In order to address various issues pertaining to the burgeoning populace, the Governing Council of the United Nations Development Programme has marked July 11th as World Population Day (WPD).
Interest on such issues is said to have gained ground when the world hit the five billion mark on July 11, 1987.
This year the theme for WPD is Universal Access to Reproductive Health Services.

Africa and Asia are the continents that will see the fastest urban population growth in the next 40 years, a UN report said earlier in the year noting that India and China are leading the surge. Earth's population is expected to roughly triple by 2050 compared to a century earlier. It stood at three billion in 1950, reached seven billion in 2011 and is likely to reach about 9.5 billion by 2050 - a rise that will occur especially in the poorest countries, according to UN estimates.
