Nearly 11% of 4 digit passwords are '1234'

"I was able to find almost 3.4 million four digit passwords. Every single one of the of the 10,000 combinations of digits from 0000 through to 9999 were represented in the dataset.
The most popular password is  1234  …
… it’s staggering how popular this password appears to be. Utterly staggering at the lack of imagination …
… nearly 11% of the 3.4 million passwords are  1234  !!!"
Data:  "By combining the exposed password databases I’ve encountered [from leaks], and filtering the results to just those rows that are exactly four digits long [0-9] the output is a database of all the four digit character combinations that people have used as their account passwords.
Given that users have a free choice for their password, if users select a four digit password to their online account, it’s not a stretch to use this as a proxy for four digit PIN codes."
