    The world’s population is growing. There are now over 7 billion people in the world. During the 20th century, the population grew from 1.65 billion to 6 billion. It’s now growing at the rate of 1.1% per year. That means an increase of about 8 million per year. By 2024, the population is expected to be around 8 billion. The growth rate used to be higher. In the late of 1960s, the rate of growth was about 2%. Since then, the growth rate has declined. It estimated that the growth rate will be less than 1% by 2020. By the year 2050, the growth rate should be even less.
    Even with a declining growth rate, the population will continue to grow. But it will grow with a slower rate. In the past 50 years, the world population has more than doubled. It has doubled from around 3 billion in 1960s to more than 7 billion in 2011. The rate of growth varies by country. The growth rate in India is more than twice in China. And the growth rate in Nigeria, which is in Africa, is more than twice of India’s growth rate. Russia, on the other hand, has had a negative growth rate in some years. When a country has negative growth rate, its population is decreasing.
