Reconcile early age groups for births.
dd_firstages_compute_births(data)The data to be harmonized
A dataset with early age groups reconciled e.g 0-14 becomes 10-14
In cases where for example 10_14 is missing and 0_14 is present, convert the latter to the former.
Another case is if 0-4 is missing and 0-1 and 1-4 are present, then sum both to get 0-4.
You can run getAnywhere(dd_firstages_compute_births) to view the definition of this function.
