Introduction:
Infant Mortality Rate (IMR) is the number of deaths of infants under one year of age per 1000 live births. It is an important indicator of the health and well-being of a population.

Explanation:
Kerala is the state in India with the lowest Infant Mortality Rate. According to the latest data from the Sample Registration Survey (SRS) released by the Registrar General of India, the IMR in Kerala is 7 per 1000 live births, which is much lower than the national average of 32.

Reasons for low IMR in Kerala:
1. High literacy rate: Kerala has one of the highest literacy rates in India, which means that people are more aware of health and hygiene practices. This leads to better maternal and child health outcomes.

2. Access to healthcare: Kerala has a well-developed healthcare system with a high density of hospitals, clinics, and primary health centers. This ensures that pregnant women and infants have access to quality healthcare services.

3. Focus on maternal and child health: The government of Kerala has implemented various programs and policies to improve maternal and child health. For example, the Janani Suraksha Yojana provides financial assistance to pregnant women for delivery and post-natal care.

4. Nutritional status: Kerala has a relatively high per capita income, which means that people have better access to nutritious food. This contributes to better maternal and child health outcomes.

Conclusion:
In conclusion, Kerala has the lowest Infant Mortality Rate in India due to its high literacy rate, access to healthcare, focus on maternal and child health, and nutritional status. Other states can learn from Kerala's success and implement similar policies and programs to improve maternal and child health outcomes.

Kerala has low infant mortality rate because it mainly concentrates on human resource development.
