In some cultures—such as many Western countries—cleaning after defecation is generally done with toilet paper only, until the person can bathe or shower. The panic buying during COVID 19 pandemic that caused temporary shortages of toilet papers shows how important they are in the western cultures, as a household commodity. However, unconfirmed sources indicate that 70% -75% world population do not use toilet paper due to a number of reasons. Affordability is one reason that many people in the world do not use toilet paper. Toilet paper is closely linked to standard of living. The first commercially available toilet paper was invented by a New York entrepreneur named Joseph Gayetty in 1857 with the dawning of the second industrial revolution.
