Q

• attempts to enumerate every person in a country. However, in contrast to vital statistics data, which are typically collected continuously and summarized on an annual basis, censuses typically occur only every 10 years or so and thus are not usually the best source of data on births and deaths.

20
Q

the annual number of live births per 1,000 people.

A

crude birth rate,

21
Q

the annual number of live births per 1,000 women of childbearing age (often taken to be from 15 to 49 years old, but sometimes from 15 to 44).

A

general fertility rate

22
Q

the annual number of live births per 1,000 women in particular age groups (usually age 15-19, 20-24 etc.)

A

age-specific fertility rates

23
Q

the annual number of deaths per 1,000 people.

A

crude death rate

24
Q

the annual number of deaths of children less than 1 year old per 1,000 live births.

A

infant mortality rate

25
Q

the number of years that an individual at a given age could expect to live at present mortality levels.

A

expectation of life

26
Q

the number of live births per woman completing her reproductive life, if her childbearing at each age reflected current age-specific fertility rates.

A

total fertility rate

27
Q

is the average number of children a woman must have to replace herself with a daughter in the next generation.

A

replacement level fertility

28
Q

the number of daughters who would be born to a woman completing her reproductive life at current age-specific fertility rates.

A

gross reproduction rate

29
Q

the expected number of daughters, per newborn prospective mother, who may or may not survive to and through the ages of childbearing.

A

net reproduction ratio

30
Q

one that has had constant crude birth and death rates for such long time that the percentage of people in every age class remains constant, or equivalently, the population pyramid has an unchanging structure.

A

stable population

31
Q

one that is both stable and unchanging in size (the difference between crude birth rate and crude death rate is zero).
- A stable population does not necessarily remain fixed in size, it can be expanding or shrinking

A

stationary population

32
Q

Populations can change through 3 processes:

A
  1. fertility
  2. mortality
  3. migration
33
Q
  • involves the number of children that women have and is to be contrasted with fecundity (a woman’s childbearing potential).
A

Fertility

34
Q

study of the causes, consequences, and measurement of processes affecting death to members of the population.

A

mortality

35
Q
  • refers to the movement of persons from an origin place to a destination place across some pre-defined, political boundary
    • Migration researchers do not designate movements ‘migrations’ unless they are somewhat permanent.
    • Thus demographers do not consider tourists and travelers to be migrating.
    • While demographers who study migration typically do so through census data on place of residence, indirect sources of data including tax forms and labor force surveys are also important.
A

• Migration

36
Q

t or f

One method of measuring the population size is by determining the increase in the population resulting from excess of births compared to deaths.

A

true

37
Q

simply the difference between the number of births and the number of death occurring in a population in a specified period of time

A

Natural increase

38
Q

number of births - number of deaths (specified year)
(specified year)
(specified year)

A

Natural increase

39
Q

is the difference between the CBR and the CDR occurring in a population in a specified period of time
• Rate of Natural Increase = Crude Birth Rate - Crude Death Rate (specified year)
(specified year)
(specified year)

A

Rate of Natural increase

40
Q

measurements the number of people that are added to the population per year.

A

Absolute increase per year

41
Q

Absolute increase per year = pt-po/t

Pt= Population size at a late time
Po= Population size at an earlier time
t= number of years between time 0 and the time

A

formula of Absolute increase per year

42
Q

Is the actual difference between the two census counts expressed in percent relative to the population size made during an earlier census.

A

Relative increase

43
Q

Relative increase= Pt-po/po

Pt= population size at a later time
Po= population size at an earlier time

A

Relative increase

44
Q

is commonly described in terms of its age and
• The PHW utilizes data on age and sex composition to decide who among the population groups merits attention in terms of health services and programs.

A

Population Composition

45
Q

To describe the sex composition of the population, the nurse computes for the sex ratio. The sex ratio compares the number of males to the number of females in the population using the formula below

A

Sex composition

46
Q

t or f
sex ratio= number of males/ number of females x 1000

sex ratio represents the number of males for every 1, 000 females in the population.

A

true

47
Q

There are two ways to describe the age composition of the population.

  • divides the population into two equal parts.
  • So, if the median age is said to be 19 years old, it means half of the population belongs to 19 years and above, while the other half belongs to ages below 19 years old.
A

Median age

48
Q

There are two ways to describe the age composition of the population.

  • compares the number of economically dependent with the economically productive group in the population.
  • economically dependent are those who belong to the 0-14 and 65 above age groups.
  • considered to be economically productive are those within the 15- 64 age group.
  • The dependency ratio represents the number of economically dependent for every 100 economically productive.
A

Dependency ratio

49
Q

The age and sex composition of the population can be described at the same time using a population pyramid.
It is a graphical presentation of the age and sex composition of the population.

A
  1. Age and Sex composition
