Subject: Exactly what causes Inflation?

 I know the defination of inflation. It's basically surplus money chasing 
the available goods and services. But it seems to me that the rate of 
inflation is affectived by a continuing increase in populations. Also why 
is the rate of inflation very low in the US & quite high in other 
countrys? Is inflation affected by the money supply or is the money supply 
a constant ? Is there a correlation between a country's rate of population 
increase and its rate of inflation ?
