Too bad that some kind of source for the statistics was not included in the image or in the OP to verify the accuracy of the data. If the source was provided, we could look at why the Soviet Union was included without guessing at possible reasons. I can make pretty graphs and make up statistics and share them as if they were true, but it doesn't make them true. As it is, it's a nice pic to have, but I can't share it. Shame that the effort wasn't put into it by the creator who compiled the statistics in the first place to include the source for the statistics, or by the OP as they should have before they decided to share it unsourced and unverified and in /s/truthhurts no less...despite not being readily verifiable as being truthful. Saved it, but marked it as unverified with research needed.
