The Demographic Transition Model and some fashion advice

How to be fashionable and a geographer 

Today we looked at a model which tries to predict how a countries population might grow or change over time. First point to remember is that a country's population will grow when the birth rate is GREATER than the death rate. This is called NATURAL INCREASE. 

THE DEMOGRAPHIC TRANSITION MODEL

This model is based on how country's like America and Britain developed over time (from way back when)  and how this affected the rate at which their population was growing. Click HERE to access today's PowerPoint and to fill in any notes you may have missed! 

Remember in an exam, it is highly unlikely that they will ask you to draw one of these from scratch. The important things for you to know about the DTM for your end of year exam is WHY the birth and death rates may change over time and HOW this will affect natural increase. You should also be able to locate where a country might sit on the demographic transition model if you are given information about their birth and death rate. 

A short-ish  post for today. Don't forget about the revision classes for this week. The topic for these is effects volcanic eruptions have on the cultural environment and how to draw awesome annotated diagrams to show this. Today at lunchtime in RR84, tomorrow morning from 9-9.30 in RR89 and Thursday lunchtime in our class room. Be there, or be uninformed about effects on the cultural environment caused by volcanic eruptions!
