Private security guards have become a common sight across our society, whether they're escorting cash in transit, patrolling shopping malls, conducting screening at airports or protecting VIPs. In many places, the guards dress like police officers and are equipped with firearms.
As Statista's Niall McCarthy notes, private security is booming and the sector is worth approximately $180 billion, a number that's expected to increase to $240 billion by 2020. That's greater than the GDPs of 100 countries including Portugal, Romania and Hungary. An estimated 20 million workers are employed in the private security sector while its biggest company, G4S, has 585,000 employees and revenues of nearly $10 billion.
Research conducted by the Guardian has found that half of the planet's population lives in countries where there are more private security workers than police officers.
