The Swiss Federal Statistical Office (SFSO) has published a hitparade of most frequently used first names for babies born in 2019.
Some key data for 2019. Female births – 42,049. Male births – 44,123. In the following chart only the first 203/205 names of this hitparade were used. They account for 20,935 (~50%) and 21,993 (~50%) births respectively.
Before doing any actual statistics with the data from SFSO, I just wanted to chart the number of occurrences of the names and see how this looks like.
For female and male names this looks like this (red lines are linear and logarithmic “trends”):
I would have expected a more linear decline in occurences of names but it looks almost like an exponential decline.
