Each column sums to 100%.
The COVID-19 study sample includes individuals who consented to providing biosamples. Observations are weighted to be state population representative in the same manner as in calculations of adjusted proportions of positive test results; the lowest age category includes everyone aged 12 to 24 years.
The CPHS panel in Karnataka is drawn from the September-December 2019 round. Observations are weighted to be state population representative; the lowest age category includes individuals aged 15 to 24 years.
The last census in India was in 2011; therefore, we use the 2021 projection produced by the Census Department. The census projection for 2021 is unweighted; the youngest age category includes those aged 15 to 29 years because the census provides only 5-year age bins.
