How does my iPhone know where I live?

That explains how the iPhone recongizes your frequently-visited locations, but it does not explain how it knows which of those locations is your home address. That information is from your contact record.

The OP already told you he put nothing in his contact record (as have I). It still shows as home or work on its own. The contact record can't be how it works.

And how does it recognize that for many of those who don't have any address information in their contacts at all, as has been pointed out by at least some? And there you go.
Without some other form of confirmation, there is no way iOS can confirm that a frequently-visited location is your home, unless some unfounded assumptions are used. There is no way it would know, for example, that a location visited every night for around 8 hours isn't a night shift job, and not a residence. A pattern of visits doesn't positively identify the nature of the visits or the type of location.
And yet it still able to figure something out with absolutely no address information in contacts or anything like that.
i have not tried this without filling my contacts card, but i too believe the phone must be getting its information from elsewhere, if it doesn't make assumptions based off visited locations.
google now on my android phone advised last saturday how long it would take me to get to a particular nightclub i usually go on those days. an hour or so earlier i had received an sms from the PR of that place which did not include its address. i was left wondering if google picked up on the name and time from that sms or if indeed it tracks my visits to it on saturdays and made an educated guess.
My friend does work for NHS and does night shifts. She have not filled her contact details, however her iPhone 5s tells her without mistake where is home and where is work! Her days off work very!
Who said it was 100% accurate? Of course it's making an assumption without any address information. But it seems that for most people iOS7 is indeed correctly assuming their home location.
It's probably combining multiple sources of data from aGPS, motion sensors, screen on time, charging or not, etc over time. It might erroneously identify your home if you work a night shift job, get there and plug in your phone without touching it until the end of your shift, then at home during the day you have someone constantly checking and using the phone; and do that repeatedly for a week. But obviously that's not typical behavior. If you use your phone normally, even with a night shift job, it will probably still correctly identify your work and home locations just based on all of the combined data it's gathering.
It makes a reasonable assumption. In your example you state that a place you visit for 8 hours a night might be a night shift, but then it probably also notices that you spend a majority of the weekend at this place, so it can infer it is your home.
You just refuse to believe that it works without a contact record. OP clearly stated he had no info in his contact record and yet it still got his "home" location.
I once got the "it would take you xxx minutes to drive to work" on a saturday around 10:30pm.. Don't know why my iPhone thinks I want to work then. I was out with some friends.. Since I am a student, I am never on my campus on Saturday nights..
EDIT: but besides that, it works pretty good for me! Would be even better if it would show bicycle directions, though..

No.

Stop being so foolish. It IS how it works. Test it yourself and remove the contact information, your iPhone will still know where you live and where you go to work.
That is false. I never said it can't work without a contact record. This is what I said:
I never said that other form of confirmation has to be the contact record. As others have stated, it's likely a guess combined with other data points.
Actually one of the things you said did in fact pretty much say that:
Saying the information is in the contact record is not the same as saying it can't work without the contact record, as the information could be in more than one place.
Agreed, although the way that post was phrased it would seem that most people would read it that it was in fact implying that the information essentially has to come from the contact record (and not elsewhere). All of this clarifies that better.
