Study Notes
Vital Statistics Overview
- Vital statistics address key life events: births, deaths, and morbidity.
- Registered data provide vital rates, indicators of population health and community development.
- Important for assessing vulnerable groups and socioeconomic factors influencing health.
Birth Rate
- Defined as the number of live births per 1,000 population within a specific locality and year.
- Calculated using the formula:
- Birth Rate = (Number of live births / Midyear population) × 1000
Fertility Rates
- Measures live births specifically among married women of childbearing age in a given locality and year.
- General Fertility Rate (GFR):
- Calculates live births per 1,000 females in the childbearing age (typically 15-49).
- Formula:
- GFR = (Number of live births / Number of females in childbearing period) × 1000
Age-specific Fertility Rate
- Reflects total fertility for specific age groups within the childbearing period (15-49).
- Involves seven 5-year age brackets to summarize total fertility across different age ranges.
Prevalence Rate
- Indicates existing cases of a disease within a population at a specific time.
- Calculated with the formula:
- Prevalence Rate (P) = (Number of people with the disease / Number of people at risk) × 10^n
Incidence Rate
- Represents the rate of new cases occurring during a defined period in a specified population.
- Calculated as:
- Incidence Rate (I) = (Number of new cases / Number of persons exposed to risk) × 10^n
Case-fatality Rate
- Measures fatalities due to a specific disease, expressed as deaths per 100 cases within a locality and year.
- Formula:
- Case-fatality Rate = (Number of deaths / Number of reported cases) × 100
Mortality Rate
- Specifies deaths from a particular disease per 100,000 population in a given year and locality.
- Proportionate Death Rate indicates the percentage of deaths from a specific disease relative to total deaths.
General Death Rate
- Represents all-causes mortality across all ages, calculated using:
- Crude Death Rate = (Total number of deaths / Midyear population) × 1000
