U.S. Space Workforce
The most authoritative source of U.S. space industry workforce data is the Bureau of Labor Statistics. U.S. space industry core employment is measured by assessing the six BLS North American Industry Classification System (NAICS) codes detailed in Exhibit 4b. While NAICS codes reflect an official U.S. government approach to understanding and measuring employees and salaries, in some cases NAICS codes combine workers from different industry sectors under the same labor category, complicating an exact labor count.
According to data published by the U.S. Bureau of Labor Statistics (BLS), more than a quarter million Americans are employed in the space industry. The most recent (2006) estimate by the Federal Aviation Administration Office of Commercial Space Transportation calculates the combined direct and indirect value of the U.S. space industry, including the secondary and tertiary economic activities it enables, at approximately $## billion.
In 2007, nearly ## U.S. personnel were employed in the space industry. A 2008 U.S. government report estimated that approximately ## U.S. workers were indirectly employed in the provision of primary, secondary, and tertiary goods and services related to space.
