Around the World in 80 Ways offers a (sometimes opinionated) discussion of 80 data-driven maps of our planet. Taken together, the maps tell a story about the physical world; about the impact our species is having on the world; and about how people live in the world - or at least how we lived immediately before the emergence of Covid-19.The maps lie. All maps lie. But the origins of the deceptions are explained, the data sources are signposted and referenced, and the readers are shown how to create their own maps using freely available software. The reader is thus armed with the tools needed to explore local, national or world data - on topics ranging from science to society; environment to entertainment; wealth to wellbeing - a valuable skill in an age when certain politicians are happy to refer to "alternative facts" and media outlets deliver data visualizations that sometimes mislead as much as inform.
