San Mateo, CA

Metro pages on PlainEmployers gather every employer whose federal filings tie to a single regional labor market, so you can see where H-1B hiring concentrates, which sectors dominate, and how often layoffs are filed in one place. Every figure below comes from the same three public datasets behind individual profiles, the Department of Labor H-1B disclosures, OSHA injury records, and state WARN Act notices, aggregated across the metro. Use these regional numbers as the backdrop against which any single local employer should be read.

Metro-area figures sum the employer records tied to this region's labor market, based on WARN Act notices and US Department of Labor data. Geographic boundaries are approximate: a filing is attributed to the metro of the affected worksite, so a multi-site employer may appear across several metros, and remote reductions can be hard to localize. Local economic conditions, seasonal patterns, and the presence of one or two very large employers can all skew a metro's totals. Use these numbers to understand the broad shape of activity in the area, not as a precise census, and consult the individual records and the methodology for the underlying detail.
