The Effect of Household’s Age Structure to Waste Generation in Palembang City

Empirical facts suggested a particular household’s waste highly correlated to the specific age of the household’s inhabitant. The current study aimed to measure the effect of the household’s age structure on household waste generation. In addition to the household’s age structure, we included the food expenditure per capita, household’s average years of schooling, and the household’s net income in the waste generation model. The study used a Zero Truncated Negative Binomial Regression to estimate the effect of the variables. The findings showed the household’s age structure variable gave a better explanation of household waste generation rather than the household’s total population. The effect of the food expenditure per capita and the household’s average years of schooling variables found to be more significant when combined with the household’s age structure rather than combined with the household’s total population. In contrast, the effect of the household’s net income to waste generation found lesser. The study findings implied that the household’s age structure would be more useful in waste generation estimation, especially for the city with a relatively high fertility rate.
