The area of the 2.5 km² municipal area comprises a section of the plateau at the foot of the Jura in the headwaters of the Armary , a right side stream of the Aubonne . The municipality floor extends from the height of the Signal de Bougy to the northwest over the plateau to the Ruisseau des Chaux brook . The highest point of Pizy is at the level of the Signal de Bougy. In 1997, 6% of the municipal area was in settlements, 26% in forests and woodlands, 67% in agriculture and a little less than 1% was unproductive land.
With 76 inhabitants (as of December 31, 2010), Pizy was one of the smallest communities in the canton of Vaud. 87.7% of the residents are French-speaking, 9.2% German-speaking and 1.5% Italian-speaking (as of 2000). In 1900 the population of Pizy was 103 people. After the population had decreased to 60 in 1980, a slight increase has been recorded since then.
Until the second half of the 20th century, Pizy was a village dominated by agriculture . Agriculture still plays an important role as a livelihood for the population, with agriculture and cattle breeding dominating. Some other jobs are available in local small businesses and in the service sector.
The Canons of the Great Saint Bernard founded a hospice in Pizy at the end of the Middle Ages . The village belonged to the lords of Aubonne. Since the conquest of Vaud by Bern in 1536, Pizy shared the fortunes of Aubonne and in 1701 came to the Aubonne Bailiwick. After the collapse of the Ancien Régime , the village belonged to the canton of Léman from 1798 to 1803 during the Helvetic Republic, which then became part of the canton of Vaud when the mediation constitution came into force . In 1798 it was assigned to the Aubonne district.
