U.S. population is presently reducing at a rate of 9000 people per week or 468,000 per year. This is likely happening to other countries as well at different rates

 Our present average of deaths per week since February 28th of Coronavirus would take us to 490,256 tested deaths within 52 weeks or one year. However, the rate of coronavirus deaths per week likely is going to go up a lot (but I'm not sure how much higher it will go as of now). Fauci says 100,000 new cases per day is where it likely will go to which would also mean 5000 deaths per day at some point if it goes that high.

But, even now at the present rates population in the U.S. is already reducing by 9000 people per day if you add in the deaths from all causes (including natural deaths and then include all births and all deaths from coronavirus. I also included non-tested deaths to get the 9000 per day reduction of U.S. population by the way.

It will be much much worse in places like Brazil (maybe 12 to 16 times worse) and other 3rd world countries worldwide.

Then if you add starvation caused by interrupted food supply chains we are now looking at significant population reductions worldwide at this point for the next 5 to 10 years or until a vaccine is developed and deployed. And even then most of the world won't accept the vaccine because they will not trust it. And they could be right or wrong to think this.

So, the population of the U.S. under the present averages is reducing at the rate of 468,000 people per year at present averages. But, this is likely to get much worse by September.
