Infant mortality is the death of infants in the first year of life. The leading causes of infant mortality are dehydration and disease. Major causes of infant mortality in more developed countries include congenital malformation, infection and SIDS.

Infanticide, abuse, abandonment, and neglect may also contribute to infant mortality.

• Perinatal mortality only includes deaths between the foetal viability (28 weeks gestation or 1000g) and the end of the 7th day after delivery.
• Neonatal mortality only includes deaths in the first 27 days of life.
• Post-neonatal death only includes deaths after 28 days of life but before one year.
• Child mortality includes deaths within the first five years.

Infant mortality rate (IMR) is the number of newborns dying under a year of age divided by the number of live births during the year. The infant mortality rate is also called the infant death rate. In past times, infant mortality claimed a considerable percentage of children born, but the rates have significantly declined in the West in modern times, mainly due to improvements in basic health care, though high technology medical advances have also helped. Infant mortality rate is commonly included as a part of standard of living evaluations in economics.

The infant mortality rate corrolates very strongly with and is the best predictor of state failure.

Infant mortality rate is reported as number of live newborns dying under a year of age per one thousand live births, so that IMRs from different countries can be compared. A good source for the most recent IMR's as well as under 5 mortality rates (U5MR) is the UNICEF publication 'The State of the World's Children' available at http://www.unicef.org/publications/index_18108.html For example, the worst U5MR is 284 in Sierra Leone. (That's 28% of all children born die before they turn 5 years old.) The 29 countries with the highest U5MR are in Africa. The U5MR of the United States is 8/1000, and there are 31 countries with lower U5MRs. Sweden's is the lowest at 3.

Comparing statistics for IMR across countries can be a useful indicator of their level of health and development, but the method for calculating IMR often varies widely between countries based on the way they define a live birth. The World Health Organization defines a live birth as any born human being who demonstrates independent signs of life, including breathing, muscle movement, or heartbeat. Many countries, however, including certain European states and Japan, only count as live births cases where an infant breathes at birth, which makes their reported IMR numbers somewhat lower and raises their rates of perinatal mortality.

The most common cause of IMR of all children around the world has traditionally been dehydration from diarrhea. Because of the success of spreading information about Oral Rehydration Solution (a mixture of salts, sugar and water) to mothers around the world, the rate of children dying from dehydration has been decreasing and has become the second most common cause in the late 1990s. Currently the most common cause is pneumonia.
