From Mental Floss:
Like a lot of people, I have been entranced for the past few days by this animated map of the most popular baby names for girls by state over the past 52 years. It shows how the country shifted from Mary to Lisa before giving over completely to Jennifer, after which the Jessica/Ashley and Emily/Emma battles eventually resolved into the current dominance of Sophia. The map was created by Reuben Fischer-Baum of Deadspin using baby name data from the Social Security Administration. The SSA website gives the top 1000 boy and girl names (as reported on social security card applications) for each year from 1880 onward. This brief historical tour of the most popular names got me curious about the least popular names.
