Hi Mark,

Just to add one more thing to what Jason wrote.

Typically the population data sets are yearly, while the numerator data is
most likely monthly or quarterly.

To be able to do data analysis on coverage rates within the normal 0-100%
range the indicators have a property called annualized.
If you set annualized to 'Yes' for an indicator then a relative
annualization factor will be added to the indicator calcuation each time a
new value is calculated.

Let's say you have an indicator "BCG coverage <1 year (%)" with a numerator
"BCG doses administered <1 year" (collected monthly) and denominator
"Population <1 year" (collected yearly), and an indicator type '%' with
factor=100.

The calculation of the monthly indicator value for "BCG coverage <1 year
(%)" would be 100 x 12 x (BCG doses administered <1 y / Population < 1
year).

The quarterly indicator calculation would be 100 x 4 x (BCG doses
administered / Population < 1 year) etc.
