This is so cool. This atlas has Lexis plots on how various things have changed over time in different age groups – mortality rates, fertility rates, number of parents and siblings. And you can reach out to Jonas to add your own plots too. I'd like to see Lexis plots for absolutely everything.

The last part abt how measles disrupts immunity vs other infections is, imo, underappreciated (& mechanism was recently clarified). It's part of why measles vaccination was seen to help beyond just reducing measles complications - not getting measles reduces severity of subsequent infections too.
