However, the refutations I read were based on Census data and didn’t seem super rigorous since 1) censuses include children born in the Church, and 2) not everybody in a Utah Census is LDS. To get a clearer picture of converts to the Church, I wrote a program that scraped the helpful Overland Pioneer Database and created a spreadsheet of names, ages, and what year they traveled. (While I’ve posted the code, fortunately/unfortunately the overland database was very recently merged into the Church History Biographical Database, so the code is already out of date). I then calculated percent female of adults for each cohort.
