With the exclusive use of "rigsdansk", the High Copenhagenian Standard, in national broadcasting, the traditional dialects came under increased pressure. In the 20th century, they have all but disappeared, and the standard language has extended throughout the country. Minor regional pronunciation variation of the standard language, sometimes called "regionssprog" ("regional languages") remain, and are in some cases vital. Today, the major varieties of Standard Danish are High Copenhagenian, associated with elderly, well to-do, and well educated people of the capital, and low-Copenhagenian traditionally associated with the working class, but today adopted as the prestige variety of the younger generations. Also, in the 21st century, the influence of immigration has had linguistic consequences, such as the emergence of a so-called multiethnolect in the urban areas, an immigrant Danish variety (also known as "Perkerdansk"), combining elements of different immigrant languages such as Arabic, Turkish, and Kurdish, as well as English and Danish.
