I've been crunching the numbers for how common various birth numbers are in the USA based on demographic data from the US Census Bureau.

Every fully-reduced birth number (1, 2, 3, 4, 5, 6, 7, 8, 9) is equally common, with 11.1% of the population, each. However, 11's are far more common than "pure" 2's, consisting of around 80% of them. (This reached a peak of 90% around the year 2000, and will continue to fall in the decades ahead, though 11's will remain the majority.) 22's, on the other hand, are rather uncommon, presently only around 20% of 4's: this share will grow in the decades ahead, but "pure" 4's will remain the majority.

So to my fellow 11's, don't get a big head: there are a lot of us!
