Bullying, 10th grade (NHC)


Percentage of pupils in 10th grade who have experienced bullying, as a percentage of all those who responded to the student survey. The table contains data on bullying and digital bullying. The county figures comprise students who attend school in the county.

In the student survey the term bullying is defined as: ” repeated negative or malicious behaviour from one or more people directed towards a student who has difficulty defending themselves. Repeated teasing in an unpleasant and hurtful manner, excluding a person, defamation, or hitting/pushing someone is also classed as bullying."

Figures for bullying include those who replied "two or three times a month", "approximately once a week" or "several times a week" to the question "Have you been bullied at school during the past few months?"

Figures for digital bullying include those who replied "two or three times a month", "approximately once a week" or "several times a week" to the question "Have you been bullied through digital media (mobile phone, iPad, PC) during the past few months?"

Two measures are available. Use the Measure button to select:
1. per cent = Percentage.
2. ratio (Norway = 100) = Ratio between the county's rate and the national rate for a given year. Examples; ratio = 130 means that the county's rate is 30% higher than the national level. A ratio of 87 means that the county's rate is 13% lower than the national level.

Figures in this table can be different from figures presented in the table "Mobbing i 10.klasse, årlige tall for store kommuner" (Bullying, 10th grade, yearly figures for larger municipalities) in Kommunehelsa statistics bank. The reason is that figures in Kommunehelsa are standardized for sex, and cases where sex is not given are excluded.

Version Responsibility Statement

In the Student Survey for 2016, the questions on bullying were changed. To use these figures to monitor time trends for earlier years can be misleading. Because of this, we have decided to present figures starting with the school year 2016/2017.

Following the change in the questions on bullying, the percentage reporting bullying has increased. The Norwegian Directorate for Education and Training assumes that the statistics is affected by the changes in the questions. Some types of incidents which earlier were included in the questions on offences are now included in the questions on bullying, and the definition of bullying given to the students is now presenting more examples.

Kind of Data

Statistics based on fewer than three cases are hidden for privacy reasons. This criterion applies to the total of cases during the period for which the average is calculated. In practice, numbers are concealed if the following is true for the entire five-year period the number applies to:

• Fewer than three who are bullied or fewer than three who are not bullied
• Fewer than 10 people in the denominator

In addition, statistics for a subset are concealed, e.g. a gender, if the figure for this subgroup, with the figure for the group, could be used to derive a number that is hidden for privacy reasons.

If more than 20 per cent of the numbers in a time series are hidden for privacy reasons, the entire time series is concealed so as not to create a false impression of the situation in the county. Time series are also hidden where more than 50 per cent of the numbers in the time series are based on 6 or fewer cases.

Frequency of updates



Data from the School Survey which is conducted annually in 10th grade.

Data quality

In recent years, the response rate in the student survey has varied between 79% and 92%.


Bullying is a significant individual risk factor for mental disorders (Fosse 2006). Children who are bullied have up to a seven times higher risk of mental health problems such as anxiety, depression, loneliness and restlessness, than children who are not bullied. Among children and youth who are bullied, bodily ailments such as headaches, back pain, "stomach ache" and dizziness are twice as common as among other children. The more frequently a child is bullied the greater the risk of health problems (Nordhagen 2005).

The connection between bullying and health problems emphasizes the importance of preventing bullying in schools. It is also important to monitor the statistics on the proportion who have been victims of bullying to evaluate how the implemented measures work, and to be able to work on local quality improvement.
