Please suppose I want to use Segi's standard population to calculate ASIR for childhood cancer. As you know, the calculation of ASIR is based on the special formula:

Sum( ( Segi's weight * Age-specific)/100,000), for each age group),

in Which the value of 100,000 is the sum of Segi's weights. However, in childhood cancer, we use the age of 0-14 or 0-19 years. In this case, does the denominator of the ASR formula change? Or remain the same 100,000.
