Keep the category’s limits in view
The source category is “Security system” under “Interior Additions and Replacements.” A median describes the middle of reported spending; it is not an average bid, a recommended budget or a standardized job.
Missing or withheld values stay unknown. They are not zero and are not filled using neighboring metros. The survey’s metro names and boundaries are retained; no county or ZIP estimate is inferred.
