In addition to the other commenters, "burglary" generally includes breaking and entering a vehicle as well, so without further information it's hard to tell what percentage is attributable to each. Particularly since the OP is interested in "an extra layer of home security", if home burglaries are a lower %, then those numbers could seem inflated with regards to the issue at hand.
Additional factors just from the linked page are:
1.) Burglaries of residential properties accounted for 74.5, of which the OP specifically mentions
2.) 60.6 percent of burglaries involved forcible entry, and 6.3 percent were forcible entry attempts.
So naively (without additional data on if forcible entry is less or more common for commercial or residential properties), then one could assume that a more realistic number is 2.2M * .745 * .669 = 1.09M which is about half the chance given the "totals".
This is also compounded if the OP is actually living in a "safe" area (or if it just feels that way)
A higher burglary rate than the US in both rankings are Switzerland, Sweden, Denmark, Iceland, New Zealand, and Australia.
(In fact, that makes me wonder a little whether these numbers might be a mix of both "burglaries" and "whether the citizenry even bothers to report" – with other countries having more burglaries that people don't report because it doesn't help...)
At the risk of being downvoted into oblivion: No guns.
In the US, if you're going to assault someone, they may well be packing. It makes you think twice. But in the UK, you know they're not (with close to certainty), so the only question is whether you're tougher than them.
And most of them happen in concentrated areas (inner city), which means that the vast majority live in safe areas. If you aren't living in Gary, Indiana or somewhere similar, it's pretty silly to be scared of burglary. Perfectly reasonable to take precautions, but it's crazy to go overboard.
Pretty high in relation to what? I live in the Netherlands, which is considered to be a safe country, right? We have 0.00539 B&E's per inhabitant, whereas the US have 0.068 B&E's per inhabitant. Not that much difference, if you ask me.
