Vital Statistics

Concept: Crude Birth Rate (CBR) and Crude Death Rate (CDR) are calculated as the number of births or deaths per 1000 population per year.
Given:

Total population = 1,20,000
Number of births = 1,500
Number of deaths = 1,200


Step 1: Calculate CBR

Step 2: Calculate CDR
Final Answers:

Crude Birth Rate (CBR) = 12.5 per 1000 population
Crude Death Rate (CDR) = 10 per 1000 population

Concept: Neonatal Mortality Rate (NMR) is the number of deaths of infants within the first 28 days of life per 1000 live births in a given year.
Formula:
Given:

Live births = 4,000
Neonatal deaths = 100


Step 1: Substitute values into the formula

Step 2: Calculate
Final Answer:

Concept: Both Neonatal Mortality Rate (NMR) and Infant Mortality Rate (IMR) are indicators of child health and healthcare quality, but they differ based on the age group considered.

Explanation:
Neonatal Mortality Rate (NMR): It measures deaths occurring within the first 28 days of life. It mainly reflects the quality of prenatal care, childbirth practices, and immediate postnatal care.
Infant Mortality Rate (IMR): It includes all deaths of children before completing one year of age. It reflects overall healthcare, nutrition, sanitation, and immunization.
