Food insecurity may be due to a range of factors. Low income and high food costs are the primary concerns; over 30 % of low-income households in 2019 were food insecure. Access to nutrition is yet another problem.

Poor urban planning, insufficient public transportation options, and small full-service supermarkets in different societies have formed food deserts. It is a term that defines societies with a lack of access to affordable and nutritious food items.
