Today, two fundamental approaches are gaining attention in health geography: first, geographical epidemiyolgy,
which examines the geographical distribution of diseases, and second, techniques providing a visual aspect to
health planning and health services’ spatial range (1).
Knowing the geographical dispersion of diseases is one of the essential conditions for a country’s health politics
and investment in healthcare (2). With the developments in geographic information system (GIS) technology and
statistical methods, health and population data can be evaluated together in an area that is geographically defined.
Furthermore, investigating theological positional changes in health risks is also possible. GIS is used in following and
analyzing events related with health, such as disease outbreaks. In addition, mapping diseases, geographical correlation studies, environmental risk evaluation, and the health compilation of applications can be conducted with GIS (3).
The aim of this study is to study the causes and range of deaths of children under the age of 5 years in counties
of İstanbul; the other aims are to spatially determine the socioeconomic range, investigate the piling up of Z value
death rate in towns, and compare the educational level and age-specified death rates to investigate GIS as a critical
tool in analyzing community health and in creating health plans and programs.
