Uses of demo 4

1. Sex Ratio 2. Sex Structure

A. Sex Composition

Enumerate

1. Median Age 2. Dependency Ratio

Age Composition

Enumeration

Sex Ratio

• Compares the number of males to the number of females

Sex ratio formula

Sex Structure

• Compares the sex ratio across different categories/levels of another characteristic

Median Age

• The value which cuts-off the upper 50% and lower 50% of the ages of the population.


Median age

• Used to gauge whether the population is young or old

Age-Dependency Ratio

The computed value represents the number of dependents that need to be supported by every 100 persons in the economically-active groups.

Def

Age dependecy ratio formula

Population Pyramid

• Also enables one to explain and describe the demographic trends of the population in the past.

Population Pyramid

• A graphical presentation of the age and sex composition of the population

Stage 1 - rapid expanding

High birth rate; rapid fall in each upward age group due to high death rates; short life expectancy

Pop pyramid

Stage 2 - expanding

High birth rate; fall in death rate as more living in the middle age; slightly longer life expectancy

Pop pyramid

Stage 3 - stationary

Declining birth rate; low death rate; more people living to old age

Pop pyramid

Stage 4 - contracting

Low birth rate; low death rate; higher dependency ratio; longer life expectancy

Pop pyramid

HEALTH INDICATORS

Quantitative measures


HEALTH INDICATORS

Uses of health indicators

Crude Birth Rate (CBR)

• Measures how fast people are added to the population

GFR = 200 l.b./1000 pop/yr

^ fertility rate

GFR low fertility rate

GFR = 60 l.b./1000 pop/yr

v fertility rate
