The majority of our clients use the geographic differential approach if they hire remotely across the U.S..
For example, they use US (All) - 115% Market Data Cut for employees within a 60-mile radius of the New York City and/or San Francisco Bay areas. The 115% geographic differential on US national average (US (All) Market Data Cut) data reflects the cost of labor + cost of living for these respective metro areas.
Companies like to use US-115% more often than the NYC area data cut b/c it's more scalable for remote hiring (e.g., 115% can be used for San Francisco Bay Area employees too). We recommend keeping the US-115% vs. using NYC area market data cut for NYC area employees.
