it’d be good to see how many bikes had been stolen from homes, since that’s how many of us feel our bikes are most vulnerable
For practical purposes you could probably count any burglary/housebreaking to a garage or shed as a bike theft when assessing risks in your area since any burglar that found a good quality bike would nearly always take it (assuming it wasn’t locked to a ground anchor or similar).
One of the benefits to living on the outer edge of the suburbs here is that the houses, garages, and sheds of the areas nearer to the city get plundered rather than mine as most of the thieves live inside the city and target places that are easier to get to and easier to get away from.
