Vital Statistic Definition:Statistics concerning the importantevents in human life, such as births,deaths, marriages, and migrations.
Important:Knowing the health status, used as baseline data for planning, development ofhealth services in the future. History:Early in Egypt, Palestine, Babilonia, Rome& China 1860 (17%) 1974 (55%)

Measurements of the changes, estimatesand projections of populationimportant to know
The population denominator used as atool in the rate or ratio is important inexplaining the events that occur insociety
Census population still government'sresponsibility

1. Crude Death RateThe total number of deaths during the year
divided by mid-year population in a country
The total number of deaths during the year
CDR = ------------------------ x 1000
Midyear population

2. Specific Death Rate\
Mortality was directed at the cause of death(diarrhea, tetanus, etc.) or community groups (age,
sex, occupation, etc.) or a period of time (days,weeks, months, etc.)
Number of Deaths by specific cause
SPD(*) = ------------------------------ x 1000Midyear population
(*) = Therefore certain

3. Crude Live Birth Rate = CLBR
The total number of live births divided by the
population mid-year
The total number of live births
CLBR = -------------------------- x 1000
Midyear populations

1. When obtained the total population onJanuary 1 (P1) and December 31 (P2) in thesame year, the total population at mid-year=
(P1 + P2) P1 + (P2-P1)--------- or -----------

3. When mid-year population desired is locatedbetween two census then calculated using theformula:
P1 + n
P = -----------------------N (P2 - P1)
P = Mid-year population desiredP1 = The population at the first censusP2 = The population on which the second censusn = Number of months between the first and mid-year census desiredN = Number of months between 2 census

1. Natural Increase:
The rate of natural increase(RN
) is the crude birth rateminus the crude death rate of apopulation (excluding migration)
Natural Increase rate = CLBR - CDR

2. Relative Increase in Population Size(RI):
Addition of the population is calculated basedon a percentage of the population now
compared to the population of the past.Pt - Po
RI = ----------- x 100%
Po
Pt = The population nowPo = Number of past population
11

3. Absolute Increase in Population Size (b) :Addition of the population is calculated basedon population now reduced the number ofpeople past, divided by the length of running
time Pt - Po
b = ------------
t
Pt = The population now;Po = Number of past population;t = time (year)

1. Component Method:By way of calculating the components of
natural increase is added to the process ofpopulation migration.
Pt = Po + EPt = The population now;Po = Number of past population
E = (The number of births - Number of deaths) + (Immigrant Emigrant)

2. Mathematical Methoda. Arithmetic Method: Assuming that the absolute
popu lation increase is approximately the sameeach year
Pt = Po + btb. Geometric Method: Assuming that the
percentage of increase or reduction in thepopulation or the percentage growth inpopulation is always constant and takes placeevery year
Pt = Po (1 + r)tPt = The population now;Po = Number of past populationb = Absolut increase of population size
r = Constant rate of growths (%);t = time (year)

c. Exponential Method : Assuming that thepercentage of increase or reduction inpopulation is always constant in amathematical and takes place every year.
Pt = Po x e rt
Pt = The population now;Po = Number of past population
b = Absolut increase of population size
r = Constant rate of growths (%)
e = Mathematical constant = 2,718

Sex Ratio: Comparisons between the totalpopulation of men and women
Total population of men
Sex Ratio = --------------------- x 100
Total population of women

Dependency Ratio: ratio between the numberof non-productive age population (0-14years and> 65 years) and productive (15-64years) evaluated from the economy
number of non-prod age pop
D. Ratio = ----------------------- x 100
number of productive age pop

The form of a pyramid
diagram that illustrates thecomposition of population
by age group and sex
