Q

DESCRIBING THE POPULATION DISTRIBUTION

A
  1. Urban-Rural Distribution
  2. Crowding Index
23
Q

can be computed by dividing the total number of persons in the household by the number of rooms in the house.

A

Crowding Index-

24
Q

difference between the number of births and the number of deaths which occurred in a specific population within a specified period of time.

A

Natural Increase

25
Q

measure that is the result when the natural increase is expressed relative to the population size. It represents the difference between the Crude Birth Rate and the Crude Death Rate of a specific population within a specified time period.

A

Rate of Natural Increase

26
Q

measures the average number of people added to the population per year.

A

Absolute Increase per year

27
Q

Absolute increase per year (b)=

A

Population size at a latter time – Population size at an initial time / Number of years between initial time and latter time

28
Q

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

A

Relative Increase

29
Q

Relative increase=

A

Pt-Po / Pox 100

30
Q

also known as inflow-outflow or the balancing equation method.

A

Component Method-

31
Q

Pt=

A

Po + (B+D) + (I+D)

32
Q

B=

A

number of births occuring during the interval o and t

33
Q

D=

A

number of deaths occuring during the same interval

34
Q

I=

A

number of in-migrants between time o and t

35
Q

O=

A

number of out-migrants between time o and t

36
Q

classified into 3 subtypes depending on the assumption that one wishes to make with regard to the nature of the population growth that occurs.

A

Mathematical Method-

37
Q

assumes that an equal amount of absolute change occurs in the population every year

A

Arithmetic method

38
Q

assumes that a constant rate of increase or decrease occurs over each unit of time, usually a year.

A
