Asbestos is such a strong driver of mesothelioma that mesothelioma geography more or less mirrors asbestos exposure, as demonstrated by this analysis. For men, but not women, shipyards were a major exposure. Interestingly, or perhaps I should say tragically, the same pattern was evident in the first mortality atlas of the UK published about 30 years ago - asbestos casts a very long shadow. The pattern is less clear in women, because few women worked in the shipyards in those days. I think I read somewhere that female asbestos exposure came from the way gas masks were manufactured in the second world war - by women.
I'm not sure about maps. They certainly display data but it's less clear that they generate research hypotheses or answer research questions. Often they confirm what we already know - asbestos causes mesothelioma, so mesothelioma is common where asbestos was common. Poor health is driven by poor socio economic circumstances so the map shows a north/south divide in the UK. And so on.
On the other hand one picture is worth a thousand words so perhaps maps should be regarded as a tool for communication rather than analysis.
