US Population to Hit 300 Tomorrow Morning

The BBC has an article saying the US population will hit 300 million tomorrow morning. Apparently we were 200M in 1967, and 100M in 1915.

Here's a graph of the population since 1900.

It would be interesting to collect such graphs for all countries, and map them against religion, GNP, surface area, etc. I'm sure someone has done it already.

I had expected the graph of the Swedish population to be flatter than this, but it actually is incredibly flat by comparison.
