Ranked: The World’s Most Surveilled Cities

This may come as a surprise, but it wasn’t until 2007 that the global urban population overtook the rural population. At that time, the two groups were split nearly 50/50, with around 3.3 billion people apiece.

Today, the percentage of people living in urban areas has grown to over 55%, and is expected to reach 68% by 2050. Due to this trend, many of the world’s largest cities have become home to tens of millions of people.

In response to such incredible density, governments, businesses, and households have installed countless security cameras for various purposes including crime protection. To grasp the scale of this surveillance, we’ve taken data from a recent report by Comparitech to visualize the most surveilled cities in the world.

The List (Excluding China)

Excluding China for the time being, these are the world’s 10 most surveilled cities.

CityPopulationNumber of CamerasCameras per
1,000 people
🇮🇳 Indore, India3.2M200,60063
🇮🇳 Hyderabad, India10.5M440,29942
🇮🇳 Delhi, India16.3M436,60027
🇮🇳 Chennai, India11.5M282,12625
🇸🇬 Singapore6.0M108,98118
🇷🇺 Moscow, Russia12.6M213,00017
🇮🇶 Baghdad, Iraq7.5M120,00016
🇬🇧 London, UK9.5M127,37313
🇷🇺 St. Petersburg, Russia5.5M70,00013
🇺🇸 Los Angeles, U.S.3.9M34,9599

Figures rounded

The top four cities all belong to India, which is the world’s second largest country by population. Surveillance cameras are playing a major role in the country’s efforts to reduce crimes against women.

Further down the list are cities from a variety of countries. One of these is Russia, which has expanded its use of surveillance cameras in recent years. Given the country’s track record of human rights violations, activists are worried that facial recognition technology could become a tool of oppression.

The only U.S. city on the list is Los Angeles, which contains some of the country’s wealthiest neighborhoods and municipalities. That includes Beverly Hills, which according to the Los Angeles Times, has over 2,000 cameras for its population of 32,500. That translates to about 62 cameras per 1,000 people, meaning that Beverly Hills would finish at #2 in the global ranking if it were listed as a separate entity.

Surveillance in China

IHS Markit estimates that as of 2021, there are over 1 billion surveillance cameras installed worldwide. The firm also believes that 54% of these cameras are located in China.

Because of limited transparency, it’s impossible to pinpoint how many cameras are actually in each Chinese city. However, if we assume that China has 540 million cameras and divide that amongst its population of 1.46 billion, we can reasonably say that there are 373 cameras per 1,000 people (figures rounded).

Cameras in China

A limitation of this approach is that it assumes everyone in China lives in a city, which is far from reality. The most recent World Bank figures suggest that 37% of China’s population is rural, which equates to over 500 million people.

With this in mind, the number of cameras per 1,000 people in a Tier 1+ Chinese city (e.g. Shanghai) is likely far greater than 373.

More About China

China’s expansive use of cameras and facial recognition technology has been widely documented in the media. These networks enable the country’s social credit program, which gives local governments an unprecedented amount of oversight over its citizens.

For example, China’s camera networks can be used to verify ATM withdrawals, permit access into homes, and even publicly shame people for minor offences like jaywalking.

This might sound like a dystopian nightmare to Western audiences, but according to Chinese citizens, it’s mostly a good thing. In a 2018 survey of 2,209 citizens, 80% of respondents approved of social credit systems.

*Inflation rates based on the latest available data.

As price pressures mount, 33 central banks tracked by the Bank of International Settlements (out of a total of 38) have raised interest rates this year. These coordinated rate hikes are the largest in two decades, representing an end to an era of rock-bottom interest rates.

Going into 2023, central banks could continue this shift towards hawkish policies as inflation remains aggressively high.

The Role of Energy Prices

Driven by the war in Ukraine, energy inflation is pushing up the cost of living around the world.

Since October 2020, an index of global energy prices—made up of crude oil, natural gas, coal, and propane—has increased drastically.

Double-Digit Inflation

Compared to the 2021 average, natural gas prices in Europe are up sixfold. Real European household electricity prices are up 78% and gas prices have climbed even more, at 144% compared to 20-year averages.

Amid global competition for liquefied natural gas supplies, price pressures are likely to stay high, even though they have fallen recently. Other harmful consequences of the energy shock include price volatility, economic strain, and energy shortages.

“The world is in the midst of the first truly global energy crisis, with impacts that will be felt for years to come”.

-Fatih Birol, executive director of the IEA

Double-Digit Inflation: Will it Last?

If history is an example, taming rising prices could take at least a few years yet.

Take the sky-high inflation of the 1980s. Italy, which managed to combat inflation faster than most countries, brought down inflation from 22% in 1980 to 4% in 1986.

If global inflation rates, which hover around 9.8% in 2022, were to follow this course, it would take at least until 2025 for levels to reach the 2% target.

It’s worth noting that inflation was also highly volatile over this decade. Consider how inflation fell across much of the rich world by 1981 but shot up again in 1987 amid higher energy prices. Federal Reserve chair Jerome Powell spoke to the volatility of inflation at their November meeting, indicating that high inflation has a chance of following a period of low inflation.

While the Federal Reserve projects U.S. inflation to fall closer to its 2% target by 2024, the road ahead could still get a lot bumpier between now and then.

Visualized: The Many Shapes of Bacteria

We introduce the visual diversity of bacteria and illustrate how they are categorized by appearance—from a single cell to an entire colony.

Invisible Diversity: The Many Shapes of Bacteria

Bacteria are amazing.

They were the first form of life to appear on Earth almost 3.8 billion years ago.

They make up the second most abundant lifeform, only outweighed by plants.

And most interesting of all: they exist in practically every environment on our planet, including areas where no other lifeforms can survive. As a result, bacteria exhibit a wide variety of appearances, behaviors, and applications similar to the lifeforms we see in our everyday lives.

The incredible diversity of bacteria goes underappreciated simply because they are invisible to the naked eye. Here, we illustrate how researchers classify these creatures on the basis of appearance, giving you a glimpse into this microscopic world.

A Life of Culture

Though bacteria may look similar to other microorganisms like fungi or plankton, they are entirely unique on a microscopic and genetic level.

Bacteria make up one of the three main domains of life. All life shares its earliest ancestor with this group of microbes, alongside two other domains: the Archaea and the Eukarya.

Archaea are very similar to bacteria, but have different contents making up their cell walls.

Eukarya largely consists of complex, multicellular life, like fungi, plants, and animals. Bacteria are similar to its single-celled members because all bacteria are also unicellular. However, while all Eukarya have nuclear membranes that store genetic material, bacteria do not.

Bacteria have their genetic material free-floating within their cellular bodies. This impacts how their genes are encoded, how proteins are synthesized, and how they reproduce. For example, bacteria do not reproduce sexually. Instead, they reproduce on their own.

Bacteria undergo a process called binary fission, where any one cell divides into two identical cells, and so on. Fission occurs quickly. In minutes, populations can double rapidly, eventually forming a community of genetically identical microbes called a colony.

Colonies can be visible to the human eye and can take on a variety of different shapes, textures, sizes, colors, and behaviors. You might be familiar with some of these:

Superstars of a Tiny World

The following are some interesting bacterial species, some of which you may be familiar with:

Epulopiscium spp

This species is unusually large, ranging from 200-700 micrometers in length. They are also incredible picky, living only within the guts of sturgeon, a type of large fish.

Deinococcus radiodurans

D. radiodurans is a coccus-shaped species that can withstand 1,500 times the dose of radiation that a human can.

Escherichia coli

Despite being known famously for poisoning food and agriculture spaces from time to time, not all E.coli species are dangerous.

Desulforudis audaxviator

Down in the depths of a South African gold mine, this species thrives without oxygen, sunlight, or friends—it is the only living species in its ecosystem. It survives eating minerals in the surrounding rock.

Helicobacter pylori

Known for causing stomach ulcers, this spiral-shaped species has also been associated with many cancers that impact the lymphoid tissue.

Planococcus halocryophillus

Most living things cease to survive in cold temperatures, but P. halocryophillus thrives in permafrost in the High Arctic where temperatures can drop below -25°C/-12°F.

‘Bact’ to the Future

Despite their microscopic size, the contributions bacteria make to our daily lives are enormous. Researchers everyday are using them to study new environments, create new drug therapies, and even build new materials.

Scientists can profile the diversity of species living in a habitat by extracting DNA from an environmental sample. Known as metagenomics, this field of genetics commonly studies bacterial populations.

In oxygen-free habitats, bacteria continuously find alternative sources of energy. Some have even evolved to eat plastic or metal that have been discarded in the ocean.

The healthcare industry uses bacteria to help create antibiotics, vaccines, and other metabolic products. They also play a major role in a new line of self-building materials, which include “self-healing” concrete and “living bricks”.

Those are just a few of the many examples in which bacteria impact our daily lives. Although they are invisible, without them, our world would undoubtedly look like a much different place.
