Ranked: The World’s Most Surveilled Cities
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.
City | Population | Number of Cameras | Cameras per 1,000 people |
---|---|---|---|
🇮🇳 Indore, India | 3.2M | 200,600 | 63 |
🇮🇳 Hyderabad, India | 10.5M | 440,299 | 42 |
🇮🇳 Delhi, India | 16.3M | 436,600 | 27 |
🇮🇳 Chennai, India | 11.5M | 282,126 | 25 |
🇸🇬 Singapore | 6.0M | 108,981 | 18 |
🇷🇺 Moscow, Russia | 12.6M | 213,000 | 17 |
🇮🇶 Baghdad, Iraq | 7.5M | 120,000 | 16 |
🇬🇧 London, UK | 9.5M | 127,373 | 13 |
🇷🇺 St. Petersburg, Russia | 5.5M | 70,000 | 13 |
🇺🇸 Los Angeles, U.S. | 3.9M | 34,959 | 9 |
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).
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.

Mapped: Population Growth by Region (1900-2050F)
In this visualization, we map the populations of major regions at three different points in time: 1900, 2000, and 2050 (forecasted).

In fewer than 50 years, the world population has doubled in size, jumping from 4 to 8 billion.
In this visualization, we map the populations of major regions at three different points in time: 1900, 2000, and 2050 (forecasted). Figures come from Our World in Data as of March 2023, using the United Nations medium-fertility scenario.
Population by Continent (1900-2050F)
Asia was the biggest driver of global population growth over the course of the 20th century. In fact, the continent’s population grew by 2.8 billion people from 1900 to 2000, compared to just 680 million from the second on our list, Africa.
Region | 1900 | 2000 | 2050F |
---|---|---|---|
Asia | 931,021,418 | 3,735,089,775 | 5,291,555,919 |
Africa | 138,752,199 | 818,952,374 | 2,485,135,689 |
Europe | 406,610,221 | 727,917,165 | 704,398,730 |
North America | 104,231,973 | 486,364,446 | 679,488,449 |
South America | 41,330,704 | 349,634,344 | 491,078,697 |
Oceania | 5,936,615 | 31,223,133 | 57,834,753 |
World 🌐 | 1,627,883,130 | 6,149,181,237 | 9,709,492,237 |
China was the main source of Asia’s population expansion, though its population growth has slowed in recent years. That’s why in 2023, India surpassed China to become the world’s most populous country.
Southeast Asian countries like the Philippines and Indonesia have also been big drivers of Asia’s population boom to this point.
The Future: Africa to Hit 2.5 Billion by 2050
Under the UN’s medium-fertility scenario (all countries converge at a birthrate of 1.85 children per woman by 2050), Africa will solidify its place as the world’s second most populous region.
Three countries—Nigeria, Ethiopia, and Egypt—will account for roughly 30% of that 2.5 billion population figure.
Meanwhile, both North America and South America are expected to see a slowdown in population growth, while Europe is the only region that will shrink by 2050.
A century ago, Europe’s population was close to 30% of the world total. Today, that figure stands at less than 10%.
