The data from Brazil seems corrupt

Open patrickbryant1 opened this issue 3 years ago • 3 comments

If one looks at the data from November on across all the distrito federals of Brazil one can see that it is identical when normalizing by population. This is not possible, which means that the data has been calculated by multiplying the total cases in Brazil by the population shares in each distrito federal. I would like to add a pic here, but it is not possible and maybe you should look at it yourselves anyway.

Hi @patrickbryant1

Thanks a lot for raising this. The case numbers for all Brazilian states do indeed seem to be a constant proportion of the total number of cases for all dates in November. We source our case data from an external database, so we're not certain right now what might be causing the issue. We'll look into this and update this thread once we have an answer!

Hi @patrickbryant1

We've reviewed the case numbers more thoroughly. For the month of November, we don't seem to observe a very close tracking of population proportions and case proportions for the states. Perhaps we've misundersood your question? It should be possible to add a screenshot here -- if you could do that, it'd help us flesh this out better!

Hi, I find the relationship odd. When normalising by population, the curves seem to coincide. I pulled this data yesterday, have you changed it since? image

Normalized by 100'000 population image
