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)
