Sorry for all the questions, but can someone confirm how an annualised indicator is calculated. In the manual it states that an annualisation factor is applied e.g. a factor of 12 to the numerator when the denominator is a yearly population figure. My question is does this hold true for all numerators and denominators e.g. if the numerator is daily and the denominator weekly, will factors of 365 and 52 be applied respectively?
Thanks in advance...

Hi Dan
Yes it will take the period type of the aggregation period into account. The annualization factor is defined as
365 / number-of-days-in-aggregation-period
So if you have weekly data in the numerator and yearly data in the denominator for an annualized indicator, then the result is multiplied with an annualization factor equal to
365 / 7 = 52,2
Note that annualization only applies to indicators with yearly data in the denominator, as suggested in the name…
