What is development and how is it measured?
The Geography of development is all about how wealth and the quality of
life of people living on our planet varies from place to place. We can
study this on a local scale, and consider with our own community how
different groups of people on one estate might be wealthier and have a
better quality of life than others. We could look at development a
national scale, and consider how health and wealth change across the
British Isles (life
expectancy is lower in Scotland than it is in England for example).
The last scale we can look at is globally, because there are huge
differences between the quality of life between countries and
continents. There are
2 very
broad groups of countries;
More Economically Developed Countries or MEDCs
Less Economically Developed Countries or LEDCs
There are a huge number of measures that can be used to measure the
level of Development of a place.
These measures can be classified as Social – relating to the
development of the people of the place; Economic, relating to the
finances and wealth of the place; and Political, relating to the
political systems and freedoms afforded by the place.
Some countries may have imbalances in these measures, so a
country may have very high levels of wealth and economic development,
but poor levels of political freedom so poor political and social
development.
It is therefore better to look at a NUMBER of different
measures of development of places before coming to a judgment about its
level of development.
The most powerful individual number or measure is probable the
Human Development Index, because it combines together economic and
social measures into one figure.
However, I quite like the
Happy Planet
Index as an alternative! Surely if people are ranked as happy then
their country or region is developed!
The Exam board expects you to know the definitions below, but there are
many other Indicators of development that you could investigate;
1.
GNP -Gross National Product
– how much money a country earns as a population excluding business
taxes.
This is a total sum, and shows the overall size of the
economy.
We need to be very careful when using this measure, as it does
not take into account population size as shown in the example below.
Brazil and the UK have very similar GNPs in 2011, but the UK
is much richer per person as it has a smaller population.
2. GNI per head - Gross national income is a measure of the country’s wealth. GDP is part of GNI. It includes the total value of goods and services produced within a country (i.e. its Gross Domestic Product), together with its income received from other countries (such as interest and dividends), minus similar payments made to other countries. So if a British-based company such as BP sends profits back to the UK our GNI is enhanced, whilst profits flowing out of the country from a company such as Nissan to Japan will count to Japan’s GNI and not the UKs. GNI is therefore different to GDP because it includes it!
3.
Human Development Index (HDI)
– This is a composite (combined) measure that considers life
expectancy, GNI and an education index to give a value between 0 and 1,
1 being the most developed.
This is powerful as it includes both economic and social
factors.
4.
Birth Rates
-
How many babies are born per 1000 people in a population per year.
We tend to find that the poorest countries have high birth
rates, and wealthier countries have lower births rates.
This is because poorer countries have high replacement rates
to compensate for high infant mortality, poorer access to family
planning and contraception, and a tradition for large family size to
supplement a largely agricultural workforce.
5.
Death rates
-
How many people die per 1000 people in a population per year.
This is becoming less useful as a measure of development, as
death rates fall due to imported medicine and technology in many poorer
countries.
It would be better to look at CAUSE of death, as in MEDCs it
will be wealth and age related illnesses
6.
Infant mortality
- How many babies die per 1,000 live births per year.
This is a useful measure as it indicates the medical systems
in the country and how well the most vulnerable in society, the very
young, are protected and looked after in their early years.
7.
People per doctor
- How many people there are for every doctor in a country or place.
Again, this indicates how much money is available in a country
for the training and recruitment of doctors, which has an instant knock
on effect on the well-being and quality of life of a person.
8.
Literacy rate
- What percentage of the country is able to read and write as adults.
This is another social measure, and helps to indicate the
standard of education within a country or place.
9.
Access to safe water
- What percentage of people have access to sanitary and safe water
that is free from bacteria and parasites.
This is something we take for granted in the UK, but according
to
Water.org
780 million people lack access to safe water and 3.4million die every
year from a water related disease.
10.
Life expectancy
- The average age a person can expect to live to at birth.
This is a very useful indicator as it reveals how good food
security, water quality, shelter and medical care are in a country.
