International Gender Differences and Gaps in Online Social Networks

DESCRIPTION

Article 1 of the United Nations Charter claims “human rights” and “fundamental freedoms” “without distinction as to [...] sex”. Yet in 1995 the Human Development Report came to the sobering conclusion that “in no society do women enjoy the same opportunities as men”. Today, gender disparities remain a global issue and addressing them is a top priority for organizations such as the United Nations Population Fund. To track progress in this matter and to observe the effect of new policies, the World Economic Forum annually publishes its Global Gender Gap Report. This report is based on a number of offline variables such as the ratio of female-to-male earned income or the percentage of women in executive office over the last 50 years. In this paper, we use large amounts of network data from Google+ to study gender differences in 73 countries and to link online indicators of inequality to established offline indicators. We observe consistent global gender differences such as women having a higher fraction of reciprocated social links. Concerning the link to offline variables, we find that online inequality is strongly correlated to offline inequality, but that the directionality can be counter-intuitive. In particular, we observe women to have a higher online status, as defined by a variety of measures, compared to men in countries such as Pakistan or Egypt, which have one of the highest measured gender inequalities. Also surprisingly we find that countries with a larger fraction of within-gender social links, rather than across-gender, are countries with less gender inequality offline, going against an expectation of online gender segregation. On the other hand, looking at “differential assortativity”, we find that in countries with more offline gender inequality women have a stronger tendency for withing-gender linkage than men. We believe our findings contribute to ongoing research on using online data for development and prove the feasibility of developing an automated system to keep track of changing gender inequality around the globe. Having access to the social network information also opens up possibilities of studying the connection between online gender segregration and quantified offline gender inequality.

The Global GenderGap Report

Page 3: International Gender Differences and Gaps in Online Social Networks

Global Gender Gap Report● Introduced in 2006● Captures the magnitude

and scope of gender-based disparities and tracks their progress

● Designed to create awareness of the challenges posed by gender gaps

Page 4: International Gender Differences and Gaps in Online Social Networks

Global Gender Gap Index - Variables

● Social variables related to basic rights● Four categories (sub-indexes):

– Economy: wage, income, # managers, etc

– Education: literacy rate, educ. levels enrollment

– Health: births, life expectancy

– Politics: # seats in parliament, # ministers, etc

Page 5: International Gender Differences and Gaps in Online Social Networks

Global Gender Gap Index - Algorithm

1. Calculate the female by male ratio of the variables;

2. Truncate the ratios at a certain level;

3. Calculate sub-indexes for each category;

4. Calculate the average of the four sub-indexes to create the overall index.

Scores: 0.0 (total inequality)→ 1.0 (total equality)→

Google+

Page 7: International Gender Differences and Gaps in Online Social Networks

Google+ Dataset● Date: 1st semester of 2012● Extracted all IDs from

Google+'s sitemap– 193 million IDs

● Parsed profile and graph information

– 160 million profiles– 61 million nodes– 1 billion edges

Page 8: International Gender Differences and Gaps in Online Social Networks

Google+ User Information ● Country: last location from

the "Places lived" field.– 22 million users

● Gender: self-declared field.– 34.4% female– 63.8% male – 1.8% other

Page 9: International Gender Differences and Gaps in Online Social Networks

Google+ Variables - Network● In-degree: number of followers.

● Out-degree: number of friends.

● Reciprocity: fraction of reciprocal links.

● Clustering coefficient: probability of any two neighbors being neighbors.

● PageRank: relative importance of a user in the network.

Page 10: International Gender Differences and Gaps in Online Social Networks

Google+ Variables - Assortativity● Assortativity: fraction of links to the same gender.

– High value strong same-gender linkage, cross-gender links →are less likely to happen.

● Differential assortativity: "lift" of the fraction of users of the same gender followed by a particular user.– Example: computer science students (males linked to male)– High value the user is more likely than by random chance to →

follow other users of his/her same gender.

Online vs. Offline Gender Gaps

Page 17: International Gender Differences and Gaps in Online Social Networks

Gender Gap vs. # users

Countries with lower gender equality more →men than women online

Page 18: International Gender Differences and Gaps in Online Social Networks

Gender Gap vs. # followers

Countries with low offline equality women are, →surprisingly, followed more than men

Page 19: International Gender Differences and Gaps in Online Social Networks

Gender Gap vs. Assortativity

Countries with high gender equality →higher assortativity

Countries with low gender equality →women have higher assortativity

Countries with high gender equality →no difference between genders

Discussion

Page 21: International Gender Differences and Gaps in Online Social Networks

The Jackie Robinson Effect● Jackie Robinson: 1st African-

american baseball player to play in Major League Baseball (1947)

● Probably, only had the chance to play because he was really good

● Women who decided to go online in a country such as Pakistan are likely to be more self-confident and tech-savvy than random male counterparts

Page 22: International Gender Differences and Gaps in Online Social Networks

Online Stalking● “Stalking”: women attracting follow links from

men● In countries with low gender equality, this effect

might be stronger, so women have more followers than men

● In countries with low gender equality, women might shy away from cross-gender links, so female assortativity is higher than men

Conclusion

Page 24: International Gender Differences and Gaps in Online Social Networks

Concluding Remarks● Large-scale study of gender differences and

gender gaps around the world in Google+

● Online indicators can capture the offline gender gap trend among countries– # users positive correlation→

– # followers negative correlation→
