1. Global population growth

2. Birth rates used to be as high as 50 per 1,000 per year, but today they tend to be between 5 per 1,000 per year and 40 per 1,000 per year. Why have they fallen? Q) Why is birth rate a better indicator of development than death rate? There are assumptions on death rate. With birth rate, family size has reduced in countries at a lesser stage of development, but parents in wealthier countries still have fewer children

3. Natural change calculations: UK BR = 10.7 per 1,000 per year DR = 10.1 per 1,000 per year NI = BR-DR = 10.7 – 10.1 = 0.6 Natural change is always expressed as a percentage (divide the answer by 10) NI = 0.06% per year Czech Republic BR = 9.0 per 1,000 per year DR = 10.6 per 1,000 per year ND = DR-BR = 10.6 – 9.0 = 1.6 ND = 0.16% per year (or -0.16%)

4. Natural change calculations: Brazil BR = DR = NI = BR-DR = NI = China BR = DR = NI = BR-DR = NI = Germany BR = DR = ND = DR-BR = ND = Nigeria BR = DR = NI = BR-DR = NI = Italy BR = DR = ND = DR-BR = ND =

5. Zero growth Population in balance. Birth rate is equal to death rate Natural decrease Death rate exceeds birth rate Exponential growth Growth rate constantly increases – shown as a J-curve graph Birth rate (BR) Number of babies born per 1,000 people per year Match the key terms: Natural change Natural increase Life expectancy The birth rate exceeds the death rate Number of years a person is expected to live, usually taken from birth Difference between birth rate and death rate (expressed as a percentage)

6. Exam Q: Is there a relationship between population change (NI or ND) and the level of economic development? (3 marks)
