2 What is the Demographic Transition Model (DTM)? The demographic transition model explains the transformation of countries from having high birth and death rates to low birth and death rates.In developed countries this transition began in the 18th century and continues today.Less developed countries began the transition later and many are still in earlier stages of the model.
3 Task One10 minutesMake a copy of the DTM in your books, across a double page.Make sure you add appropriate labels/detail.
4 Stage OneBirth Rate and Death rate are both high. Population growth is slow and fluctuating.Birth Rate is high because of:Lack of family planningHigh Infant Mortality Rate: putting babies in the 'bank'Need for workers in agricultureReligious beliefsChildren as economic assetsDeath Rate is high because of:High levels of diseaseFamineLack of clean water and sanitationLack of health careWarCompetition for food from predators such as ratsLack of educationTypical of Britain in the 18th century and the Least Economically Developed Countries (LEDC's) today.
5 Typical of Britain in 19th century; Bangladesh; Nigeria Stage TwoBirth Rate remains high. Death Rate is falling. Population begins to rise steadily.Death Rate is falling as a result of:Improved health care (e.g. Smallpox Vaccine)Improved Hygiene (Water for drinking boiled)Improved sanitationImproved food production and storageImproved transport for foodDecreased Infant Mortality RatesTypical of Britain in 19th century; Bangladesh; Nigeria
6 Typical of Britain in late 19th and early 20th century; Stage ThreeBirth Rate starts to fall. Death Rate continues to fall. Population rising.Reasons behind birth and death rate falling:Family planning availableLower Infant Mortality RateIncreased mechanization reduces need for workersIncreased standard of livingChanging status of womenTypical of Britain in late 19th and early 20th century;China; Brazil
7 Typical of USA; Sweden; Japan; Britain Stage FourBirth Rate is low.Death Rate is low.Population steady.Typical of USA; Sweden; Japan; Britain
8 Stage Five Typical of Germany Birth Rate slight fall. Death Rate stable.Natural increase: gentle decreaseReasons for changes in birth rate:Family planningBetter healthLater marriagesImproved status of womenReasons for changes in death rate:Good health careReliable food supplyPeople are generally living longer
9 What are the limitations? What limitations do you think there could be with the model?It does not include the influences of migrationIt assumes that all countries will go through the same patternThere is no time scaleReasons for birth rates and death rates are very different in different countries
10 ActivityUsing the textbook (page 234/5 ) add notes to each stage of the Demographic Transition Model.Make sure you understand why the birth and death rate line is where it is at (E.g. why has the death rate fallen in stage 2, but the birth rate still remain high?)
11 Write the answers in your book. To finish…‘DTM’You are about to watch a clip on the DTM.It will summarise what we have learnt today.Towards the end is a quick quiz.Write the answers in your book.
12 Homework Complete the worksheet. Most questions can be completed on the worksheet – others need to be written on lined paper.
