Pavas is the ninth district of San José’s the capital of Costa Rica. It has 80 000 inhabitants on a 9.3 Km² extension. In the beginning the district’s land was used for pasture and agricultural purposes but its population grew very fast since 1960, with an increase of the urban developments in great part of its land as a result.

Variables such as: confinement, fire risk, collapse risk, and environment pollution were analyzed along with their indicators to prove the environment impact, and the variables illness and health concepts were analyzed to prove the persons grade of consciousness on this respect. This study proved a high housing and population density with great confinement of persons as well of houses. The risk of fire and soil, water and air pollution were evident.
