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. Still, only a couple of villages with large Polish minorities have bilingual signs (Vendryně/Wędrynia for instance). Romanis Another minority is the Roma, 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 the Nazi Porajmos. 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. There is Romani press in the CR, written in both Czech and Romani, 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. Immigration 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). Residents from Ukraine are the largest group (165,356), followed by residents of Slovakia (124,544). There are also Asian immigrant communities in the Czech Republic. The largest is the Vietnamese one (62,842) followed by the Mongolians (10,135) and the Chinese (7,940). During the communist era the governments of Czechoslovakia and Vietnam 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 is Cheb. Other large immigrant groups come from Russia (41,692), Poland (20,733), Germany (20,861), Bulgaria (17,917) and Romania (18,396).
