Basic Questions about Population Growth Lecture part 1 There is a sense in which questions about population growth are very simple. The main factors are births, deaths and migration. Yet, the subject is complex, as I will show in this lecture. -How many people are we likely to have by the middle of the 21st century, and by the end? (Why is this question impossible to answer with confidence?) 12 billion -What does the number "70" have to do with estimates of population growth? Growth rate: 1.3%. 70/1.3= 54. This is how long it will take the population to double. -Do experts agree about the likely rates of population growth in the future? What are we to conclude from the available analyses on the subject? No. There may be downsizing in the next century.
