Module 2 (Prelim) Flashcards
Study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations.
demography
Sources of demographic data
census, sample survey, registration system, studies and research
Official periodic complete enumeration of the population
census
Collected from a sample of a given population
sample survey
Data is from a small number of people; results will always be generalized or the whole population
sample survey
Collected by the civil registrar’s office-record designed to count vital events in the community
registration system
Births, deaths, marriages, divorces, and entries and exits at international boundaries
registration system
Refer to the number of people in a given space/area at a given time
population size
methods of measuring population size
excess of birth compared to death, data obtained during the 2 census period, population composition
Commonly describe in terms if its age and sex
population composition
The nurse utilizes age and sex composition to decide who among the population groups merits attention in terms of health services and programs.
population composition
Formula for sex ratio
of males/# of females (100)
Two ways to get age composition
median age, dependency ratio
Divides the population into 2 equal parts
median age
Compares the # of economically dependent with the economically productive group in the population
dependency ratio
Can be described at the same time using a population pyramid
age and sex composition
Helps decide how meager resources can be justifiably allocated based on the concentration of population in an area.
population distribution
Used to describe urban-rural population distribution
population distribution
2 ways to determine population distribution
crowding index, population density
Describes the case by which communicable diseases will be transmitted from one to another
crowding index
Determines how congested a place is and provides implications in terms of adequacy of basic health services presented in the community.
population density
Tool in estimating the extent or magnitude of health needs and problems in the community.
vital statistics
Through this ______ the nurse is able to describe the health status of the people which serves as the basis for developing, implementing, and evaluating programs and intervention strategies.
vs indicators
Health statistical indicators
CBR, CDR, IMR, MMR, SMR, life expectancy, health profile
It is the annual number of live births per 1,000 population
crude birth rate
Numerator: number of live births observes in a population during reference period
Denominator: number of person-years lived by the population during the same period
crude birth rate
It is called “crude” because it does not take into account age or sex differences among the population
crude birth rate
More than 30/1,000 is considered high, rates of less than 18/1,000 are considered low
crude birth rate
