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 over 7 billion in 2012.
The Population Division collaborates closely with the agencies, funds, programmes and bodies of the United Nations system in the implementation of the work programme on population and in the follow-up to the International Conference on Population and Development. United Nations missions, national Government offices, United Nations offices, researchers, media representatives and the public regularly consult the Population Division regarding population estimates and projections, and information and analyses on population and development issues.
At its thirty-eighth session (E/2007/24), the Statistical Commission requested the United Nations Statistics Division and other international agencies to increase their technical assistance to national statistical offices in order to strengthen national capacity for the implementation of the 2010 World Programme on Population and Housing Censuses. In addition, the Commission requested countries to begin implementation of the revised Principles and Recommendations for Population and Housing Censuses.
UNFPA works with many partners, both within and outside the United Nations system, including Governments, non-governmental organizations, civil society, faith-based organizations, religious leaders and others, to achieve its mission. To better respond to local needs, UNFPA increasingly devotes resources to country-led efforts, placing emphasis on country-focused and country-led implementation to achieve improved results, at the same time addressing mutual accountability and strengthening harmonization and alignment.
