When running the Impact function, we get a result of People affected 1,608,772 and People needing evacuation 16,000* Evacuation count rounded to nearest 1000.

I and Trevor would like to see that "People affected" should also be rounded to the nearest 1000.

Hi @vanpuk
I just want to confirm something:

  • by rounded to the nearest 1000, if it is 1.999.000 will be rounded to 2.000.000 and for 1.000.001 will be rounded to 1.000.000 ?
  • the people needing evacuation is calculated from the exact number of people affected or from the rounded number of people affected?

Hi @ismailsunni
Great questions -

  • what ever Ole has already set up - re evacuated rounding
  • use the affected rounded to calculate evacuation % - this will enable a consistent result (something you can do in your head to confirm)
