Buenos Aires launched its BAData portal in 2012, growing to 400+ datasets from 35+ agencies, then adding public-works, procurement, climate and gender-violence platforms — all steered through four Open Government Partnership action plans (2016–2025).

Context

Buenos Aires' city government opened its BAData portal in 2012, one of the first city-level open-data platforms in Latin America, publishing municipal datasets on a CKAN-based system.

Activities

By the mid-2020s the portal listed more than 400 datasets contributed by over 35 city agencies, spanning health, education, transport, public works and environment, and the city extended the model into specialised platforms: BA Obras (public-works tracking), BA Compras (procurement), an Open Budget tool and a Gender Violence Map. The programme is anchored in Buenos Aires' membership of the Open Government Partnership (joined 2016): the city has delivered four OGP action plans between 2016 and 2025, each independently reviewed, with the 'Data openness and reutilisation' commitment (BUE0007) formally coordinating data production and publication across agencies, including the city's judiciary.

Results

Publicly available material documents the portal's scale and institutional continuity — over 400 datasets from 35+ agencies, sustained across four consecutive OGP action plans.

Conclusions

No independent study quantifying downstream economic or service-delivery impact of the published data was found; claims here are limited to output and process evidence.

Implementation
Indicative cost
Medium (€50k–€500k) — Ongoing municipal open-data operation built on the open-source CKAN platform, later expanded into five specialised thematic platforms; specific budget figures not disclosed in sources reviewed.
Time to results
Long (> 3 years) — Portal launched 2012; institutionalised through four consecutive OGP action plans between 2016 and 2025.
Staffing & skills
Gobierno de la Ciudad Autónoma de Buenos Aires open-data team, 35+ contributing city agency data officers, OGP co-creation civil-society participants

Conditions for success

  • Formal Open Government Partnership membership (since 2016) providing external accountability via independently reviewed action plans
  • A specific cross-agency commitment (BUE0007) formally coordinating data production and publication, including the judiciary
  • Use of an established open-source platform (CKAN) to lower technical barriers to publishing

Common failure modes

  • No independent study quantifying downstream economic or service-delivery impact of the published data was found
