The world’s population is projected to reach 8 billion people on 15 November – more than three times larger than it was in 1950. Based on current trends, the UN estimates the population could grow to about 8.5 billion by 2030, 9.7 billion by 2050 and 10.4 billion by the end of the century.
The biggest increases in population took place in the early 1960s, but the pace of growth has slowed as fertility levels decreased with the greater availability of contraception and as countries developed their economies. Increased levels of education, especially among girls, and more job opportunities for women played key roles.
On average, women are now giving birth twice, rather than five times as they were in 1950. Figures vary across regions, however. In sub-Saharan Africa, women are giving birth more than four times and in the Pacific region, or Oceania (excluding Australia and New Zealand), three times.
