The data on the numbers of ICT specialists are obtained from the Labour Force Sample Survey. In order to ensure higher reliability and to eliminate considerable year-on-year fluctuations of values for this group of employees, data in the table are provided as three-year moving averages (i.e., for example, the value for 2021 is calculated as an average from the values for 2020, 2021, and 2022).

Data on wages of ICT specialists comes from the structural employee wage statistics. It is generated by merging of databases of the sample survey of the Information System on Average Earnings of the Ministry of Labour and Social Affairs (cover the wage sphere), and of the administrative data source of the Salary Information System of the Ministry of Finance (cover the salary sphere).
