This study aims to analyze the influence of rice prices, population size, and income on rice demand, as well as to determine the elasticity of rice demand in Klaten Regency. A descriptive analysis method was employed using secondary time series data over a period of 10 years (2013-2022), which included rice demand and population data. The data analysis model applied was multiple linear regression and classical assumption tests. Hypotheses were tested using t-tests, F-tests, and R-squared tests. The results indicate that: 1) Rice prices have a negative influence on rice demand, with a p-value of 0.06; 2) Population size has a positive influence on rice demand, with a p-value of 0.003; 3) Per capita income positively influences rice demand, with a p-value of 0.004; and 4) Rice demand is inelastic, as the price elasticity coefficient (0 < Ep < 1) suggests that changes in rice demand are smaller than changes in rice prices. Income elasticity (EI > 1) indicates that rice demand increases significantly with higher income levels.
