The two baby names that have plunged in popularity

It's been two years since Caitlyn Jenner announced her new name and gender, and according to America's Social Security's annual list of the most popular monikers for newborns the name Caitlyn plummeted more than any other baby name.

In fact, the four names that dropped the most were all variations of the same name: Caitlin, Caitlyn, Katelynn and Kaitlynn.

'It was inevitable,' said Laura Wattenberg, founder of BabynameWizard.com. 'Caitlyn is suddenly controversial.'

It's not that people are suddenly anti-transgender, Wattenberg added. It's just that parents aren't inclined to name their children after controversial public figures.

Each year, the Social Security Administration releases the top 1,000 baby names.

Emma was the top baby name for girls for the third year in a row and Noah was the top baby name for boys for the fourth year in a row.

The agency also lists the baby names that decrease the most in popularity.

Alongside Caitlyn, the name “Donald” also hit a new low and decreased in popularity quite dramatically.

The US president’s first name was ranked at just 443 in 2015 but last year it dropped 45 spots to an even more pathetic 488.

These are the names that made the top 10:

1. Noah/Emma
2. Liam/Olivia
3. William/Ava
4. Mason/Sophia
5. James/Isabella
6. Benjamin/Mia
7. Jacob/Charlotte
8. Michael/Abigail
9. Elijah/Emily
10. Ethan/Harper
