U.S. call center industry employs about 3.3. million employees

The U.S. call center market continues to expand due to corporate reshoring, onshoring initiatives, and the quest for quality customer service. According to Site Selection Group's proprietary data, there are over 7,400 call centers in the U.S. employing 50 or more workers. These call centers employ an estimated 2.3 million workers.

Call center site selection strategies become more important than ever

As the U.S. call center market has matured over the last two decades, the utilization of site selection strategies has become more important than ever.

These studies include the evaluation of labor availability, labor market longevity and scalability, college graduate output, military presence, labor cost, wage inflation, labor laws, tax conditions, quality of life, accessibility, real estate cost and availability, and economic incentive availability.
