Demographic features of the population of theCzech Republic include population density,ethnicity, education level, health of the population, economic status, and religious affiliations.

With an estimated population of 10.5 million as of 2022, compared to 9.3 million at the beginning of the 20th century, the population growth of the Czech Republic has been limited, due to low fertility rates and loss of population in and around World Wars I and II. Population loss during World War I was approximately 350,000. At the beginning of World War II the population of the Czech Republic reached its maximum (11.2 million). Due to the expulsion of the German residents after World War II, the Czech Republic lost about 3 million inhabitants and in 1947 the population was only 8.8 million. Population growth resumed, and in 1994 the population was 10.33 million.
From 1994 to 2003 natural growth was slightly negative (−0.15% per year) and the population decreased to 10.2 million. Since 2005, natural growth has been positive, but in recent times the most important influence on the population of the Czech Republic has been immigration: approximately 300,000 during the 2010s.
The Czech Republic has a population density of about 134 inhabitants per square kilometre, which is above the European average. The areas with the lowest population density are located along the mountainous southwestern and southern borders of the country. These regions were significantly affected by the displacement of the German population after World War II.[4]

definition: NA
The majority of the 10.5 million inhabitants of the Czech Republic are ethnically and linguisticallyCzech (95%). They are descendants ofSlavic people from the Black Sea-Carpathian region who settled in Bohemia, Moravia and parts of present-day Austria in the 6th century AD. Otherethnic groups includeGermans,Romani people,Poles, andHungarians. Historical minorities like Germans and Poles are declining due toassimilation. There is also a growing community fromVietnam. Other ethnic communities likeGreeks,Turks, Italians, andYugoslavs are found in Prague. Since thedissolution of Czechoslovakia,Slovaks living in the Czech Republic have comprised roughly 3% of the population.
There are different groups of national and ethnic minorities in the Czech Republic. The only "old minority" isPoles in theTrans-Olza region, while the "new minorities" are scattered among the majority population (generally in the larger towns). While some of the minorities have the whole social structure of Czech society[clarification needed] (Poles,Slovaks,Greeks andUkrainians), other represent only some of the social groups (i.e. Russian newcomers of middle class, andRomani people who generally represent the underclass).[21]

| 1 On the territory of the census date. | ||||||||||||||||||||
1 In 2011 a large part of the population did not claim any ethnicity, before the census it was widely mediatized that the question is not mandatory. The vast majority of those who did so are presumed to be ethnic Czechs, number of whom dropped by roughly the same amount that the number of undeclared people rose, circa 2.5 million.
The legal position of the minorities is defined foremost in the Act No. 273/2001 Coll. (The Rights of the Minorities Act) which implements theCharter of Fundamental Rights and Basic Freedoms,Framework Convention for the Protection of National Minorities andRecommendation of theCouncil of Europe No. 1201. There is a number of other enactments which to lesser extent deal with the minorities.
A special situation applies in the case ofMoravians andSilesians, who are frequently allocated within the group of Czechs when it comes to the statistical data.
Minorities, which "traditionally and on a long term basis live within the territory of the Czech Republic" enjoy some privileges. As of 2022 there are 14 such officially recognized minorities, which are (alphabetically):Belarusians,Bulgarians,Croatians,Germans,Greeks,Hungarians,Poles,Romani people,Russians,Rusyns,Serbs,Slovaks,Ukrainians andVietnamese.[25]
Citizens belonging to the officially recognized minorities enjoy the right to "use their language in communication with authorities and in courts of law". Article 25 of the CzechCharter of Fundamental Rights and Basic Freedoms provides the right of the national and ethnic minorities to education and communication with authorities in their own language. Act No. 500/2004 Coll. (The Administrative Rule) in its paragraph 16 (4) (Procedural Language) provides that a citizen of the Czech Republic who belongs to a national or an ethnic minority, which traditionally and on a long-term basis lives within the territory of the Czech Republic, has the right to address an administrative agency and proceed before it in the language of the minority. In the case that the administrative agency does not have an employee with knowledge of the language, the agency is bound to obtain a translator at the agency's own expense. According to Act No. 273/2001 (About The Rights of Members of Minorities) paragraph 9 (The right to use language of a national minority in dealing with authorities and in the courts of law) the same also applies to members of national minorities in the courts of law.
Bulgarians
The economic migration of Bulgarians to the Czech Republic began in the 1990s. 4,363 citizens claimed to have Bulgarian nationality in the 2001 census. They mostly live in the large cities and towns, such asPrague,Brno,Ostrava,Karlovy Vary,Kladno,Ústí nad Labem,Děčín, andHavířov. Nowadays the newcomers from Bulgaria aim for these areas in particular, where they can join an already established community. Many of these economic immigrants have dual citizenship of both the Czech Republic and Bulgaria. However most of the recent immigrants still only have Bulgarian citizenship.
The Bulgarian Cultural Organisation publishes the magazineRoden Glas, while a folklore organisationKytka promotes traditional Bulgarian dances. Among other organisations arePirin,Zaedno,Vazraždane andHyshove.[26]
As an officially recognized minority the Bulgarian citizens of the Czech Republic enjoy the right to use their language in communication with authorities and in the courts of law. They also enjoy a number of other rights connected to the status of recognized minority, e.g. the right to education in their own language: the first Bulgarian school in the current Czech Republic was established in 1946 in Prague.
Germans

The German minority of the Czech Republic, historically the largest minority of the country, was almost entirely removed when 3 million wereforcibly expelled in 1945–46 on the basis of thePotsdam Agreement. The constitution guarantees rights for minority languages, however there are 13 municipalities with German minority constituting 10% of population, which qualifies for such provisions.[28] There is no bilingual education system in Western and Northern Bohemia, where the German minority is mostly concentrated. However, this is in large part due to the absence of German-speaking youth, a heritage of the post-war policy of the Communist government.
According to the 2001 census there remain 13 municipalities and settlements in the Czech Republic with more than 10% Germans.[28]
Many[citation needed] representatives of expellees' organizations support the erection of bilingual signs in all formerly German-speaking territory as a visible sign of thebilingual linguistic andcultural heritage of the region, but their efforts are not supported by some of the current inhabitants, as the vast majority of the current population is not of German descent.
The German-Czech Declaration of 21 January 1997 covered the two most critical issues—the role of someSudeten Germans in the breakup of Czechoslovakia in 1938 and theirexpulsion after World War II.[29]
Greeks
Another influential minority areGreeks. Large numbers of Greeks arrived inCzechoslovakia during the end of theGreek Civil War. The first transports of Greek children arrived in 1948 and 1949. Later, more transports, also including adults, arrived.[30] They were partly leftists, communists and guerillas with their relatives, hence the willingness of Czechoslovak government to allow the immigration.[31] This was viewed rather as a temporary solution. After the defeat of DSE and other left-wing guerillas, the Greeks stayed in Czechoslovakia. In total more than 12,000 Greeks immigrated to Czechoslovakia between 1948 and 1950.[31] Today, there are about 7000 Greeks in the country (3219 according to 2001 census data),[31] mostly in the 3 biggest towns –Prague,Brno,Ostrava – and also inBohumín,Havířov,Jeseník,Karviná,Krnov,Šumperk,Třinec,Vrbno pod Pradědem andŽamberk (apart from the last one these towns are inSilesia).[32]
Poles
The most concentrated linguistic minority in the Czech Republic are ethnicPoles, historically the plurality, today constituting about 10% of the population ofKarviná andFrýdek-Místek districts. Poles have the right to use their language in official dealings; the public media (Czech TV andCzech Radio) regularly broadcast in Polish; and there are many Polish primary and secondary schools in the area. The Polish minority has been decreasing substantially since World War II as education in Polish was difficult to obtain, while Czech authorities did not permit bilingual signs to maintain Polish awareness among the population.
The erection of bilingual signs has technically been permitted since 2001, if a minority constitutes 10% of the population of a municipality. The requirement that a petition be signed by the members of minority was cancelled, thus simplifying the whole process.[33] Still, only a couple of villages with large Polish minorities have bilingual signs (Vendryně/Wędrynia for instance).
Romanis
Another minority is theRoma, who nonetheless have very little influence on Czech policy. Around 90% of the Roma that lived in the Czech Republic prior to World War II were exterminated by theNaziPorajmos. The Roma there now are 80% post-war immigrants from Slovakia or Hungary, or the descendants thereof. In total, the Roma in the CR now number around 200,000.[34] There is Romani press in the CR, written in both Czech andRomani, but Romani radio is broadcast in Czech and there is no Romani television. Romani is also absent from legislative, judiciary, and other political texts but it has recently entered some university and elementary school courses.Life expectancy,literacy,median wage, school enrolment, and other socio-economic markers remain low while Roma compose the majority of prison and habitual offender populations despite accounting for only a fraction of a percent of Czech population.[35]

According to the Czech Statistical Office as of 31 December 2020 there were 632,570 legal foreign residents in the Czech Republic (5.1% of the total population).[36] Residents fromUkraine are the largest group (165,356), followed by residents ofSlovakia (124,544). There are also Asian immigrant communities in the Czech Republic. The largest is theVietnamese one (62,842) followed by the Mongolians (10,135) and the Chinese (7,940). During the communist era the governments of Czechoslovakia andVietnam had a deal concerning the education of Vietnamese people in Czechoslovakia. Vietnamese people came to Czechoslovakia for the first time in 1956 and then the number of new migrants grew until the fall of communism. First generation Vietnamese work mostly as small-scale businessmen in markets. Still, many Vietnamese are without Czech citizenship. One of the towns with the largest Vietnamese communities isCheb. Other large immigrant groups come from Russia (41,692),Poland (20,733), Germany (20,861),Bulgaria (17,917) andRomania (18,396).

TheCzech language (divided into three dialects inBohemia, fourdialects in Moravia, and two dialects inCzech Silesia) is the official language of the state. There is also the transitionalCieszyn Silesian dialect as well as thePolish language inCieszyn Silesia, both spoken in Czech Silesia. Various Sudeten German dialects are currently practically extinct: present Czech Germans speak mainly Czech and/orStandard German.Czech Sign Language is the language of most of the deaf community.
The Czech Republicofficially recognizes a series of minorities who have legal status and may use their own language to conduct official business, which results in a series ofminority languages that may be used officially by members of the recognized minority groups.

The 2021 census did not contain list of religious organisations and they had to be written by the respondent (unlike in the previous ones). Therefore another 231 thousand people responded withcatholicism or similar response, 71 thousand people identified simply withChristianity and 27 thousand people claimed to beprotestants orevangelicals. Moreover, after doubling their followers the Orthodox Church of the Czech Lands and Slovakia was the 2nd strongest church in 2021 census with 40,681 faithful.
Almost half (45.2%) of the Czech population prefer not to respond to religious questions in the Census. Others claim to haveno religion or that they are withoutreligious affiliation (34.2%). In comparison, one in every five claims to have some personal belief (20.6%).
The largest denominations areRoman Catholicism, estimated at 10.3% of the population,Protestant (0.5%),Hussites (0.4%). Other organized religions, including non-organized believers, totalled about (9.4%) (as of Census 2011).
According to theEurobarometer Poll 2005,[46] 19% of Czech citizens responded that "they believe there is a God", whereas 50% answered that "they believe there is some sort of spirit or life force" and 30% that "they do not believe there is any sort of spirit, god, or life force"; the percentage of believers is thus the lowest of EU countries afterEstonia with 16%.[47]
