Opinion: There is no such thing as an overused name (anymore)

Based on the most recent SSA data for 2023, even the most popular names are, relatively speaking, fairly uncommon. In 2023, "Liam" was given to only 1.14% of boys, and "Olivia" to only 0.87% of girls, each being the top name for boys and girls respectively that year. The top 10 drops off steeply, with #10 "William" and "Luna" being only 0.57% and .45%, respectively.

Compare to 1993, when "Michael" was at 2.4% and "Jessica" at 1.77%, and almost all of the top 10 names for boys and girls were over 1%. Compare again to 1963, when "Michael" was at 4.05% and "Lisa" was at 2.82%. Name diversity has been increasing every year, such that children born today are very unlikely to have the "there are four Mikes in my class" experience that millennials did, or the mid-century "everyone I know is named Mary".

Of course, there will be local variations in popularity, but whatever you choose, nowadays it's much less likely that someone with even the most popular name will know many people with the same name.
