What are necessities in economics?

In economics, necessities refer to essential goods and services that individuals require for basic survival and well-being, such as food, clothing, shelter, and healthcare. These items are typically non-discretionary, meaning that people will purchase them regardless of changes in income or price. The demand for necessities tends to be inelastic, as consumers will prioritize these essentials over luxury or non-essential items. Understanding necessities is crucial for policymakers and economists when analyzing consumer behavior and designing welfare programs.
