Enterprises and local units, no matter the legal form or the ownership type, whose main activity belongs to  the divisions of CAEN Rev.2, code 01-99 (except armed forces and staff assimilated (Ministry of National Defense, Romanian Intelligence Office, Ministry of Interior)). The economic subunits/units with 50 employees and more are exhaustively surveyed. Budgetary sector units (public administration, education, health and social assistance, arts, entertainment and recreation activities), are exhaustively comprised into the survey, except public local administration units, for which data at level of local communal council are collected based on representative sample at county level. For economic sector, units of four employees and over were included in the survey, representing (in 2023) 87.28% of total employees in this sector. For the economic sector, the size class units of 4-49 employees are selectively covered based on samples.
