UNIT 2.6 WHAT DOES THE FUTURE HOLD? (A) Predicting the world ‘s population growth o Experts think that the population will keep rising until 2100 o Rate of growth will slow down o It is hard to predict so far ahead. Experts can only estimate. (B)Why might the population fall? o There are two main factors: life expectancy and fertility rate o Copy table B (page 30) o Fertility rate in the year 1950 was 4.7 children per women and today its around 2.4. o The rate is different in different countries (C) A closer look at that rate of 2.1 o A fertility rate of 2.1 children is called the replacement fertility rate o What is replacement fertility rate? level of fertility at which a population replaces itself from one generation to the next. o 2.1 children replace the two parents when the parents die (D) Problems Ahead o In most countries the population is still rising (UK) o But, in some its already falling (Ex: Japan) o Rising and falling population can lead to problems Complete Your Turn (Page 31 Ques 6) (a)Japan – 20 years (b)(i) 4.2 children (ii) 1.4 children (c)Japan is more developed.
