The installed Faker 9.9.0 German locale holds 572 male and 583 female given-name entries, plus 1,688 surnames. Ten given names sit in both gender lists, including Kim, Luca and Jamie. Choosing a gender picks a source list. It does not make a name exclusive to that gender or say anything about a real person.
Every name has the same chance of being drawn, with no weighting by birth year, region or real frequency. For real trends, see the first-name ranking from the Society for the German Language (GfdS) in Sources. Its 2025 list is based on 749 registry offices and covers almost 91% of first names given that year. Each name in its boys’ and girls’ top ten, such as Noah and Sophia, appears in Faker’s lists in at least one spelling. Here, though, they come up no more often than any other entry. The ranking is a reference for your research, not the data behind this generator.
For test data, the lists are useful but narrow. Of the surnames, 155 contain an umlaut, such as Böhm or Bühler. None contains the sharp s (ß), a hyphen or a space, so double-barrelled surnames never appear. Only four given names carry an umlaut: Björn, Sönke, Sören and Ömer. Add the missing cases yourself, or start from the name validation test cases. Downloads put the full name in one field. For separate first-name and surname columns, use the bulk test data generator. Germany’s stand-in for an unknown person is Max Mustermann, the German John Doe; the history of placeholder names explains where he and his counterparts come from.
