One Value is a free and user-friendly knowledge centre that aggregates information about the public investment in several social issue areas that are a priority in Portugal. These issue areas include Social Protection, Education, Health, Employment and Justice. Public investment refers to investment by the Portuguese Government.

The information made available by One Value is not static and will be updated according to the evolving nature of public policy priorities. When new and updated figures are available, those will also be incorporated in One Value.


The goal of One Value is to aggregate, in a single platform, quantitative data about public spending that is allocated to address social issues. The aim is to present data in a clear, simple, objective and meaningful way. Data made available by One Value will allow:

  • A better understanding of the allocation of public investment across social issues in Portugal;
  • Foster the development of innovative interventions that address social issues and incentivize outcome-based commissioning mechanisms.

    One Value presents qualitative and quantitative information in a structured way, making it useful in various fronts by:

  • Promoting a discussion around public policy priorities and related intervention models, as a response to social issues;
  • Developing innovative intervention models that have the potential of being more efficient and effective when compared to existing interventions;
  • Assessing the relevance of outcome metrics that are commissioned through Social Impact Bonds, an outcome-based funding mechanism.

    The information made available in One Value is segmented by social issue thematic area, according to public policy guidelines. For each thematic area, the information is displayed as following:

    1. Brief qualitative summary of thematic area;
    2. Main figures and indicators for general reference;
    3. Priority areas in terms of public policy, including relevant metrics;
    4. Unitary public investment (per capita or per occurrence) for each social issue.

    In addition, there is also a Savings Calculator across all thematic areas. The Savings Calculator allows for a simulation of potential savings in public spending according to the efficiency rates delivered by innovative interventions.


    One Value is the result of a partnership between Calouste Gulbenkian Foundation and the Portuguese Government. It was developed and implemented by MAZE - decoding impact and by Portugal Social Innovation (EMPIS) . A gestão e atualização do portal é da responsabilidade da EMPIS. All partners will remain involved and provide strategic guidance and insight.

    The information made available by One Value was validated by the public-sector entities that are responsible for the implementation of public policy in each thematic area. These include: Instituto de Segurança Social (Social Protection), Direção-Geral da Educação, Instituto de Gestão Financeira da Educação and Direção-Geral do Ensino Superior (Education), Administração Central do Sistema de Saúde (Health), Instituto de Emprego e Formação Profissional (Employment) and Direção-Geral de Reinserção e Serviços Prisionais (Justice).
