This paper examines the many recent fluctuations in the forename stock in Sweden, both concerning the contents of the stock, and the popularity changes over the last decades. Many more names are now in use, and even more names have changed in frequency. This is partly a natural phenomenon, but it also reflects changes in the population structure. Which names are the popular names today? Where do the new names originate from? How many new names have reached a certain number of bearers? When new immigrant groups replace older ones, how is that reflected in the name stock? Are more pet forms of first -names used as official names nowadays? How are the latter, more liberal judicial interpretations of the Personal Names Act valid 1983–2017 reflected in the name usage? These questions are discussed in this paper. Comparisons are made between the stock of spoken names of all Swedish residents in the late 1990s and the current popular names of both babies and all Swedish residents.
