Socio-Economic Status (SES) differences in changing affordability of tobacco products from 2011-12 to 2018-19 in India.

Tobacco use and economic disadvantage conditions of population are intricately linked. Affordability of tobacco products is influenced by socio-economic indicators like age, sex, income, education, etc. The literature measuring the affordability of tobacco products across different SES groups is scant in India. Additionally, existing literature measures affordability of tobacco products based on per capita GDP as a proxy for income. This is the first study in Indian context to report the change in affordability of tobacco products across different SES groups after adjusting for SES indicators, using individual level income data. We have calculated the change in affordability of tobacco products between year 2011-12 and 2018-19 using GDP, household income, and individual wages as proxy for income.
