Ontario School Enrolment Counts By Gender And Board

Ontario's Ministry of Education provides student enrolment figures for elementary and secondary schools, aggregated by gender and school board. Data is collected via the Ontario School Information System (OnSIS) October submissions and includes public and Catholic school types. The dataset was last updated in March 2026.

Use Cases

• Analyze gender balance trends across school boards using board_name, elementary_male_enrolment, and elementary_female_enrolment columns.
• Compare total enrollment capacity between elementary and secondary levels using total_male_enrolment and total_female_enrolment aggregated by board.
• Identify school boards with significant enrollment disparities by calculating ratios from secondary_male_enrolment and secondary_female_enrolment fields.
• Track historical changes in public versus Catholic school enrollment by joining datasets using board_number as a key.

Strengths

• Data covers two major school types in Ontario: public and Catholic.
• Includes specific enrolment counts for elementary and secondary levels, split by gender.
• Uses privacy protection by suppressing counts below 10 students.

Limitations

• Enrolment numbers from 2018-2019 onward are rounded to the nearest five, reducing precision.
• Rounded totals may not sum exactly due to post-calculation rounding methodology.
• Limited to Ontario province, not representative of other Canadian regions.
