Application of ESS Code of Practice is being introduced.

There is no overall assessment of data quality based on standard quality criteria.

Users of data are: academic comunity, general public, government bodies, journalists, international organisations.

One of the key points of quality management in the CBS and within all statistical activities is user needs monitoring. CBS is developing systematic monitoring of suggestions, comments and opinions of their users, and is trying to deliver short-termed replies. Reviewing and analyzing user satisfaction is implemented into regular tasks of the CBS. For business improvement and future planning, it is crucial to accept opinions, attitudes, and users' suggestions with the utmost respect, and take feedback information seriously into consideration.

The goals of survey on user satisfaction are various:

· learning the needs and expectations of statistical data users

· examining user preferences for creation of different products and services

· acquiring feedback on products and services of the CBS in order to improve and further develop them

CBS conducted a user satisfaction survey in November 2013, April 2015 and 2022 (from November 25 to December 23).

Few user satisfaction surveys about CBS's activities on social networks were carried out in 2016 and 2017.

User consultation in CBS takes place in a variety of ways, both formal and informal. The main communication channel with users is the Statistical Council which is the advisory body for strategic issues concerning official statistics and it is established to ensure that user needs are taken into account (Official Statistics Act, Article 20).

Users and general public also have an opportunity to comment and give their opinion on CBS's draft strategies, laws, programmes and plans through application e-Consulting on the Central Government portal. Also, there are many bilateral contacts with the main users, and many informal contacts with occasional users.

CBS set up standing user groups for key statistical areas in the first half of 2017. User groups meetings are held occasionally (according to any open issue). Such groups provide an effective means for collecting feedback on statistical services and products, for informing users about quality and methodology reports and other metadata.

All breakdowns and variable forms are provided, according to the EU regulations in force.

Compilation method for the purpose of transmission to Eurostat: Monthly total amounts of hours worked by employee are summed for the months of each quarter of the year as are the monthly number of persons who received wages.

From those quarterly hours worked, quarterly indices are calculated by dividing quarterly hours worked, with average hours worked, for the base year (2021=100) for each division and section (A-S) of NACE Rev. 2.

Compilation method for national purposes: Average monthly hours worked per employee are calculated by dividing total amount of hours worked by total number of persons employed who received wages.

JDEMETRA method (regression method), which is based on X-13 ARIMA models, is used for the adjustment, on a time series from January 2003. Direct method is used for the seasonal adjustment of time series. In the seasonal adjustment the impact of the number of workdays, Easter and other national holidays was taken into account in those time series for which the mentioned influences were statistically significant. These adjustments are made for the total series, MIGS and selected Divisions.
