Is Arlington safer than Boise?
No. Boise's crime index is 73 versus 132 in Arlington, and its violent crime index is 85 versus 130, using 2024-2025 FBI data.
Boise is cheaper. Median rent is $1,446 a month versus $1,470 in Arlington.
Safety is where Arlington and Boise split most clearly. Boise scores 59 points better on the crime index, a gap that shows up in evening walks, parking situations, and insurance rates. Rent runs $1,470 in Arlington and $1,446 in Boise.
Boise is not a close call here. It leads on cost of living, the job market, and safety by margins that add up in daily life. Arlington makes sense if you have a specific reason, a job offer, family, or a neighborhood you already know, but on the numbers alone Boise is the stronger move.
The crime gap is citywide. Boise has rougher pockets and Arlington has quiet ones: the index tells you the average, not your block.
