I would also add to Mike's post that it is unlikely that the US population will grow in the straight line projection that is shown in that graph.
The birthrate in US has been falling for over a decade and that is likely to continue (same trend is shown in all developed countries).
The only reason the population has not shrunk is because people are living longer and immigration. However, the life expectancy is stabilizing so unless immigration expands greatly (unlikel) you will see the populartion growth starting to curve down in a decade or so.
Actually the original chart posted is low compared to the US Census Bureau projection of 363 million by 2030. See Table 1:
http://www.census.gov/population/www/projections/projectionsagesex.htmlThe Gates Foundation, John Hopkins and the University of Washington use this data, so I assume it is pretty good data.

Depends on your definition of slowing down. These guys (Chaired by Bishop DiMarzio of Brooklyn) suggest the following:
http://www.migrationpolicy.org/task_force/new_chapter_summary.pdf"The proposed system would initially set annual immigration levels at about
1.5 million, approximately 300,000 less than the actual annual number of
immigrants — legal and illegal — being absorbed into the labor market and the
country today. The system would simplify many visa categories and procedures,
so that US immigration is better able to meet family unification and labor market
goals. Special visa categories would be created, such as “strategic growth visas”
for individuals in strategically important disciplines."
My Uncle did some of the Ford Foundation's controversial population studies back in the 70's and 80's. The Ford Foundation's focus was mainly on developing countries back then, but then they noticed that the subway was geting crowded on their way to work on 44th Street.
Now if anyone has any information about the rumored link between the Ford Foundation and the CIA back then, I am all ears because some of my Uncle Willie stories would make Tom Paul's relatives sound quite normal!
