Overview
- Berlin recorded about 2,400 changes, with further high totals in Hamburg (~900), Munich and Cologne (each just under 700), Frankfurt (just over 440), and Düsseldorf (300).
- Leipzig leads per capita with about 151 changes per 100,000 residents, followed by Hannover (98) and Bonn (86), and responses indicate more switches from female to male than other options.
- Applications have been possible since August 2024, with declarations allowed after a three‑month wait and due within six months, and many cases are forwarded to the birth‑registry office.
- Registrations more often lapse when deadlines are missed, while formal rejections are rare and typically stem from name mismatches, disallowed characters, or missing guardians’ consent for minors.
- The Families Ministry has begun a nationwide data query to evaluate the law, and the government expects volumes to ease after the initial surge to an average of around 4,000 applications annually.
