Vital Statistics

• Vital Statistics 


  Systematic study of vital events (births, marriages, etc)
• Crude birth rate


  Also known as natality rate
• Crude birth rate


  Measures natural increase of population
• Growing population: Crude birth rate exceeds the Crude death rate
• Crude birth rate

  (Total birth/Total Population) x 1000
• Crude death rate


  Measures the natural decrease of population
• Declining population: Crude death rate is greater than the crude birth rate
• Crude death rate

  (Total death/Total Population) x 1000
• Maternal Mortality Rate


  Index of prenatal care in the community e.g. prenatal visit
• Maternal Mortality Rate

  (Total death due to pregnancy/Total live births) x 1000
• Neonatal Mortality Rate


  Index of postpartum care (1st month of life) in the community; BOTH mother & baby are assessed
• Neonatal Mortality Rate

  Postpartum checkup are done twice: within 24 hrs, within 1 week after delivery
• Neonatal Mortality Rate

  (Total death below 28 days/Total live births) x 1000
• Infant Mortality Rate


  (1st year of life) Index of the health status of the whole community; MOST IMPORTANT
• Infant Mortality Rate

  (Total death below 1 year /Total live births) x 1000
• Fetal Death Rate


  Index of pregnancy wastage
• Fetal Death Rate

  (Total death intrautero/Total live births) x 1000
• Incidence rate


  Measures Acute Diseases (less than 6 mos); New
• Incidence rate

  (Total # of new cases/Total Population) x 1000
• Prevalence Rate


  Measures Chronic Diseases; old + new cases
• Prevalence Rate

  (Total # of old & new cases/Total Persons Examined) x 100
• Sex Ratio


  Measures balance of male over female
• Sex Ratio

  (M/F) x 100
• Swaroop’s Index


  Measures longevity of life; “healthy lifestyle”
• Swaroop’s Index

  (Total Death >50y.o./ Total Death) x 100
• Swaroop’s Index

  SI: >80 above = GOOD
