Hi,

Population in 2003 : 12.853

Population in 2004 : 13.290

Difference = 0.437

hi Hannibal lecter

Hi, this is a part of population grew

2004 13.290Difference is 1.34

not 0.34

To work out the percentage growth you need this formula:

% increase = (new value - old value)/old value x 100

new value - old value = 13.29 - 12.853 = 0.437

Please check your working here as you have an incorrect value.

so % increase = 0.437/12.853 x 100 = 3.3999984 which is about 3.4%
