(Fertility & Morbidity) Rate

Fertility:• Crude Birth Rate (CBR) - Overall total reported

births,

Morbidity-Illnesses affecting the population group• Incidence Rate (IR): reported new cases

affecting the population group• Prevalence Rate (PR): determine sum total of

new + old cases of diseases per percent population

Mortality Rate

Mortality-Reports causes of deaths• Crude Death Rate (CDR)-overall total reported death• Maternal Mortality Rate (MMR)-maternal deaths due

to maternal causes• Infant Mortality Rate (IMR)-# of infant deaths (0-12

months) or less than 1 year old• Neonatal Mortality Rate (NMR)-# of deaths among

neonates (newborn 0-28 days, < 1 month)• Swaroops Index (SI)-deaths among individual in the

age group of 50 and above
