define demography
statistical or scientific study of human population
define population
grp of individuals of the same species in the same geographical area at at the same time
what are the different aspects of human populations
size
distribution
composition
population dynamics
identify the aspect of human populations in demography:
study of change of the people or the population in size or structure
population dynamics
identify the aspect of human populations in demography:
number of people in a geographic area at a certain time
size
identify the aspect of human populations in demography:
the number of people in age, sex, or other demographic quantities or categories
composition
identify the aspect of human populations in demography:
way of dispersion of people in geographic location at a certain time
distribution
what are the sources of demography
census
registration of vital events
sample surveys
census is the entire process of ___, ___, ___, ___, ___, ___, data to the people
collecting
compiling
evaluating
analyzing
publishing
disseminating
it is defined as an enumeration or complete population count at a point in time within a specified geographical data
census
what are the 2 techniques of conducting census
dejure
defacto
identify the census technique:
this technique is counting of people according to the permanent place of location or residences
dejure
identify the census technique:
this technique of conducting census refers to counting of persons where they are present at the time of the census period
defacto
which census technique is the realistic and more useful statistics
dejure
what is the disadvantage of using defacto technique
gives disadvantage of people who like to travel
it refers to the civil registration system, which records births, deaths, marriages etc. (vital statistics), enables rates of population growth to be calculated
registration of vital events
this carried out in a scientifically selected area which covers only a section or portion (sample) of the population under consideration
sample survey

what are the demographic measurement tools
ratio
proportion
rate
identify the demographic measurement tools:
there is a quotient of 2 demographic quantities
ratio
identify the demographic measurement tools:
numerator always part of denominator
proportion
identify the demographic measurement tools:
always in percent (x100)
proportion
identify the demographic measurement tools:
a type of ratio which indicates the relation in magnitude of a part of the whole
proportion
identify the demographic measurement tools:
the only tool that includes time
rate
what are the 4 elements of rate
denominator
numerator
constant / multiplier
Time
what are the composition of population
YEARS PROML
year of birth
education level
age
religion
place of birth
race
occupation
martial status
language
define age composition
distribution of age by the population
age composition is also known as the
age structure
age distributor
which age group is the active population
15-64 years old
age group 15-64 is considered ______ active
economically
dependent population is also known as the ______ population
inactive population
which age group is the dependent population
0-14 and 65+
active population -
inactive population -
adult
young and old
it measures the size of the dependent population relative to the independent
proportion
define labor force ratio
regardless of age as long as the person is capable to work
what can you infer if there is a decrease in young people and increase in old age
increase life expectancy
what is the average life expectancy
60 because of lifestyle
what can you infer if the young people increase
increase in fertility rate
age that divides a population into
two numerically equal groups - that is, half the people are younger than this age and half are older
median age
in sex ratio,
if there is an increase in sex ratio =
many man
what is the formula of sex ratio
male population/ female population x100
what are the classification of sex ratio
pri sex ratio
sec sex ratio
tertiary sex ratio
identify the classification of sex ratio:
ratio of fertilization, sex ratio of unborn offspring, ratio at the time of just conception
pri sex ratio
identify the classification of sex ratio:
ratio at the sexualhood
tertiary sex ratio
identify the classification of sex ratio:
ratio at the time of birth
sec sex ratio
what is the sex ratio in the Philippines
103 males per 100 female
range for sex ratio:
if above 100 =
if below 100 =
excess of males
excess of females

65+:
pre -reproductive
reproductive
post-reproductive
what are the 3 types of population pyramid and its shape
expanding population - triangular shape
declining population - urn-shaped
constant population - rectangular shape
in declining population, it has equal ____ and ____ rate, lower life expectancy
death
birth
identify the type of population pyramid:
lower life expectancy -
decreasing life expectancy -
Declining population
Constant population
what are the factors affecting the population size and age
fertility rate
mortality rate
dependency and labor force ratio
define population density
no. of species members within a defined geogrphic boundary
define population growth rate
no. of individuals in relation to time
change in the no. of individuals over a specific period can be attributed to 3 factors (population growth rate)
birth rate
death rate
migration
high death rate =
high birth rate =
population decline
