An outgrowth of the Day of Five Billion, celebrated on 11 July 1987, World Population Day seeks to focus attention on the urgency and importance of population issues, particularly in the context of overall development plans and programmes, and the need to find solutions for these issues.
As the world population edged to 7 billion people in 2011 (up from 2.5 billion in 1950), it has had profound implications for development. A world of 7 billion is both a challenge and an opportunity with implications on sustainability, urbanisation, access to health services and youth empowerment.
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.
Today’s 1.8 billion young people are shaping social and economic realities, challenging norms and values, and building the foundation of the world’s future. Yet too many young people continue to grapple with poverty, inequality and human rights violations that prevent them from reaching their personal and collective potential.
