Here, let’s have a look of this fancy waffle graph. Different colors here represent different continents. Around the circle, there are labels of different countries. This graph is showing the ratios of social media user numbers over total population. As you can see in the graph, the larger the shape, or, the wider the position, the greater the ratio. Some Asia-Pacific countries have very big ratios while other Asia-Pacific countries have small ratios.

### 2.2 Freedom of Press Second, as the first plot shows, there is some consistency between proportion of social network users and counties’ distribution. I used color scale to plot the freedom of press Index. As we could see, forexample, Canada have a high level of freedom of press as well as high social network users percentage.

There are some interesting findings about the relationship between age of Facebook users and the number of Facebook users.
4.1 MeetUp.com Findings
By analyzing MeetUp.com data, we have found the most popular topics by counting the number of users in each MeetUp category created in MeetUp.com. ‘New Technology’, ‘Art’, ‘Watching Movies’, ‘Wine’, ‘Photography’ are the Top 5 most popular topics people in MeetUp.com like to have activities on over time.
Interesting ! Do these topics vary across city ? As New Yorkers, we would like to know what are the top topics in New York. Therefore, we selected data from three different cities: New York, Chicago and San Francisco. We found that these three countries are sharing most of the top topics such as ‘Tech’,‘Career/Business’,‘Socializing’, but it seems that New Yorkers are lacking of passion on ‘Sports/Recreation’ and Chicago people are lacking of passion on ‘Spirituality’.

4.3 Twitter Findings
In Twitter self-descriptions, there are some words that female users use a lot and there are some words that male users use a lot. A Twitter Gender Identifier was designed for identifying genders through looking at users’ self-descriptions. The mechanism behind this Twitter Gender Identifier is shown in the wordcloud: when encountering these high-frequency words, the identifier is able to identify whether the user is a female or a male. By looking at the wordcloud, we can see that the most frequently used words by female users are beauty, mother, mum, happy, and queen, while the most frequently used words by male users are technology, business, director, producer, and football.
