Have you ever questioned how large the "janitorial services" industry is in the U.S.? Have you wondered how well the janitorial services industry weathered the Great Recession? Is the industry growing, shrinking, or standing still?

 • Most studies indicate industry growth is four to five percent per year.
 • As of 2012, the industry employed nearly one million people.*
 • In 2012, there were nearly 54,000 janitorial service companies that hired employees.
 • In 2012, there were over 1.2 million non-employer (mom-and-pop) janitorial services.
