The article discusses population growth and its impacts. It mentions that a study of around 800 rural women in Bangladesh found that economic factors are a key reason for declining birth rates and smaller family sizes in developing countries. The study showed that poor economic conditions, malnutrition and increasing mortality rates have continuously reduced population growth in Bangladesh. It states that declines in fertility, rising mortality rates and economic hardships are steadily lowering the population growth rate. The conclusion is that strong economic factors are primarily responsible for controlling population growth. Some population experts have proposed additional approaches for population control besides women's education and free access to contraception, which have not significantly reduced population growth over decades.
