Do you know math?
How does density change the same “per 100,000” number? I mean common man.

Let me help you with the stats/math as this seems really hard for you to figure out.

More densely populated areas have higher cases due to population and spread. The death rate is higher in some of these populated areas due to the demographic of those affected within the case load. If you have a dense area populated with younger and non-vulnerable people the 100,000 cases yields less death.
You can have an area that tests 100,000 people and 25% test positive with a lower death rate because of the demographic of the 100,000....younger and healthy.

Larger populations yield more spread and more cases. The death rate is determined by the underlying demographic of the people in the population.

The flip-side.... You can have a low population area with a high number of elderly or vulnerable have a higher death rate because of the demographic of those affected with less cases and/or spread.
