Learning Outcomes Lesson 2 & 3 of 4

• WHAT: Understand the concept of dependency ratio. • HOW: By describing some of the positive and negative effects of declining populations • WHY: So I can analyse the cases of different countries experiencing population decline and ageing populations

Connect: What is the dependency ratio? Unscramble the highlighted key terms to define this concept. â&#x20AC;˘ The endedepncy rioat is the ancebal between people are indenepdent (work and pay tax) and those who depend on them. â&#x20AC;˘ Ideally, the fewer the dependents for each independent person, the better off yecmicaonoll a untrcoy is.

Self assess your answers! The dependency ratio is the balance between people are independent (work and pay tax) and those who depend on them. Ideally, the fewer the dependents for each independent person, the better off economically a country is.

This can be expressed as a formulaâ&#x20AC;Ś Number of dependent people x 100 Number of independent people â&#x20AC;˘ Higher: Why do you think it is x 100?

Higher: What is negative growth? â&#x20AC;˘ As countries move into stage five their birth rates fall below their death rates leading to natural decrease. â&#x20AC;˘ If there is no migration to make up for the decrease then the population will shrink â&#x20AC;˘ It can lead to changes in the population structure and a change in the dependency ratio. Stick a copy of this definition into your book.

Activate: Ageing populations â&#x20AC;&#x201C; positive or negative? Sort the following statements into positives and negatives by colour coding your responses. Can you add any of your own?

People stay in work and can pass on knowledge to the next generation

Counterurbanisation leads to retirement towns having to invest to cater more for elderly

Older people have lots of money to spend and help the economy

Not enough people or wrongly skilled people to do essential jobs More grandparents around to offer

Increased taxes for those working to support pensioners

Enough jobs for everyone â&#x20AC;&#x201C; low unemployment

People have to retire Increased demand later for nursing care

Demonstrate: So what’s the problem? • Watch these clips to see why a declining population can actually be a problem. • Add any issues you haven’t got to your evaluation table. • http://news.bbc.co.uk/1/hi/world/asiapacific/8089288.stm • http://news.bbc.co.uk/player/nol/newsid_4220000/n ewsid_4221300/4221367.stm? bw=bb&mp=wm&news=1&nol_storyid=4221367&bbcws =1

Reflect: Time to discuss. What do you think? Is it really all that bad? Is this a massive problem? What could we do now to solve it?

HOMEWORK: Chance it! • Next lesson we will be looking at 4 case study examples about aging population. • Your challenge is to find out 4 different countries facing stage 5 of the DTM. • Person who matches the 4 case studies we will be studying wins!

Case Studies of an Aging Population Lesson 3 of 4

• Understand the concept of dependency ratio. • Describe some of the positive and negative effects of declining populations • Analyse the cases of different countries experiencing population decline and ageing populations

Connect: Today you will be independent researchers. â&#x20AC;˘ You must fill your thinking map with as many details as possible before the end of the lesson. â&#x20AC;˘ The more research you collect the better your case study will be for the exam! Japan

Germany

Spain

UK

Activate: How do I use this thinking tool? • In groups of four, read and summarise an article each about a country suffering from ageing populations. • Your summary should focus on what the problems that country is facing due to population decline. • Share your findings with the rest of your group – make notes in the other boxes about the other countries your group has found out about.

Reflect: Whatâ&#x20AC;&#x2122;s the solution? â&#x20AC;˘ What do you think governments should do about these problems?

Return to Learning Outcomes • All must: understand the concept of negative growth • Most should: Describe some of the positive and negative effects of declining populations • Some could: Analyse the cases of different countries experiencing population decline and ageing populations
