Methodology

How this page is built

The salary figure is the mean annual wage reported by the BLS Occupational Employment and Wage Statistics (OEWS) program for this occupation and metro area. Percentile and national-average comparisons are calculated directly from the 188 cities currently in this dataset, not from a fixed external benchmark. Cost of living, crime and housing figures come from BEA, FBI and Zillow respectively — see "Data transparency" above for the exact sources and reference years used on this specific page.

Confidence: the RSE (relative standard error) shown under Overview indicates how reliable the salary estimate is for this metro — a lower RSE means a larger underlying sample.
