Statistics on participation of emerging and developing countries in LHC and other experiments

International by nature, the scientific collaborations working for the Large Hadron Collider (LHC) at CERN, as well as other experiments count a small presence of emerging and developing countries. After exposing the metrics of country classification, the cases of the ATLAS and CMS Experiments will be presented, along with a brief mention of the DUNE Collaboration. Several initiatives and programmes are key game changers to grow the starting efforts. The talk gives as conclusions several recommendations on how – at both institutional and individual levels – the current landscape can be changed. More diversity and inclusion are assets in scientific endeavours, and for people from the developing world, this means nothing more than life-changing opportunities.
