Skype users share data about themselves in their profiles. SR Consulting sampled 3.9 million profiles for statistics about age, country and gender. Some of their data from October suggests these findings.

Skypers are 30 years old, give or take.

• Average age: 29.7 years
• Mode: 25 years (most common age)
• Percent of users 40 years old and Younger: 80%
• The average age of Skype users within countries ranges from 19 in Lithuania and Bulgaria to 40 in Ecuador.

Some people don't share their age due to perceived age discrimination (too young, too old) and a general sense of privacy.

Europe and Asia beat the Americas.

About 46% of Skypers are in Europe, but Brazil and China have the most Skype users of any country, each with 8.1% of the Skype population.

Men report their sex more than women.

SR Consulting collected sex data, but 52% of users declined to state. We already know that women often "Decline To State" to avoid problems (harassing phone calls, for example) so this data is not worth sharing, IMHO.

More about the survey

Sebastian Ruell, CEO, said "We comply 100% with the Skype EULA and that we do not collect or store personal data of any kind. We take the privacy of skype users very seriously and avoid data like the person's real name, phone numbers or anything else that could connect the data to an individual person."
