Number of jobs in the Netherlands 2018, by type of contract

The source adds: "an employed person may have more than one job at a time. In that case the person has a main job and a secondary job. Each job counts separately. For the calculation of the average number of jobs in a certain period the starting date and end date of a job is taken into account. The weekly working hours are left out of account. Two successive jobs both with a 6-month working period will always count as one job in the average number of jobs, regardless of whether these jobs are full-time or part-time."
