In 2023, Member States unanimously agreed that the ICT DevelopmentIndex should aim to measure universal and meaningful connectivity(UMC) – the possibility for everyone to be online in optimal conditions,at an affordable cost, anywhere and anytime needed. By combininginternationally comparable indicators on access, adoption, afford-ability and infrastructure, the IDI provides a practical framework fortracking connectivity gaps and trends. The methodology in place since 2023 makes it possible to assesstrends over time. The results are encouraging. Countries across allregions and income groups have moved closer to UMC. Connectiv-ity is expanding, networks are reaching more people, affordabilityis improving, and Internet use continues to grow. At the same time,progress remains uneven, and significant disparities persist between and within countries. However, the IDI offers only a partial assessment of the state of meaningful connectivity, as theavailability of internationally comparable ICT statistics remains a challenge. Important dimensionsof meaningful connectivity – including digital skills and online safety and security – are still notadequately reflected. As this is the final edition within the current four-year validity period of the methodology, the ongo-ing revision process for the next period, starting in 2027, has also confirmed that the scope for majormethodological changes remains limited by the continued lack of internationally comparable ICTstatistics in these areas. This highlights the importance of sustained investment in ICT statistics, as well as greater effortsto strengthen statistical capacity and expand data availability in emerging areas of digital devel-opment. I would like to thank national statistical offices, ministries, regulators, operators and other stake-holders for their continued commitment to producing and reporting high-quality data. The BDT Secretariat remains fully committed to supporting Member States through standards,methodologies, technical assistance, capacity development and international cooperation. Overthe past 18 months alone, we have organised nine regional workshops attended by nearly 500participants from 101 countries, launched summer schools on evidence-based policymaking, andheld more than 30 advocacy events to promote UMC and its measurement. I am confident that, through our collective efforts, we will continue to strengthen the evidencebase needed to advance UMC and ensure that no one is left behind in the digital tra
