NYC and youth participatory budgeting 

Young people in New York now have their own participatory budget

The Civic Engagement Commission
(Commission on Civic Engagement: CEC) of the City of New York organizes a participatory budget dedicated to young people. Using theDecidim tool, they will be able to collectively decide how to allocate $100,000 to projects that meet their needs and interests and strengthen youth engagement across the city.

The project is a collaboration between Open Source Politics 🇫🇷, Digidem Lab 🇸🇪 , Coro 🇺🇸, specialists in engaging youth audiences in New York, and Spruce Technology 🇺🇸.

Where OSP comes in

For 8 months, we accompanied the Commission dedicated to Citizen Engagement (CEC) of the city of New York in the implementation of the participatory budget for young people.

In the midst of a pandemic, this first case of use in the United States has allowed us to understand and adapt to the culture of New York citizen participation inspired by community organizing . A strong emphasis is placed oninclusion by multiplying the modalities of participation, partnerships with local organizations to target marginalized audiences, systematic multilingualism etc.

In partnership with Digidem Lab, we organised a series of workshops and training sessions with the CEC team to frame each step of the participatory budget in the best possible way, to think about mobilisation mechanisms and to articulate the global project with the participation functionalities offered by the Decidim tool. This first project is part of a series of participatory budgets and a global approach to participation in New York City.

Thanks to the work of the consortium of partners and despite a pandemic context that questions traditional participatory processes, the participatory budget was successfully launched on 19 November 2020. We are delighted to welcome New York City to the Decidim community.

After organizing more than 10 participatory budgets on the Decidim tool, we have a proven structure and methodology. This first project with CEC allowed us to discover a different and innovative approach.

  • The structure of the site and the contents have been thought out and adapted for a young audience. The result: the statements are short and easy to understand, the navigation is uncluttered, the colours and visuals show the dynamism of the approach;
  • Several tools and participation channels are implemented to accommodate different audiences. SMS, video-conferencing, written proposals, short questionnaires... everything is done to ensure that everyone finds what they are looking for and that participation is pleasant and progressive;
  • Special emphasis is placed on mobilizing youth associations and collectives: participation spaces are dedicated to them, they can plan video-conferences with the organizers;
  • The young people will carry out the winning projects themselves.

How we have
deployed Decidim

We have adapted the Decidim tool to these issues:

  • The process steps ensure transparency of the process between the inhabitants and the city;
  • Documentation areas provide equal access to information ;
  • The graphic charter created by a New York graphic designer has been declined on the site;
  • The New York City Digital Identity (NYC.ID) has been implemented to facilitate connections ;
  • The platform is available in dozens of languages to enable the participation of cosmopolitan New York youth;

This project will also be an opportunity for us to test the integration with the tool we have developed. allows us to collect and analyse contributions in real time thanks to advanced statistics and machine learning.

European Metropolis of Lille: citizen participation reinvented

Métropole Lille Logo

With more than 40 consultations to its credit, MEL's participation platform has brought together thousands of citizens around its public policy co-construction projects. ???? In 2018, MEL received the consultation and participation trophy from the Gazette des communes for its #JEM Jeunes en métropole project.

The support of Open Source Politics

The first step for our team was to preparing the launch of the participatory platform. We have therefore organized several workshops to understand their participation issues and practices (charter, metropolitan context, etc.) and training to ensure a good appropriation of the platform by the MEL teams. It is on this basis that we were able to begin the work of customization of Decidim in connection with their teams :

  • Communication: to adapt Decidim to their identity;
  • ISD: for technical issues (security, RGPD, etc.)
  • Participation: to produce all the content needed to present the platform (home page, help pages etc.)

Successfully launched at the Rencontres Nationales de la participation in Lille in 2018. Our teams ensured a close follow-up to accompany the first steps in order to offer Romain De Nève, the participation officer, all the assistance required to ensure that he was able to take full control of all the possibilities of the platform. This is how we have developed a special relationship with the MEL, which today occupies an important place in our user club, where their use of the platform has been presented on several occasions. We consider them today as true partners with whom we go so far as to associate ourselves in bids for innovative projects from the European Union.

How we deployed Decidim

  • To create a single and centralizing portal for participation (public surveys, consultations, participatory mapping, etc.) thanks to the possibility of carrying out several approaches in parallel thanks to the "..." functionality. Concertations"« ;
  • To create tailor-made consultations thanks to the possibility touse several functionalities within the same approach;
  • Anchoring of participation in the territory thanks to the functionality of proposal tracking and dating;
  • Bridging digital and face-to-face participation with the meetings functionality that allows to announce events, hold a ticket office and return the exchanges;
  • Maintain an engaged community of participants by using Decidim's newsletter features.
  • Innovate using the draw module to enrich to randomly select a handful of projects to be enriched during a collective intelligence workshop.

Romain De Nève - In charge of MEL participation

" The OSP team has shown great availability for our projects. It is a very dynamic team, both in terms of responsiveness and alertness. On subjects that we think are embryonic, finally with Open Source Politics it goes very fast! We quickly go from a simple idea to a concrete solution".
