Using the CDC's stats, a +10% change in deaths and a -10% change in births swings the US from +200k/year population growth to -513k/year.
Without lowering the birth rates, it's -146k/year.
These figures do not, of course, account for immigration, which would temporarily mask the declining population as long as enough people are able and willing to immigrate.
