demoscapes.org is a visual atlas of demographic surfaces hosted at @mpidr.bsky.social. It is also my passion project growing out of my 2016 human mortality database explorer. Did you publish something containing Lexis surfaces? Consider reaching out and having your work featured on the site.

Check out @jschoeley.com's very cool project: Demoscapes! It now features interactive Lexis surfaces based on our recent PNAS paper tracking cohort trends in major causes of death in the US. It's (to us data lovers) so fun! demoscapes.org/collections/...

Cool tool! What is the cause of this hill that I marked? I saw it in many, but not all countries. Smoking? Surviving a WW?

The left flank of the hill is male cohorts picking up smoking when they were young and then dying as a result later. The right flank of the hill is women catching up with men in their smoking behavior, balancing the sex ratio of mortality.
