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 -----------

2. When obtained the total population of March1 (P1) and December 31 (P2) in the sameyear, the total population at mid-year (P):

P = P1 + ------ x P2

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

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
