This dataset includes all jobs of individuals registered in the BRP (Personal Records Database) working in organizations registered in the ABR (General Business Register) existing in September of a given year. Each observation represents one unique job during the month of September between 2006 and 2023. All compensation and working hours accumulated within the same job during the month of September are summed up in one observation. Job IDs are made longitudinally consistent using SPOLISLONGBAANBUS. One main job per individual is identified using SPOLISHOOFDBAANBUS.

This dataset is only available under strict conditions within the Microdata environment at CBS. Since this is a project-generated dataset made available for reuse via the CBS Data Storage, access to the following source CBS files has to be requested:

A detailed overview and codebook of all variables included in this dataset are available in the NIDIO manual (see osf.io/9b2xh/). The NIDIO manual also lists the original source variable from which each variable in the dataset is derived. The NIDIO variable descriptions and labels are in English. The dataset includes 31 variables and broadly covers the following content of SPOLIS:

Various identifiers (year; rinpersoon; beid; baanrugid; ikvid; slbaanid) Job characteristics during September in year XXXX (e.g., cao status; contract type; ft factor; overall starting date of job; …) Total compensation during September in year XXXX (decomposable into various components) Total working hours during September in year XXXX

The combination of the variables year, rinpersoon and baanrugid / ikvid is the unique identifier of each observation.
