Medellín Implements New Public Transit Subsidy Framework, Aligning With National Mobility Standards

Medellín's municipal administration announced on July 8 a restructured public transit subsidy system that will reshape how residents in lower-income districts pay for buses and the Metro cable car network starting September 1. The new framework replaces a patchwork of neighborhood-level discounts with a unified, income-based model tied to Colombia's national poverty classification system. City officials say the change will simplify enrollment and expand eligibility, though implementation poses logistical challenges for the Metropolitan Transit Authority (ATM).

The policy shift reflects pressure from both the national government and resident advocates to standardize how Medellín distributes the roughly 85 billion pesos annually budgeted for transit assistance. Under the old system, eligibility criteria varied by local administrative zone, leaving some neighborhoods with more generous discounts than others. A 2024 audit by the city's Finance Ministry found that residents in Distrito Turístico and Centro were paying up to 18 percent more than those in outlying areas for identical trips. The new framework aims to eliminate these disparities by linking subsidies directly to Colombia's SISBEN score, a standardized measure of household income and socioeconomic status used nationwide.

Who Benefits and What Changes

Residents classified in SISBEN categories 1 and 2 (the two lowest income tiers) will receive subsidized fares of 1,350 pesos per trip on the Metro system and 1,650 pesos on integrated bus routes, compared to the full fare of 3,450 pesos. This affects approximately 340,000 households in districts including Manrique, Santo Domingo Savio, San Alejo, and Arví. For a typical worker commuting daily across two zones, the change means potential savings of 27,600 pesos monthly, or about 331,200 pesos annually. ATM spokesperson Claudia Rendón acknowledged in a July 9 statement that the transition will require residents to re-register through a new digital platform launching August 15, a process that has prompted concern from community organizations unfamiliar with online systems.

Medellín's approach differs markedly from peer cities. Bogotá operates a card-based system with three subsidy tiers and allows registration through both digital and in-person centers at 47 locations. Cali implemented a needs-based model in 2023 that requires quarterly income verification. Barranquilla maintains a flat 25 percent discount for all residents earning below 1.5 times the monthly minimum wage, without income classification. Medellín's method-automatic eligibility based on SISBEN data shared between municipal and national systems-eliminates re-verification but creates dependency on a government database that community groups say excludes informal workers not yet registered.

Implementation Timeline and Remaining Questions

The city has allocated 12 billion pesos for the first six months of operation and contracted a private firm, Soluciones de Movilidad, to manage the digital enrollment platform. ATM expects 85 percent of eligible residents to complete registration by September 30, though no enforcement mechanism has been disclosed if adoption lags. The administration says the system will prevent an estimated 2.2 billion pesos in annual fraud from duplicate or ineligible cards, though this figure has not been independently verified.

Mayor's office officials indicated that a monitoring period through December 2026 will measure ridership changes and identify any equity gaps. A second phase expected in 2027 may extend subsidies to informal workers and self-employed residents based on tax filing records. For now, Medellín residents earning below the poverty line should expect to verify their SISBEN classification through the new online portal or call the city's social services line at 4-385-3000 starting August 15.
