# Will inflation rate be the same if we use different base year?

I saw this chart where CPI for 2003 is 1.84, for 2004, is 1.889. I dont know the base year because its not in the chart. But base year has to have CPI of 1.

If we instead use 2003 as base year, is the inflation rate during 2003-2004 period, going to be different?
