> In 2019 the American population increased from 327.2 to 238.2.

That's...not an increase.

> In 2019 1.03million immigrants were granted permanent resident status.

That's kind of a non-sequitur. To make your case, you’d need net migration numbers, not number of immigrants granted permanent residency.

> The fertility rate is 1.73.

It’s actually 1.6375, but fertility below replacement isn't negative natural growth, though sustained over the long term with steady-state life expectancy it eventually leads to it.
