This pretty neat chart from Jezebel shows the most popular names by state over the last 50+ years. It’s crazy to watch names flood the country.
On Quora, Jon Pennington went into great detail exploring why certain names may have been popular when they were. It’s speculative as hell, but still interesting. I’m also interested by the idea the people I know with these popular names are all a good 5-10 years ahead of the peak popularity of their names.
1962-1969: Lisa (The graphs show that Lisa wasn’t a common name until c. 1940. Its popularity gradually increased from the 1940s to the 1950s, then increased exponentially from the 1950s to the 1960s. A likely cause of the exponential increase in popularity in the 1950s might be Nat King Cole’s Mona Lisa, a very popular song that came out in 1950, but that doesn’t explain why the name started becoming more common in the 1940s. Another factor that may have sustained the name’s popularity could be the first US tour of Leonardo da Vinci’s Mona Lisa, which took place in 1963.)
