I think a smart burglar would just look at any commonly available database of home sales. Anybody who has moved in the last few years into a more-expensive-than-average house should correlate much better with valuables than iPhones.
However, I'd hope any criminal with brains like that would find something to do that has higher yield and lower risk than housebreaking. I'd suggest working for a private equity company.
Yeah i'm not really worried that burglars are going to use this data-set for harm. If they know about this data-set they likely know about databases of home sales or car sales or just plain old census data listing the average income by county.
