Table 11 provides a clear overview of the types of aviation-related organisations that have seen the most growth at Schiphol over the past ten years.
| Business activity | 2002 | 2007 | 2012 | Increase 2002-2012 |
|---|---|---|---|---|
| Security companies | 2,242 | 3,953 | 4,340 | 2,098 |
| Hotels and/or restaurants | 1,640 | 2,460 | 2,934 | 1,294 |
| Various providers of passenger and visitor services | 1,504 | 2,557 | 2,557 | 1,053 |
| Government agencies | 2,411 | 3,032 | 3,451 | 1,040 |
| Other aviation and related organisations | 46,740 | 46,895 | 46,189 | -551 |
| Total number of employees at Schiphol | 54,537 | 58,897 | 59,471 | 4,934 |
The table shows that, in the past ten years, growth in the aviation industry has mainly come from security firms at Schiphol (94% growth in 2012 relative to 2002) and government screening services (43%). This is attributable to the introduction and review of national and international security measures.
Finally, growth was also observed among providers of passenger and visitor services. The number of employees working at hotels and restaurants at Schiphol increased by 79%, and by 70% among other service providers. This growth can largely be attributed to both a rise in passenger numbers, from 41,982,755 (Statistics Netherlands, 2002) to 55,653,320 (Statistics Netherlands, 2012), and the increased use of services by passengers and visitors.
