The ten tools.
The structural tool output applies the everycity 10 point index plus the underlying ranked axis at the central tier.

Free at the user tier with zero login friction.

How the tools work.

The structural Numbeo cost of living index, the Mercer Cost of Living Survey, the OECD Better Life Index, the World Bank Open Data, the EIU Safe Cities Index, the Speedtest Global Index, the Glassdoor and Levels.fyi salary medians, the relevant national tax authority headline rates, and the relevant national immigration authority visa thresholds anchor the structural input cluster. The full methodology page walks the 28 ranked axes plus the data source disclosure.
