Logement socialUn logement social est un logement destiné, à la suite d'une initiative publique ou privée, à des personnes qui ont des difficultés à se loger le plus souvent pour des raisons financières. L'expression sert aussi à désigner le secteur économique constitué par ce marché immobilier et les politiques d'économie sociale qui président à son administration. En Europe, le logement passe par diverses traditions et des histoires nationales qui toutes visent à l’encadrement des loyers et à plus ou moins d'extension du logement social.
Grand ensembleUn grand ensemble, parfois qualifié de cité ou abusivement cité HLM (car beaucoup de grands ensembles, même parmi les plus délabrés, sont des copropriétés et non des logements sociaux), est un type de forme urbaine, généralement de grande étendue, censé accueillir un grand nombre d'habitants et, dans une certaine mesure, caractérisé par l'aspect répétitif de ses bâtiments, généralement une série de barres et de tours. La composition d'un grand ensemble peut varier du tout au tout d'un contexte à l'autre.
Affordable housingAffordable housing is housing which is deemed affordable to those with a household income at or below the median as rated by the national government or a local government by a recognized housing affordability index. Most of the literature on affordable housing refers to mortgages and a number of forms that exist along a continuum – from emergency homeless shelters, to transitional housing, to non-market rental (also known as social or subsidized housing), to formal and informal rental, indigenous housing, and ending with affordable home ownership.
HousingHousing, or more generally, living spaces, refers to the construction and assigned usage of houses or buildings individually or collectively, for the purpose of shelter. Housing is a basic human need, and it plays a critical role in shaping the quality of life for individuals, families, and communities. Housing ensures that members of society have a place to live, whether it is a home or some kind of physical structure for dwelling, lodging or shelter and it includes a range of options from apartments and houses to temporary shelters and emergency accommodations.
DurabilitéLes termes durabilité ou soutenabilité sont utilisés depuis les années 1990 pour désigner une configuration de la société humaine qui lui permet d'assurer sa pérennité. Une telle organisation humaine repose sur le maintien d'un environnement vivable, permettant le développement économique et social à l'échelle planétaire et, selon les points de vue, sur une organisation sociale équitable. La période de transition vers la durabilité peut se faire par le développement durable, via la transition énergétique et la transition écologique notamment.
PolicyPolicy is a deliberate system of guidelines to guide decisions and achieve rational outcomes. A policy is a statement of intent and is implemented as a procedure or protocol. Policies are generally adopted by a governance body within an organization. Policies can assist in both subjective and objective decision making. Policies used in subjective decision-making usually assist senior management with decisions that must be based on the relative merits of a number of factors, and as a result, are often hard to test objectively, e.
Housing associationIn Ireland and the United Kingdom, housing associations are private, non-profit making organisations that provide low-cost "social housing" for people in need of a home. Any budget surplus is used to maintain existing housing and to help finance new homes and it cannot be used for personal benefit of directors or shareholders. Although independent, they are regulated by the state and commonly receive public funding. They are now the United Kingdom's major providers of new housing for rent, while many also run shared ownership schemes to help those who cannot afford to buy a home outright.
Politique publiqueUne politique publique est une intervention de l'État ou d'une autre autorité publique (banque centrale, collectivité territoriale, ...) afin d'avoir un effet sur la société ou un territoire. Les politiques publiques sont la modalité d'action de la puissance publique. Jean-Claude Thoenig définit les politiques publiques comme les . Le terme prend un sens différent selon la discipline qui l'utilise.
Agent-based modelAn agent-based model (ABM) is a computational model for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) in order to understand the behavior of a system and what governs its outcomes. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming. Monte Carlo methods are used to understand the stochasticity of these models.
Conceptual modelA conceptual model is a representation of a system. It consists of concepts used to help people know, understand, or simulate a subject the model represents. In contrast, a physical model focuses on a physical object such as a toy model that may be assembled and made to work like the object it represents. The term may refer to models that are formed after a conceptualization or generalization process. Conceptual models are often abstractions of things in the real world, whether physical or social.
