Actual wage data is used to develop the Salary Check. These wages are provided by visitors to the WageIndicator websites. Because of this, WageIndicator can provide precise and updated salary information for different occupations. The quality of the Salary Check increases with the growing popularity of the WageIndicator websites and the number of submitted surveys. The tool is updated twice a year.
Data Collection
WageIndicator collects data by means of voluntary web-based surveys available at national WageIndicator sites. The survey questionnaires are similar to those used by statistical agencies for standard labor force surveys. They are user-friendly and consist of multiple-choice questions only, except for the question regarding income. The collected data is anonymized and subject to strict security measures, safeguarding the privacy of the participating individual.
DAta Reliability
The wage information used for the calculation of Salary Checks is based on voluntarily submitted data. Therefore, 100% accuracy cannot and will not be guaranteed. WageIndicator encourages its respondents to provide accurate and precise information about their personal and employment characteristics, pointing out that they provide their professional peers and themselves with an improved salary tool.
Before calculation, the dataset is cleaned and compared to other relevant datasets applying universally accepted statistical methods. In this way, WageIndicator eliminates from its datasets most non-trustworthy cases, such as extremely high or low wages.
