World Population Day was established by the Governing Council of the United Nations Development Programme in 1989 as a way to focus attention on the urgency and importance of population issues. It was an outgrowth of the interest generated by the Day of Five Billion, which was observed on 11 July 1987.
Each year UNFPA selects a different theme to rally around. World Population Day 2010, Everyone Counts, will underscore the importance of data for development. It will foster an understanding of why reliable, disaggregated data is so crucial to progress and encourage people to participate in the census and other data collection efforts. This year, as the world population is expected to surpass 7 billion, UNFPA and partners are launching a campaign called 7 Billion Actions. It aims to engage people, spur commitment and spark actions related to the opportunities and challenges presented by a world of 7 billion people.
