[Excerpt] Employment in the security guards and patrol services industry spiked after the attacks on September 11, 2001 in New York City and Arlington, Virginia. Today, if you work in a large office building in a major city, chances are you have at least one security guard at the front entrance, as well as numerous security cameras mounted around the lobby. But which counties experienced the largest increase in security employment between 2001 and 2002? The over-the-year period between 2001 and 2002 was analyzed in order to depict the immediate response to the September 11th attacks. Five large counties were selected for review because they had the largest percent or level change in employment in the privately-owned security guard and patrol services industry (NAICS 561612).
