Colombia is launching a Universal Income Registry (RUI) aimed at improving the efficiency of subsidy distribution. The success of this program hinges on its methodological decisions, which will determine eligibility and exclusion criteria. Experts suggest Colombia can learn from international experiences with similar income-based programs. Effective targeting is crucial to ensure aid reaches those most in need while minimizing errors and waste. The RUI’s design will significantly impact who benefits from social assistance within the country. La Silla Vacía highlights the importance of global best practices in implementing the RUI effectively and equitably. Careful consideration of methodologies is paramount to the initiative's long-term success.
