Transcript of Demographic Transition
By: Mayelin Taveras
: Low Growth
: High Growth
: Moderate Growth
: Low Growth
In the beginning of the world's population there was barely any growth. During the agricultural revolution, humans began to domesticate plants and animals they were no longer hunting. Due to high death and birth rates the NIR was equal to zero.
lasted for quite sometime it was not until 1750 when all the countries were at least in stage 2.
The world began to grow about 5 million a year verses in previous years (1750 and before) just half a million. The world population grew from 0.05% to .50% to then 1% and so on.
1880- Early 1970's
The transition began in Europe and North America in 1900s,
between stage two to
occurs when the CBR drops sharply. The CDR falls at a slower rate the population still grows because the CBR is greater than the CDR .
A country tends to enter
because people are choosing to have less children. People are typically much more advanced during this stage. Large families are no longer needed for farming children have grown to become more expensive .
Early 1990's- Present
With the Industrial Revolution major improvements occurred: cleaner water systems, cities grew, agriculture increased became faster, advancement in medicine took place as well. Less people were now dying. The CDR decreased, CBR remained about the same an increase in population (NIR).
led to less deaths due to medical advances.
A country reaches
when the demographic transition CBR declines to the point where the CDR and NIR approaches zero. Zero population growth is known as ZPG.
The immigrants that are moving in do not count as that country increase in population. This mostly occurs in European countries with exceptions of a few others Usually, social customs explain one movement to another.
The beginning man-kind was considered was
. Some consider it as the Flintstones era because this was when
was humans hunting and using their natural resources provided to them. Until 1750 when other countries were beginning to be discovered.
Usually, less developed countries are in this stage for example several African countries remain in stage two. With very little to prevent less pregnancy and less education most African countries (ex. Kenya) fail to move forward to stage 3.
Countries like Indonesia, India and Pakistan are examples of stage three, because of the low death rates yet higher birth rates are all present. In today's world the factors like religion will be more important than the traditional concept large groups will know be able to know the options, but the individual change of behavior will have to progress from a peer pressure to an individual choice.
Today, European countries are mainly in stage four. England is a prime example, of a country that has gone through all four stages and who is currently at its fourth stage. The TFR is extremely low England has had very little population growth.
Stage Five is still not determine a few countries that are in stage four may move into stage five. It is not certain when and it is not certain how stage five will be like. Many predict that it will be anther plague or epidemic that will occur to cause more death rates or a lower amount or birth rates as well.
