Answer:
age
Explanation:
Market segmentation refers to dividing a large market into segments or group of potential customers that share similar characteristics between them, e.g. a demographic segmentation focuses on ethnic groups, income, education, family size, gender, age, etc.
Since generally young people use skateboards, then age is the most important demographic variable. Now we must also consider that both India and Thailand are very poor countries, with the vast majority of the population being classified as poor. So the second most important demographic variable would be income.
