In 1989, in its decision 89/46, the Governing Council of the United Nations Development Programme recommended that, in order to focus attention on the urgency and importance of population issues in the context of overall development plans and programmes and the need to find solutions for these issues, 11 July should be observed by the international community as World Population Day.
The unprecedented decrease in mortality that began to accelerate in the more developed parts of the world in the nineteenth century and expanded to all the world in the twentieth century is one of the major achievements of humanity. By one estimate, life expectancy at birth increased from 30 to 67 years between 1800 and 2005, leading to a rapid growth of the population: from 1 billion in 1810 to 7 billion in 2012.
