Σύνοψη	A housing affordability index summarises how the cost of housing in a city or market relates to what households can pay, condensing prices, rents and incomes into a single interpretable number. The simplest forms are ratios — the median house price divided by median income, or housing outlays as a share of income — while the residual-income approach championed by Michael Stone instead asks what is left for everything else after housing is paid. Together these measures let analysts compare affordability across places and over time, flag cost-burdened populations, and track housing stress as markets shift.	A smart city index is a composite indicator that scores and ranks cities on how 'smart' they are across several dimensions — typically economy, people, governance, mobility, environment and living. Each dimension gathers many raw indicators that are normalised onto a common scale, weighted, and aggregated first into dimension scores and then into a single overall number. Prominent examples such as the European smart-cities ranking of Giffinger and colleagues and the IESE Cities in Motion Index made this six-axis framing standard, turning a sprawling, contested concept into a benchmark cities can be compared on.
