According to the US Census Bureau's 2014 American Community Survey, there's A LOT of us that marry within our professions.
The survey revealed that the most common profession to marry within is college school teachers.
If you work in any of the above professions, you're more likely to date (and eventually marry) a co-worker!
The survey also claimed that high-earning women, such as doctors or lawyers, are more likely to end up with men who earn around the same income as them.
However... high-earning men tend to marry women who don't earn as much as them.
Interesting.... very interesting.
