This year’s World Population Day, established in 1989 and celebrated on 11 July, marks the 50th anniversary of the 1968 International Conference on Human Rights.
In this conference, family planning was affirmed a human right and it was stated that “Parents have a basic human right to determine freely and responsibly the number and spacing of their children”.
