Why net enrollment rate is lower than gross enrollment rate?

The net enrollment rate is lower than the gross enrollment rate because the former accounts only for the students who are of the official age for a specific educational level, while the latter includes all students enrolled, regardless of age. This means that gross enrollment can include older or younger students who do not fit the typical age range, resulting in a higher percentage. Additionally, net enrollment may exclude students who are over-age or under-age for their grade level, leading to a lower overall rate.
