* Location: Fight rates differ significantly between schools in different neighborhoods, states, and countries. Schools in high-poverty areas or those with high rates of social unrest tend to see more fights.
* School size: Larger schools naturally have a higher potential for incidents than smaller ones.
* School policies and enforcement: Strong anti-bullying programs and consistent disciplinary actions can significantly reduce the number of fights.
* Time of year: Certain times of the year might see an increase in conflict.
* Data collection methods: Accurate data is difficult to collect because many fights go unreported.
While some studies might offer statistics for specific locations or school districts, a global or even national average would be unreliable and potentially misleading.
