The following data comes from a data set of baby names. The information below is copied from the ReadMe file for this data set.
For each year of birth YYYY after 1879, we created a comma-delimited file called yobYYYY.txt. Each record in the individual annual files has the format "name,sex,number," where name is 2 to 15 characters, sex is M (male) or F (female) and "number" is the number of occurrences of the name. Each file is sorted first on sex and then on number of occurrences in descending order. When there is a tie on the number of occurrences, names are listed in alphabetical order. This sorting makes it easy to determine a name's rank. The first record for each sex has rank 1, the second record for each sex has rank 2, and so forth.
To safeguard privacy, we restrict our list of names to those with at least 5 occurrences.
For example, the names of babies born in 2000 can be found in the file https://dlsun.github.io/pods/data/names/yob2000.txt.
