DEMOGRAPHY Flashcards
(51 cards)
is the statistical study of human
population.
* It encompasses the study of the size,
structure and distribution of populations
* spatial and/or temporal changes in
response to birth, migration, aging and
death
Demography
study of the character,
number, and distribution of living
organisms residing in or migrating
through particular places
POPULATION
*Social and Biological Science
*Size of Breeding Group
FACTORS IN POPULATION
- The computation of vital and health
statistics rates and ratios. - Setting up coverage of activities.
- Setting up norms for assignment of
health facilities, staff and funds.
three principal uses of
population data in health administration,
- Continuous Population Registration
- Consist of registering births, deaths,
emigration and immigration, making
necessary additions and subtractions to
the existing population.
Estimates of Population Size
Simple way of estimating the
number of population in a smaller area
Surveys
assumed that the population increases at
a constant amount per year
Arithmetic Increase Method
assume
that population increases at a constant
rate per year
Geometric Increase Method-
applied to whole societies or to
groups defined by criteria.
– education, nationality, religion and
ethnicity.
Demographic analysis
–limits its object
of study to the measurement of
populations processes
Formal demography
population
studies analyze the relationships between
economic, social, cultural and biological
processes influencing a population
Social demography
encompasses the
study of fertility, mortality and migration.
Population studies
the common direct method
of collecting demographic data.
* conducted by a national government
and attempts to enumerate every person
in a country.
CENSUS
official and
periodic enumeration of population
Census
collected
continuously and summarized on an
annual basis
Vital statistics data
done when people
are assigned to the place where they
usually live regardless of where they are
at the time of census
De jure method
done when the
people are assigned to the place where
they are physically present at the time of
the census regardless of their usual place
of residence
De facto method
obtained data come
from a small number of people
proportionate to the total population, –the
results will always be generalized for the
whole population
Sample Survey
collected by
the civil registrar’s office deal with
recording vital events in the community
Registration systems
refer to births, deaths,
marriage, divorces and the like
Vital events
collect information about
families or households
– characteristics as age, sex, marital
status, literacy/education, employment
status
Censuses
Two methods of data collection:
Direct and indirect data collection:
come from vital statistics
registries that track all births and deaths.
- changes in legal status (marriage,
divorce) - migration (registration of place
of residence).
Direct data
collecting data are
required in countries where full data are
not available.
Indirect methods
