In 2015 I discovered the Baby Names from Social Security Card Applications-National Level Data data set, which includes the year, name, gender, and total births for each year from 1879 to the present. After playing with the data and making various charts on specific names, one question kept popping up in my mind, what names have switched genders?

I set the question aside because I wasn’t sure of how to proceed. Fast forward two years and I am going to answer the question. Using a combination of R and Tableau, here is an interactive chart to show the results.
