What does the survey comprise?
This survey provides on an annual as well as a quarterly basis insight into the population size and composition of jobs of foreign-born employees working in the Netherlands. Figures are broken down by age, gender, type of contract, hourly wage, industry branch, migration background, and being registered as a Dutch resident or not.
The target population comprises foreign-born employees aged 18 to 74 years. A distinction is made between employees who are registered as a resident and those not registered as a resident in the Personal Records Database (BRP; formerly known as the GBA). The target population comprises employees who were at least 18 years old when they immigrated to the Netherlands (in case of employees who are registered as a resident) or at the start of their stay in the Netherlands (in case of non-resident employees).
For this survey, the Social Statistics Database (SSB) is consulted. This data file contains information about both people who are resident in the Netherlands and those who are not resident but who do have a fiscal relationship with the Netherlands. The SSB contains information about people who have a job in the Netherlands, people receiving welfare or pension from the Netherlands, and people who are studying in the Netherlands.
For those employees who are resident in the Netherlands, the demographic variables in the SSB are exclusively drawn from the BRP. These variables include, for example, gender, date of birth, country of birth, and nationality of all persons who are or were recorded in the registered population from 1995 onward. Demographics of foreign-born employees who are not registered as residents are largely drawn from the Non-residents Records Database (RNI) of the BRP. For small share of the non-resident foreign-born employees, demographic data are drawn from others sources, such as the Policy Record Administration of the Employee Insurance Agency (UWV, responsible for the implementation of social insurance and benefits) and the Tax and Customs Administration (‘Belastingdienst’ in Dutch). For the entire target population, job characteristics are derived from the Policy Record Administration.
The industry branch corresponding to the job comes from the General Business Register (ABR) of the CBS. The ABR contains company data per company unit. Up until the end of 2014, some corrections were made during the processing of Policy Records. Most of these corrections were related to SBI (Standard Industrial Classification) 64200, referring to Financial institutions. In cases where the sector code listed in Policy Records was different from the SBI 64200, this SBI was recoded into a code more in line with the sector code. Since 2014, such recoding is no longer applied. The break which occurs as a result can be seen when selecting 'Financial services'.
