Yes, People Exist in Pyongyang
A common comment I've gotten on the fraction of photos/videos I've posted from North Korea (as I continue to sift through hundreds of them) is the lack of people on the streets. Bearing in mind that I haven't yet posted videos and photos from busy places like the metro/subway system and public places, I'm sharing these screenshots from a video of a busy public square near the train station, a square that was filled with people, mostly sitting, each time I passed it.
