Custom age distributions

🙋 Feature Request

We have had multiple requests for adjusting age distributions when local community doesn’t match the country.

🔦 Context

Since severity is heavily age dependent, the burden on the health care system depends strongly on the age distribution of the population.

💁 Possible Solution

Add a column to the severity table that is prepopulated with values of the country from a scenario but can be modified.

• add a column to the severity table
• once modified, the value of the age distribution drop down should go to custom
• currently, state contains a key for the age distribution which is read out in the runSimulation function. This should probably be replaced by the distribution proper (an array of 9 numbers)
• the URL should contain the values of the age distributions, rather than the country key
• update the description of the severity card to reflect these changes.

I worry about the asterisk, just because in principle you could modify the numbers to be substantially different from the initial condition, in which case the pointer is relatively meaningless. Personally I would vote for a simple change to “Custom” as a catch all state once you start fiddling with the numbers.

Longer term, it would make sense to allow users to import their “custom” scenarios with nice names but this is a seperate, longer term issue.

I’ve been tinkering with that in #293 but that is very much a work in progress.
