Hi, I want to project population from an old census report.....the formula is as follows

population*(1+(growth rate/100))^16

I am trying this expression for calculating from attribute table but ITS NOT WORKING

[POP_B_SEX]*(1+ (4.33 / 100 ))Exp (16 )

Note : [POP_B_SEX] is the only column i am using from attribute table.

The formula works for me....

Go in ArcMap to the Geoprocessing menu and click Geoprocessing Results. What is the error message that the Field Calculator returns?

To make the formula more simple:

(1+ (4.33 / 100 ))^16 = 1.97037

Your formula can be rewritten as:

[POP_B_SEX]*1.97037
