Today is world population day. The theme this year is “Calling Attention to Urgent Global Issues”. Observed on July 11, every year the day seeks to raise awareness of global population issues. Established by the United Nations Development Programme in 1989 the world population day is inspired by the public interest in Five Billion Day on July 11, 1987, approximately the date on which the world's population reached five billion people. According to the UN Development Programme the world population, at present, is over 7 billion and expected to increase up to 10.9 billion by the year 2050.
