I found and interesting website with GDPs for countries and the EU. I thought they were pretty cool. There are tons of other statistics on the website.

The U.S. and EU are pretty close. They're only $16 billion apart.

$160 billion u mean, that may sound abit more impressive.

im surprised at china's GDP, sure i know it was very big and expanding rapidly, but it looks like they may catch up with the US sooner than a period of years, if their environmental issues don't hold them back

Yes I did mean $160 billion, sorry about that.

I was also amazed at China's GDP. I forgot to include that I was shocked by how high their GDP is (I was tired).

China is probably the fastest growing economy in the world.

China's GDP doesn't really impress me. Their population is about 4 times that of the United States. I think a better measure of wealth would be GDP per capita which would show China being much lower.

Looking at your numbers, China holds more than 1/6 of the worlds population but is responsible for less than 1/6 of the world's GDP. This makes them below average on per person terms. Nothing to be worried about.

I will admit they've made significant progress though.
