Age distribution of secondary students in NSW government schools (2011-2023)

**Data Notes:**\r\n\r\n* Data is collected mid-year (census date: first Friday in August) from NSW government schools as per National Schools Statistics Collection (NSSC).\r\n\r\n* From 2020, students in mainstream support classes are reported by their underlying grade of enrolment. Previously, students in support classes in mainstream schools were not included.\r\n\r\n* Students in schools for specific purposes (SSPs) are not included.\r\n\r\n* Students in distance education and Intensive English Centres are included with their appropriate grade levels.\r\n\r\n* OC classes are not included in secondary students. IEC students are included.\r\n\r\n* In most scholastic years there are a small number of students in atypical age groups. For students under 18 years, these have been included in the nearest band. This is indicated with an asterisk. As a result, the sum of each row may not equal the totals reported. See relevant tables in Statistical Bulletin for more details.\r\n\r\n\r\n**Data Source:**\r\n\r\n* [Schools and Students: Statistical Bulletin](https://data.cese.nsw.gov.au/data/dataset/schools-and-students-statistical-bulletin).
