Other human impacts from disasters

Human impacts from natural disasters are not fully captured in mortality rates. Injury, homelessness, and displacement can all have a significant impact on populations.

The visualisation below shows the number of people displaced internally (i.e. within a given country) from natural disasters. Note that these figures report on the basis of new cases of displaced persons: if someone is forced to flee their home from natural disasters more than once in any given year, they will be recorded only once within these statistics.

Interactive charts on the following global impacts are available using the links below:

• Injuries: number of people injured is defined as "People suffering from physical injuries, trauma or an illness requiring immediate medical assistance as a direct result of a disaster."
• Homelessness: number of people homeless is defined as "Number of people whose house is destroyed or heavily damaged and therefore need shelter after an event."
• Affected: number of people affected is defined as "People requiring immediate assistance during a period of emergency, i.e. requiring basic survival needs such as food, water, shelter, sanitation and immediate medical assistance."
• Total number affected: total number of people affected is defined as "the sum of the injured, affected and left homeless after a disaster."
