Infant mortality is still a big problem for people living in developing countries. Not only the developing countries, but this issue is also present globally. It is one of the indicators for the quality of health in a country. Therefore, the governments try to reduce it by increasing the primary care facilities in the country. Considering the importance of the topic, we have decided to research the factors that impact the infant mortality rate globally.

Many factors affect the infant mortality rate of a country. The dependent variable, in this case, will be the mortality rate, infant (per 1,000 live births) which is defined by the World Bank as the number of infants that die before reaching the age of one. Multiple independent variables can be used for this research. These include:

• Healthcare expenditure, defined as the total public and private healthcare spending in a country
• Adolescent fertility rate (births per 1,000 women ages 15-19)
• Immunization, measles (% of children ages 12-23 months)
• Improved sanitation facilities (% of the population with access)
• Prevalence of undernourishment

Research Question: Is there a linear relationship between the expenditure on health care and the Infant Mortality Rate or which indicators can predict the Infant Mortality Rate best?
