Implementation of the SNVS began in 2000 and became fully functional nationwide in 2005.
These age groups represent aggregate data from the SNVS that better match groups of persons at different school grades or different stages of life.
Data are not fully representative, mainly because only 7% of the data reported to the SNVS come from private hospitals, clinics, and providers (22).
