Quick facts


What does “people-centred smart cities” actually mean?

It’s a shift from tech-for-tech’s-sake to tech that solves everyday problems—like reliable buses, safer streets, accessible services, and faster disaster alerts. UN-Habitat frames the 2025 focus as using data, digital tools and AI to improve life for everyone, especially vulnerable groups. urbanoctober.unhabitat.org+1

Simple examples

  • Real-time buses that include audio/visual announcements for people with disabilities.
  • Open-data dashboards that show flood risks and evacuation routes before storms.
  • Free community Wi-Fi + digital literacy clubs for low-income neighborhoods.
  • Online one-stop portals for permits, housing support, and complaints.
    (These reflect the key messages UN-Habitat is pushing for WCD 2025.) UN-Habitat

Why Bogotá?

UN-Habitat selected Bogotá to host the 2025 Global Observance, gathering city leaders, civil society and innovators to discuss people-centred smart city solutions. Expect high-profile sessions, side events and media attention around the theme. UN-Habitat+1
