development that could mean moving from rags to riches within a generation.

Visualizing the Decline of Confidence in American Institutions

Americans rely on several institutions for their services and safety—but how has their confidence in institutions changed since 1975?

Published

on

Every day, the public relies on a number of major institutions for services and safety. From banks and governments, to media and the military—these institutions play an important role in shaping life as we know it.

Yet, today’s interactive data visualization from Overflow Data shows that America’s confidence in institutions has drastically waned. The data relies on the General Social Survey (GSS) to provide a 40-year overview of how sentiment has changed with respect to 13 different institutions.

Select an institution from the drop-down menu below to see how confidence has changed over time

The Erosion of Confidence

Overall, confidence in most institutions has eroded. Americans find it especially hard to trust their government: the “great deal of confidence” metrics for Congress, the Supreme Court, and the Executive Branch were low to begin with, and have declined further since 1975.

That said, the biggest overall drop belongs to the press, which saw 50% of surveyed Americans saying they have “hardly any confidence” in it in 2016. This is nearly a three-fold increase from 1975, when that number was just 19%. Of course, with the rise of fake news in more recent years, the erosion of confidence in media doesn’t seem to be slowing down.

Here’s a look at the two extremes of sentiment regarding the studied institutions, showing how the opposite measures of “hardly any confidence” and a “great deal of confidence” have changed since 1975:

InstitutionConfidence level19752016Change

⚖️ U.S. Supreme CourtHardly any19.2%17.4%-1.8 p.p.

Banks and financial institutions have also suffered a bad rep in the public eye. Their “great deal of confidence” metric has dropped sharply from 32.3% to 14.1% in four decades.

One major exception is the military, which emerges as the most trusted institution. Americans’ faith in the military has also shown the most improvement, with a 17.1 p.p increase in a “great deal of confidence” since 1975.

The Split Widens Further

While measuring public confidence in institutions can be subjective, it provides an understanding of where Americans want to see change and reform take place.
