Infant mortality rate (IMR) is a measure denoting the total number of less-than-a-year-old infants’ deaths for every 1000 births in a particular year.

IMR Statistics

On an average, during the 1990s, there were 61 infant deaths for every 1000 births in developing nations; 8 deaths were registered for every 1000 births in developed countries. The rate has now (2015) come down to 32 deaths. Also, the mortality rate is likely to be 100 deaths for every 1000 births among mothers not older than 20 years, in comparison to 70-odd deaths for older women.

IMR experienced among women in their 40s is usually 94 per 1000 births, quite close to teen mom rates. Older mothers are invariably at the far end of their reproductive years. These women are also likely to be malnourished due to poverty or the toll their body has taken over the years due to frequent childbearing.     

IMR helps measure a city, state or country’s health levels. The lower the number, the healthier is the region. The rate is typically lower in developed countries than developing nations, thanks to the better health and medical conditions of the former.
