The cited overview of Sociology supplies background for the terminology and domain context used by this tool.^[1]

Flag rent-burdened households spending at least thirty percent of gross income on rent. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Rent burden (%)

Returned number in %. Rent as a share of gross income.

Rent burdened

Returned boolean. Whether the share is at least thirty percent.

• Definitions, sampling error, missing data, historical context, geographic boundaries, weighting, and classification choices can materially change social indicators and their interpretation.
• Monthly income must be at least 5e-324.
• Monthly rent must be at least 0.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Report the source population and uncertainty, inspect disaggregated data, and compare multiple accepted indicators rather than treating one summary statistic as a complete social explanation.
