The Czech Statistical Office: what it publishes and how to read it

When a Czech newspaper reports that wages rose, unemployment stayed low or the population grew because of arrivals from abroad, the numbers almost always come from one place: an office in Prague and a website that is more useful than most people realise. The Czech Statistical Office (Český statistický úřad, ČSÚ) produces the country's official statistics, and its habits, such as its release calendar and its definitions, are what make Czech economic news legible.

This guide explains what the Office publishes and how to read it. It does not cite current figures, since those change with each release.

What the Office is

The ČSÚ is a central state administration body, governed by the State Statistical Service Act (no. 89/1995 Coll.). It collects, processes and publishes statistics, coordinates the statistical activities of other bodies and represents Czechia in the European Statistical System, which means it supplies data to Eurostat and follows EU standards. Its chair is appointed by the President of the Republic on the government's proposal, and the law and EU code of practice require professional independence in the methods and the timing of publication.

It also administers registers: the register of persons, from which the IČO identifier for businesses comes, as our piece on tax identification numbers describes. So the Office touches both the data and the plumbing of Czech administration.

The release calendar

The Office publishes a calendar of releases in advance, listing the day on which each statistic will appear. This is not a bureaucratic nicety. It prevents selective release and lets markets, companies and journalists plan. Major releases appear at a fixed time, and the embargo is strict until then.

If you follow Czech economic news, the calendar is the first page to bookmark. It shows which numbers are due this week, which are flash estimates and which are revisions.

The main releases

Consumer prices. The monthly consumer price index, with breakdowns by division. Covered in our explainer on how the index is measured.

National accounts. Quarterly and annual GDP, with expenditure, production and income breakdowns, as described in how the Office measures GDP.

Labour market. The Labour Force Survey, run quarterly, and data on employment, wages and vacancies. The average wage series is closely watched, as it feeds into thresholds in the tax and social systems.

Industry, construction and retail. Monthly indices of industrial production, construction output and retail sales. Industrial production matters in a country where manufacturing is a large part of the economy.

Foreign trade. Exports and imports by country and product, a vital series for an economy so open to trade.

Demography. Births, deaths, marriages, migration and the number of foreigners, with regional breakdowns.

Regions and municipalities. Data for each region, district and municipality, including Prague and its districts.

Two unemployment rates

This catches out many readers, including journalists. The Statistical Office's Labour Force Survey follows an international definition from the International Labour Organization: a person is unemployed if they have no job, are actively seeking one and are available to start. It is based on a sample of households and gives a rate that can be compared across countries.

The Labour Office (Úřad práce) counts people registered as job seekers at its offices. This produces a register-based figure that depends on who chooses to register and on the rules for benefits. It can be higher or lower than the survey figure and is not directly comparable internationally.

The census

Every ten years the Office carries out a census of people, households and housing. The most recent took place in 2021, and the next will follow around 2031. The 2021 census relied heavily on existing administrative registers as well as an online questionnaire, which was a shift from earlier paper-based counts. Its results gave a population of about 10.5 million and detailed information on age, education, housing, nationality and religion.

The census is the benchmark against which annual population estimates are checked. For people interested in the foreign-born population, the Office also publishes the number of foreigners with residence in Czechia, based on data from the Ministry of the Interior's registers, with a breakdown by nationality and region.

Why the average wage matters beyond the news

The average wage is not only an economic indicator. Several thresholds in the Czech tax and social systems are defined as multiples of an average wage figure, so the number published for a year decides, for some people, where a higher rate begins or where a cap on contributions falls. The Ministry of Labour and Social Affairs announces the figures used for these purposes, built on data from the Statistical Office. If your income is close to such a threshold, find the figure for the year rather than relying on an old article. Our piece on employee income tax describes where the thresholds sit.

Using the public database

The Office runs a public database where users can build their own tables from thousands of series, choosing time periods, regions and categories and exporting the data. It is a good place for anyone who wants to check a claim, rather than relying on a chart in a newspaper. English versions of the main releases and database labels exist, though some detailed tables are in Czech only.

Eurostat's database offers harmonised data for all EU countries and is the better source for comparisons. The two should agree where definitions match, and where they do not the difference is usually explained in the notes.

How to read a release

A good habit is to ask four things of any figure. What exactly is measured, and in which units? What is the reference period? Is it provisional, and by how much has it been revised before? And what is the definition used, national or international? The release notes answer these. A sentence like "wages rose by x%" can mean nominal or real, mean or median, gross or net.

The average wage deserves special mention. It is a mean, so a small number of very high salaries pull it up, and the typical worker earns somewhat less. The Office publishes median wages too, and the difference is informative.

Limits and cautions

Statistics are estimates. Surveys have sampling errors, administrative data have gaps, and definitions change. The Office is open about these limits in its methodological notes. Preliminary figures are revised, sometimes substantially, so a later release may change the story. And not everything that matters is measured, especially informal activity and some forms of housing.

When you quote a number, quote the source, the date and the definition. That discipline, which every newsroom at its best follows, is also what the Office itself practises.

Frequently asked questions

Where can I find official Czech statistics in English?

The Czech Statistical Office website has an English version covering the main releases, and Eurostat publishes comparable data for all EU countries.

When is the next census?

Censuses take place every ten years. The latest was in 2021 and the next is expected around 2031.

Why are there two unemployment rates?

One comes from a household survey with an international definition. The other counts people registered at the Labour Office.

Are the figures revised?

Yes. Early estimates are replaced by fuller data, and the Office flags revisions in its releases.
