Definition of Parity
Parity may be defined in various ways in relation to facilities in a building. The simplest is as equal floorspace for men's and women's washrooms. Since men's rooms include urinals, which take up less space than stalls, this still results in more facilities for men. An alternative parity is by number of fixtures within washrooms. However since women on average spend more time in washrooms more men are able to use more facilities per unit time. More recent parity regulations therefore require more fixtures for women to ensure that the average time spent waiting to use the toilet is the same for women as for men, or to equalise throughputs of men's and women's toilets.

“Although there is no universal agreement as to a definition of life, its biological manifestations are generally considered to be organization, metabolism, growth, irritability, adaptation, and reproduction.”

“No man, not even a doctor, ever gives any other definition of what a nurse should be than this—”devoted and obedient.” This definition would do just as well for a porter. It might even do for a horse. It would not do for a policeman.”
—Florence Nightingale (1820–1910)
“The U.S. is becoming an increasingly fatherless society. A generation ago, an American child could reasonably expect to grow up with his or her father. Today an American child can reasonably expect not to. Fatherlessness is now approaching a rough parity with fatherhood as a defining feature of American childhood.”
—David Blankenhorn (20th century)
