The armed forces are a huge part of the life in Lebanon, employing 6.16% of the workforce.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 23.02% of the workforce. While this number may seem small overall, as a fraction of the total workforce this is high compared to the rest of the county.

Other at-home workers may be self-employed people who operate small businesses out of their homes.
