    Wife: “Why are you being weird about adding me on Facebook?”

    Husband: “BOYS ONLY!”

    I need to know, what is the scale? Is the middle that they are as common as same sex friendships and blue places same sex friendships are rare, or or is the blue end equal and everything else worse?

      Hey this is an info graphic, not actual data to make informed decisions on…

      But I assume that the middle of the scale is equally likely (50/50 same sex, mixed sex); and the ends are heavily skewed at like (90/10).

        The referenced paper isn’t on SciHub, but I found bits and pieces of it. E.g. here is a description of the ranking:

        In places where men and women form equal shares of their ties with women, the value of the CGFR is 1.

        Just before that section (right hand side of first page) there is a desription of how they calculate it.

        This page has many other countries not in the above graph, but it seems is only the appendices not the actual paper. There are versions for the top 10, 25, or 200 friends.

        There are hundreds of graphs in there using different scales, but this one uses their CGFR scale (top 200 friends): map of Australia and New Zealand with coloured regions showing light greens and pale reds, reasonably uniform except for a block in mid-western Australia that shows a darker blue colour roughly aligned with 0.75 on the 0 to 1 scale, and another section towards the western coast, representing a higher proportion of men/woman friendships on facebook for these sections. The rest of Australia and New Zealand are relatively consistent around the 0.4  to 0.6 range

        But anyway, it seems dark blue is roughly equal male/female to same gender friendships. The graphs I link are very similar to the one you posted, but I do notice the blue end is darker in yours. For example, the Africa map has the South Africa end at about 0.6 or 0.7:

        map of Africa showing red at the top (in the 0.1 to 0.2 range, gradually changing to a green/blue colour at the bottom, perhaps around the 0.65 to 0.75 range)

        It’s like someone took the map but made the scale slightly different, or perhaps that happened when loading data into that “india in pixels” map site that is referenced on your image.

        So it seems that everywhere in the world, same sex friendships are more common. It’s worth noting they used an algorithm to rank people’s friendship strength then took the top X friends (it appears the OP image is top 200).

      Well, I’ve converted a lot of internet relationship into lifelong IRL relationships. It all depends on what circle you’re running on.

      It’s facebook, I don’t really use facebook but most people I’m friends with are friends IRL and I presume this the case for most people who still use facebook.

          Sure, if I talked about my “facebook friend” then it would be referring to someone I only know on facebook, but that doesn’t mean it’s the only type of friendship on facebook. It would be like talking about a “work friend” or a “school friend”, it refers to how you met. The image doesn’t refer to “facebook friends”, it refers to men-women relationships on facebook.

              It’s about the ratio. If it were random, you’d expect men to be friends with roughly equal numbers of male and female friends (it’s not clear how NBs fit in).

              In reality, men are more likely to be friends with men and women are more likely to be friends with women. This is what the image is showing. Blue areas it’s more equal, red areas people are almost exclusively only friends with the same sex.

              The methodology didn’t only look at who people were friends with, but also looked at how friendly they were (using some facebook proprietary model). So they basically ranked people by how close their friendship was, and took the top 200 friends.

              So if you have 500 male friends and 500 female friends, but you only ever chat with your male friends and like your male friends posts, then it would likely rank you as having mostly male friends.

              I linked some details of the study in another comment.
