The insufficiency of adequate housing and the vulnerability of the habitat are a reflection of the difficult economic and social situation that a large part of the population lives, this becomes a constant demand to find homes that have all the basic needs, according to each family, that is, If you are a single couple, they need a space where it can be expanded because in the near future they will have children, therefore they need a house with 3 to 4 rooms or at least that the rooms can be shared in addition to security, recreation spaces, it is the same For people who are single, they need an apartment that has an ideal location to move to their workplace, all these needs that become a problem to be solved to take advantage of the available land, building buildings that can meet the demands of the population.

The country has a housing stock of 1.58mm units, of which two thirds is urban. (PROFILE OF THE HOUSING SECTOR IN EL SALVADOR, 2013) Officially in 2009 the quantitative deficit was 4% and the qualitative one was 29% of the park. These figures have been reduced thanks to the financing of the acquisition of housing by the state, the production of urban land by the companies, these have given rise to 22% of the park, the legalization of the possession of 200,000 lands by the Institute of Legalization of the Ownership, the programs of various housing NGOs with 6% of the housing stock in addition to the private formal sector and social production. Self-construction is used in two-thirds of the homes. The main shortcomings of the houses are the floor materials and access to sanitation services and drinking water. To eliminate the quantitative deficit, it is necessary to invest approximately 1.3% of GDP and for the qualitative one, 1.8%.

This brings us to the initial problem which is the housing deficit, this is divided into two types:

Quantitative deficit: Lack of housing based on two conditions:

• The number of families that share the same roof and share meal preparation facilities is greater than one;

• That there are families that live in houses that cannot be improved given the low quality of the construction materials.

Qualitative deficit: This deficit does not include the dwellings considered in the quantitative deficit. The qualitative deficit is defined from three conditions:

• Poor housing conditions: homes with any of these limitations:

• Roof made of non-permanent or durable materials.

• Poor quality and durable walls and structure.

• Overcrowding: more than three people per room.

The Vice Ministry of Housing and Development

Urbano (VMVDU), determines the housing deficit according to the population and housing censuses carried out in the country, for which it is provided as Housing Deficit, the one determined by us, from the results of the last population and housing census carried out in the country, which correspond to the year 2007. This determined that the number of households that need housing (quantitative deficit) is 44,383; and the number of homes that need improvement (qualitative deficit) is 315,918. In this sense, this information will be reviewed and adjusted with the data from the next population and housing census to be carried out in our country.

The Constitution of El Salvador, in its article 119,

The construction of houses is declared of social interest. The State will ensure that the greatest number of Salvadoran families become owners of their homes. It will encourage every owner of rustic farms to provide resident workers with a hygienic and comfortable room, and adequate facilities for temporary workers; and to that end, it will provide the small owner with the necessary means. declares the construction of houses to be of social interest, so that the greatest number of Salvadoran families become owners of theirs; the declaration.

Universal Human Rights, for its part, affirms that everyone has the right to an adequate standard of living that ensures, among other things, housing.

But in countries like ours, the possibility of owning a decent home continues to be one of the main problems affecting thousands of families, whose incomes are low and their ability to save is nil. In El Salvador, it is officially recognized that the housing deficit exceeds 500 thousand homes, and that it is especially concentrated in the lower-income population strata. When housing ceases to be a right to predominantly become a business, it is restricted and determined by the speculative and exclusionary forces of the market: only those who are creditworthy have the possibility of buying a home. Poor families must settle in remote areas, lacking basic services and in precarious housing.

Among so many factors that could be mentioned, the most important is housing demand, that is, it will depend on the income that families have in our country according to EHPM 2011 It indicates the levels of poverty in the country, that is, there is a 12.20 % that their income does not even reach the minimum wage, these people live in deplorable conditions, in a newspaper article (TODAY, 2019) In total, Techo has built 3,000 emergency homes in 18 years. By 2019, 75 families will benefit from the construction of temporary homes.

According to the director, 91% of the Latin American population lives in conditions of housing deficit. Of this total, 16% do not own a home and the remaining 75% have problems with the infrastructure of their home, which can be built with materials such as plastic and sheets.

It means that in the formal sector 35% have their own home or may be candidates for a loan to buy a house since the salary can reach favorable levels, that is, a house with a bathroom and basic services in counterpart in the informal sector, an estimated 65% They have a lot or land that they are paying with small installments or that belonged to their grandparents and they obtained the land at a low cost and in colones, these houses can be made of low-quality materials with a pit bath, and land to cultivate.

In this it indicates the segmentation by housing supply, as mentioned before it depends on the income obtained by families, so their needs are not covered because they do not have the possibilities, for example, basic services can have the house with cement brick materials but They do not have water, you have to go to a nearby well, river, lagoon, in another characteristic organized construction are those companies such as the San Gabriel residential complex located in Quezaltepeque, which were made on a specific land covering the basic needs such as 3 bedrooms, 2 bathrooms, patio, kitchen and their investment was more than $ 28,500 dollars for each house, these people have to earn a salary of a minimum of $ 1,500 to be able to cover the basic expenses of as well as being able to pay for the house with a credit plan of a minimum of 30 years, which leads us poor people that their home investment to build it was at least $ 2,500 made by them themselves.
