[This postal service was co-posted at TechCrunch on iii/xvi/2010: http://techcrunch.com/2010/03/16/chatroulette-stats-male-perverts/]

Information technology'southward no surprise that Chatroulette is the latest media darling. It has all the elements of a good story: technology, mystery, celebrity and sex. If you oasis't heard of Chatroulette, this Daily Evidence segment is a skilful primer.

We were itching to study Chatroulette in a RJMetrics Dashboard, but no one seemed to accept any good information for u.s. to explore. So, we decided compile the data ourselves past leveraging Chatroulette Map, some scrappy programming, and a passionate tech community. We soon had detailed data on 2,883 Chatroulette sessions that tied users to geography, gender, appearance, and more.

Here are a few highlights from our findings:

• Nearly one-half of all Chatroulette spins connects you lot with someone from the U.s.. The next most probable state is France at fifteen%.
• Of the spins showing a single person, 89% were male and 11% were female person.
• Yous are more probable to encounter a webcam featuring no person at all than one featuring a solo female.
• 8% of spins showed multiple people backside the camera. 1 in 3 females appear equally part of such a group. That number is ane in 12 for males.
• i in 8 spins yield something R-rated (or worse)
• You are twice as likely to encounter a sign requesting female person nudity than you lot are to come across bodily female nudity

How We Did It

Thanks to RJMetrics, the assay was easy. Getting the data, however, was a bit of a challenge. The good news, withal, is that a roulette cycle is the statistician'southward best friend. The cardinal limit theorem tells united states of america that a large set up of random observations allows united states to draw high-confidence conclusions about the underlying data set.

We started our procedure at Chatroulette Map, an awesome new site that plots screenshots from random Chatroulette sessions on a map.

Chatroulette Map ties Chatters to Locations

It'south a petty-known fact that anyone you chat with on Chatroulette can decide your IP address using a program similar Wireshark. Chatroulette Map uses this IP data to geolocate and map random chatters on their website (along with nonetheless photos from their chats).

Chatroulette Map is likewise nice enough to expose all of its data points to anyone who clicks "View Source." Right in the raw source lawmaking of their homepage is the image URL, latitude, longitude, city, state, and state of every chatter on their map. As an added bonus, the file name of each image is a UNIX timestamp of when it was taken. Jackpot. (Note: nosotros tried contacting the creators of Chatroulette Map to participate in this story merely did not receive a response.)

Once we had photos, times, and locations, we needed data on what was happening in each chat photo. We coded up a quick webpage that displayed a random photo from the data set and asked some bones multiple-choice questions about that photo. These included questions on age, gender, and what the person in the photograph was doing. We coded up the backed so that a photograph wouldn't be taken out of rotation until 2 votes from different IP addresses provided an identical set of answers.

We posted the link to Hacker News on Sat night. In nether two hours, we received x,770 photo assessments from 1,012 distinct IP addresses. Every photo received a corroborated profile. We had our information.

Five minutes afterward, the data was loaded into a hosted dashboard on RJMetrics and returning the results you see below.

Caveats

Earlier we go to the data, nosotros should signal out the uncontrolled inputs that could be skewing these results:

• We know nothing about how Chatroulette matches up chatters, and we deed on the assumption that pairings are truly random.
• We know nil near the methodology used by Chatroulette Map. If they excluded data points for any reason or did not sample randomly, our assay could be skewed.
• Geolocation past IP accost is an imperfect science that is typically only accurate within a few dozen miles. It tin can also be thrown off past users taking advantage of proxy servers or using other techniques to disguise their IP addresses.
• Human epitome recognition is imperfect (even if mitigated past our vote convergence system). Any images that were judged incorrectly could skew the results.
• It's also important to notation that statistics about "the average chat session" (which we present here) are not the aforementioned equally stats virtually "the average user." For instance, imagine if female chats averaged 100 seconds each, but male chats averaged ten seconds each. Fifty-fifty if there were equal numbers of male and female users, males would enter the pool more than often and would therefore appear in front of y'all more than often, making the "average session" more than likely to contain a male person chat partner. Considering of this, all of our statistics are about the average session and not the average user.

The Results

Gender

Equally y'all might expect, you're most likely to encounter a solo male person in any given chat session. 72% of our chat sessions were with solo males. Interestingly, 11% showed no person at all while only 9% showed a solo female. So, if you're looking for women on Chatroulette, be forewarned: you lot're more than probable to encounter an empty chair.

Most Conversation Partners were Male

Likewise interesting is the prevalence of groups on Chatroulette. In all, 8% of chats featured a group of people (iv% all-male, 2% all-female, and 2% mixed). If you include groups, your adventure of encountering a female person grows to thirteen%. However, this means that if you exercise encounter a female, there is about a 1 in iii run a risk that she will exist part of a group. In contrast, the adventure a male will exist part of a group is just about one in 12.

Age

This assay excludes cams where historic period could not be estimated. As you lot might wait, most people were young adults (about 70%). Nigh 20% were nether 20 and about 10% were twoscore and older.

Most conversation partners are young adults

When we combine age with the gender statistics that we tracked above, nosotros acquire even more than. For example, females tended to exist younger than males, with 23% nether 20 (vs. 18% for males). Only 3% of females were over 40 (vs. 8% for males).

Groups of females were even younger. Female-only groups were "Teen or Younger" 65% of the time, while groups of males were "Teens or Younger" only 36% of the fourth dimension. There were no groups whatsoever of people 40 or older.

Location

47% of the Chatroulette participants measured were from the U.s.a.. The well-nigh pop countries are shown below:

Most chatters are from the United States

When we combine geography with gender and age, we acquire even more:

• Italy had the highest concentration of solo males at 98%. Information technology also had the highest concentration "Men over 40? at 13% (more than 3x the US rate of four%).
• The Usa has the highest concentration of groups at 13%, followed by The netherlands at 9%.
• Canada had the highest concentration of solo females at xiii%, followed past the US at 10%.

Perverts

If y'all've always used Chatroulette, you lot probably noticed that non everyone is there but to conversation. Some users, which we have affectionately labeled "perverts," fit into whatever of these three categories:

• Announced to not exist wearing any clothes whatsoever
• Are displaying explicit nudity
• Appear to be committing a lewd human action

The overall pervert charge per unit in Chatroulette is 13%. This means about ane in 8 chat sessions will have something decidedly Rated R (or NC-17) on the other stop. Of the perverts that were identified, only viii% were female person. Combined with the overall female person rate, that ways less than 1% of chats feature a female pervert.

Below, we come across the "debauchee rate" by country:

Chatroulette debauchee concentration is the highest in the UK

The Great britain dominates the rankings here with a pervert concentration of 22%! Turkey, French republic, and Germany tie for 2nd place with rates of 15%. Bringing down the global average is the United States, which boasts the lowest pervert concentration of the bunch: 10%.

As well worth mentioning are the users who display signs (like the ane below) requesting female nudity.

Signs like this brand up between 1% and 2% of all chats. This ways that y'all're twice every bit probable to meet a sign requesting female nudity than y'all are to encounter actual female nudity.

Validation

In trolling through the thousands of photos collected past Chatroulette Map, I came across this extremely interesting epitome. It contains a statistical breakdown of what this user saw during his many Chatroulette chat sessions. Audio familiar?

These stats appear to be based on a data gear up of 1,090 points (pretty impressive for a single user). The numbers are by and large in the same ballpark every bit ours (although we observed a higher pervert charge per unit). We're not certain who was behind this, but we like their style– they managed to sum up the gist of this blog mail service in a single epitome.

Conclusion

Scarcity of the information made this projection both challenging and exciting. In an ideal world, information technology would be great to analyze things like average session length based on different attributes, conversation user return rates, cohort analysis, and more than. Because of the mostly-anonymous nature of Chatroulette, that information volition exist difficult to come by. For now, at least y'all have a improve idea of what you will run into when yous hit that Side by side button.
