Is Your Favorite Website Spying On You?
We previously showed the various ways that Google is tracking your online activity, as well as the data the search giant likely has stored about you.
But, it’s not just Google that is quantifying everything you do – pretty much every website is tracking you in some shape or form. Here’s what you need to know, and also a way to keep the trackers at bay.
Is Your Favorite Website Spying On You?
Today’s infographic is from StudyWeb, and it goes over how different websites engage in tracking users.
These trackers are intended to allow websites to tailor their experience to each user. This way, you’ll see more relevant ads, and your individual preferences will be remembered. While many people appreciate these benefits, others do not believe the trade-off with their privacy is worth it.
If you are a privacy-oriented person and want to take action, the bottom of the infographic gives you step-by-step instructions on how to change your browser preferences on a number of devices to avoid such extensive tracking.
How you experience the web should be your choice. That’s why being informed about how tracking works and learning how to protect your privacy are both important things to know.
While it’s true that trackers can’t be eliminated completely – mainly because top websites like Google and Amazon have their own proprietary tracking systems – taking these actions can at least help keep them at bay.

Ranked: The World’s Most Surveilled Cities
The world’s most surveilled cities contain hundreds of thousands of cameras. View this infographic to see the data in perspective.

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.
