Human development is not the same as quality of life

Quality-of-life coverage is conditional

A comparable life-satisfaction observation was not available in the OECD extract used for the Republic of the Congo. A missing source value is shown as unavailable.

Omit rather than guess: subjective well-being, social support, safety and time-use measures are added only when a reliable source provides a clearly defined country observation and year.
