Regional representation influences selections made by UPSC as it aims to maintain a diverse pool of candidates who understand various socio-cultural contexts. This emphasis on regional diversity ensures that civil services are reflective of India's multifaceted society. It facilitates representation in policy-making and administration, promoting inclusiveness. Additionally, this alignment encourages candidates from various regions to participate in the examination, leading to a broader spectrum of perspectives in governance. Results can thus exhibit a balance, ensuring fair representation across different geographical and cultural backgrounds.
