Is there any study showing how probabilities of various kinds of aviation (e.g. crash-landings, fatal crashes, mid-air collisions) accidents have increased or reduced over time?

Short answer

The International Air Transport Association (IATA) publishes each year a report about aircraft accidents in the world. The latest one indicates these average figures:

  • There are 3.3 billion passengers per year.
  • There are 100,000 flights per day.

Over the last four years the accident rate decreased from 94 to 73 accidents per year.

In 2014, among these 36,500,000 flights:

  • There has been a total of 73 accidents
  • 12 accidents had fatalities (641 fatalities).

ICAO also publishes statistics which can be viewed online according to custom criteria.
