Background: Himalayas constitute vast mountain range in Asia spreading over 2500 Km (from east to west) at a high altitude along the northern fringes of the Indian subcontinent. The population dynamics in Himalayan domain has been immensely influenced by the variations in climatic and topographic conditions. As a result, population trends in relation to several demographic parameters are observed as population growth varies across this immense geographical contour. Objective: The present study attempts to assess and compare several crucial demographic parameters of select population groups (tribes and caste groups) residing in Himalayan province so as to provide a comprehensive picture of their demographic profile. The variation in demographic variables has also been addressed in relation to socio-economic and biological attributes. Materials and Methods: Multiple demographic determinants viz., sex-ratio, index – of – ageing, age at marriage and menarche, crude birth rate, total fertility rate, crude death rate and infant mortality rate are utilized to address demographic diversity in Himalayan population groups. Results: The sex ratio has been observed to be higher among reported population groups in Central Himalayas in comparison to Western and Eastern Himalayas. The measures of fertility – CBR, GFR and TFR – depict high values in certain population groups of Central Himalayas (Johar Bhotia, Rang Bhotia and Raji) in comparison to Western and Eastern province. Contribution: The present paper provides a comprehensive picture of the demographic profile among select Himalayan population groups. This will aid to understand the trend in demographic characteristics in the Himalayan province.
