Issued in 1965 by the United Nations Postal Administration, this 4-cent commemorative stamp highlights Population Trends and Development, a vital theme in the UN’s social and economic agenda during the 1960s. The design features three stylized human silhouettes increasing in size against a patchwork of colorful geometric fields, symbolizing demographic growth and its global impact. The UN emblem in red reinforces the organization’s commitment to planning for sustainable development. A thoughtful issue reflecting early international concern for population studies and future resource planning.
