In France, the conventional way of measuring income inequalities uses a definition of standard of living which only covers monetary resources. Until recently, this system did not properly take into account income from financial assets and ignored the contribution made by housing to an individual’s standard of living. Measuring standard of living using a “broader” definition of property income changes the configuration of inequalities in France. Estimated additional resources, be they financial assets, which are distributed among the population in a more concentrated way than income, or the main residential property, enhance the measurement system for overall inequalities. This also alters the inequalities in standard of living between the various socio-professional categories and by age. When applying the conventional way of measuring standard of living, senior citizens have a lower average standard of living than the population average; yet bearing in mind that senior citizens have more assets than average, recognising property income improves their standard of living compared with the rest of the population.
