Mary free fall continues

For the past two years I’ve been tracking the fate of the name Mary as given to girls born in the U.S., spurred by the observation that Mary was no longer in the top 100 names, after an unparalleled run at #1 that lasted for all but six years of recorded history.

It’s a difficult job, but it’s got to be done. (Follow the Mary tag for historical background, examples, and more figures.)

So: 2012 was another rough year, according to data from the Social Security Administration.

There was another 5% drop in the number of Marys born, and as a result Mary fell a record 11 ranks, from 112 to 123. The 2,535 Marys born in 2012 were a mere 0.13% of the 1.9 million girls recorded born. Once upon a time, in 1880, more than 7% of all girls born were named Mary.

I have a simple model which predicts that the number of girls named Mary will decline at a rate equal to the average decline over the previous five years — what falls continues to fall. This year, out of 1.9 million girls born and 2,535 named Mary, my model was off by a microscopic 79 girls. The model predicted the number of Marys to within 3.2%.

Take that, indeterminancy, free will, or postmodernism (your pick).

P.S. Despite the continued free fall of Mary, my model missed low, incidentally — or, Mary-naming Americans beat expectations by 3.2%. Since my Mary post on the Atlantic site last December was shared more than 5,000 times, unless proven otherwise we have to assume the 79-girl bump was a Mary-name-blog effect.

By request, here is the trend for Maria. It is not the case that Maria is replacing Mary — both are trouble. In fact, with Maria falling steeply in the last decade, she has also dropped out of the top 100 for the first time since 1943!


Speculation: As Marias of Latina origin grow more common, perhaps their increase is not enough to compensate for the resulting perception among non-Latinas that Maria is a Spanish name. (Remember, this is just girls born in the U.S.)
