The Boylands is the only place mentioned in the image. The existance of the Boylands seem to imply that there is some kind of segregation in place. The mentions of scavenging makes one believe that this is a post-apocalytic wasteland. The nature of the apocalypse that caused the Boylands to exist is unknown.
The mention of a working microwave being a valuable resource indicates that the apocalyse resulted in the inhability to create or a great difficulty to obtain working electronics. Nevertheless, it seems that they maintain some level of normalcy as microwaves are still regarded as useful. This also implies that at least some sections of the population have access to the needed electricity to employ such appliance.
