KPI Name Population Living in Disaster Prone Areas
KPI No. SC: SH: SA: 4A Type: Advanced Type: Sustainable

Definition / Percentage of inhabitants living in a zone subject to natural hazards
Description

Rationale / “This indicator refers to the percentage of national population living in areas subject
Interpretation/ to significant risk of death or damage caused by prominent hazards: cyclones,
Benchmarking drought, floods, earthquakes, volcanoes and landslides. The indicator can be
calculated separately for each relevant prominent hazard. The risk of death in a
natural disaster is a function of physical exposure to a hazardous event and
vulnerability to the hazard. The indicator measures the risk at sub-national scale by
using historical and other data on hazards and on vulnerability. The sub-national risk
levels are then aggregated to arrive at national values.” [United Nations]
“To calculate the percentage of population living in disaster prone areas, thus
providing a useful estimate of national vulnerability to cyclones, drought, floods,
earthquake, volcanoes and landslides, which combines almost the totality of human
and economic loss due to disasters caused by vulnerability to natural hazards. This
indicator will contribute to a better understanding of the level of vulnerability in a
given country, thus encouraging long-term, sustainable risk reduction programs to
prevent disasters, which are a major threat to national development”. (UNDESA)
A declining trend and lower values are considered positive.

Methodology Calculate as:
Numerator: Total number of city inhabitants living in areas subject to significant risk
of death or damage caused by prominent hazards
Denominator: Total number of city inhabitants.
Unit Percentage
Data Sources / Data availability at the country level varies according to the country. At the
Relevant international level, data on global hazard frequency and risk and their distribution is
Databases available through the Hotspot project implemented by the Centre for Hazards & Risk
Research at Columbia University. Data on global disasters is available in the EM-DAT
database, maintained by the Centre for Research on the Epidemiology of Disasters
(CRED) in Brussels. (UN)
It is also important to examine Global data sources showing geographical hazard
distribution like volcanic maps, fault lines, etc. These can be mapped against
national population records at the municipal/territorial/national level. See
