A study commissioned by tech website Mashable has found that in the US and Australia, far more men than women have been verified, likely disproportionate to the gender of users.
Circle, square, and hexagonal nodes represent female, male, and unknown gender of users, respectively.
Designers and developers may be missing out on a huge opportunity by overlooking the gender of users when creating products.
Sometrics will tell you page views and unique visits, installs and uninstalls, age of users, gender of users, number of friends and location of users.
If additional data, such as year of birth or gender of users would be available - which is common in most datasets - it would be possible to identify very large fractions of the network.
The latter part is what the company started out with, by giving social app developers a way get an overview of the number of page views and unique visits, installs and uninstalls, age of users, gender of users, number of friends, location of users and more for their Facebook and MySpace apps.
The gender of users and non-users was similar (χ2 = 0.15, df 1, p = 0.696) as were the average ages of users and non-users (respectively mean = 38.0 years and 36.8 years; t = 0.78, df 126, p = 0.44).
However, impostors who know their closest person in the database or the genders of the users can be a threat to gait-based authentication.
However, by analyzing the gender ratios of users with a given degree (Figure 8) we find that users with a low (<100) or high (>300) number of friends are slightly more often women.
Non-probability sampling meant that we recruited several thousand volunteers within a couple of days, although it led to a bias in the age and gender distribution of users.
Institutions will be identified using existing records and registers in each country and recruited to provide a range of institutions that vary in: the proportion of voluntary (non-detained) and involuntary (detained) service users; size; geographic location (urban/rural); funding (statutory/non-statutory); gender of service users.
