The UDAYA Advantage

UDAYA establishes the levels, patterns and trends in the situation of younger (10-14) and older (15-19) adolescents in two Indian states. UDAYA provides robust insights on how and where to make investments in adolescents to influence their life course by the time they reach young adulthood and beyond. UDAYA will help organizations – government, bilateral, multilateral, private and non-profit – develop a better understanding of the transitions that the country‘s adolescents are making to adulthood.

UDAYA is a first-of-its-kind study on adolescents in India


UDAYA profiles multiple facets of adolescents’ lives, such as numeracy and literacy skills, health status and aspirations for the future.


UDAYA uses cross-sectional and longitudinal surveys to shed light on the factors that determine successful transitions to adulthood.


UDAYA provides state-representative evidence on the situation of young adolescents for the first time in Bihar and Uttar Pradesh.

UDAYA adds value to adolescent health and development
interventions in India


the extent to which adolescents have acquired assets that can help them make a healthy, safe and successful transition to young adulthood


factors that determine the accumulation or loss of assets and the quality of transitions from adolescence to young adulthood


important baseline indicators against which the long term impact of programs may be measured and evidence based decisions may be taken

UDAYA utilized a conceptual framework to define a set of assets that help ensure a healthy, safe and successful transition from adolescence to young adulthood. This theoretical framework draws on the transitions to adulthood framework (National Research Council [NRC] and Institute of Medicine [IOM], 2005) and the asset-building framework (Sebstad and Bruce, 2004; Bruce, Temin, and Hallman, 2012).


The UDAYA design was guided by a Technical Advisory Committee comprised of representatives from the Ministry of Health and Family Welfare, Government of India, leading NGOs working with adolescents in India and academic institutions.


UDAYA interviewed a sample of unmarried girls and boys aged 10-14 and 15-19, and married girls in ages 15-19 in 2015  in both Bihar and Uttar Pradesh.

In the first phase of the study (2015-16), the Population Council interviewed a total of:

  • 10,433 adolescents in Bihar
  • 10,141 adolescents in Uttar Pradesh


  • In 2015, UDAYA had re-interviewed a sample of unmarried girls and boys and married girls in ages 15-19, who, in 2007, were interviewed as part of the original Youth Study in Bihar.
  • In 2018, UDAYA re-interviewed a sample of unmarried girls and boys in ages 10-14 and 15-19 and married girls in ages 15-19 in Bihar and UP, who were earlier interviewed in 2015.
