BMF CP38: How social classes and health considerations in food consumption affect food price concerns


March 18, 2023

1. Project description

1.1. Main objectives

This study will examine food price concerns among urban residents across different income-based social classes. Here, health considerations in food consumption are a potential moderator.

1.2. Materials

In this research project, we use a dataset of 710 Indonesian urban residents [1]. The research project follows the Bayesian Mindsponge Framework (BMF) [2-4]. The bayesvl R package will be employed for statistical analyses [5]. Data and code snippets for this initial analysis were deposited at

1.3. Main findings

The analysis results show that people from a higher income-based social class are less likely to think that food price is a main consideration regarding their family’s food consumption, which is rather intuitive. Health considerations about food have a negative moderating effect. Figure 2 shows that while the “upper class” line is the lowest, it is also the steepest. Upper-class people who are more concerned about the health aspect of their food also have a relatively high level of food price consideration.

In Figure 2, the y-axis represents food price considerations, the x-axis represents health considerations about food, and the line color represents income-based social classes.
