This study aims to: (1) analyze the social, demographic, and economic characteristics that can affect consumption expenditure per capita in North Sumatra, (2) analyze the probability of each factor influencing consumption expenditure per capita in North Sumatra. The data used were secondary data from 33 districts/cities in North Sumatra and analyzed using binary logistic regression estimation. The results show that of the 10 identified variables that can affect per capita consumption expenditure, it turns out that only 5 variables can provide estimates with the goodness of fit, namely, per capita income, number of family members, labor force participation rate, population growth, and the status of the area. Binary logistic regression estimation shows that the variable of per capita income and the variable labor force participation rate have a positive but not a significant effect on consumption expenditure per capita, while the variable of the number of family members has a positive and significant effect (α = 0.10) per capita consumption expenditure. The population growth variable has a positive but not significant effect on per capita consumption expenditure. District/city areas with population growth above the average economic growth of North Sumatra tend to be 0.356 times lower in total consumption expenditure per capita compared to districts/cities with population growth below the average economic growth of North Sumatra. The regional status variable has a positive and significant effect (α = 0.05) o per capita consumption expenditure. Regions with district status tend to have 0.001 times lower consumption expenditure per capita above the North Sumatra average compared to urban areas.
