Latest States figures show that in households earning £31,000 a year or less, most of that income comes from the old age pension.
The Household Income report is newly-published online, but the data refers to 2022, the latest available.
It shows those in the lowest fifth of households in Guernsey take home £31,000 or less.
In those homes, earnings from the old age pension make up 63%, salaries 24% and benefits 13%.
Those 65 or over, and living alone, had the lowest annual income, at £17,800.
By contrast, the highest fifth of households were earning at least £90,000 and 94% of that income came from salaries.
The Household Income report uses various forms of average, like the mathematical mean and the median.
It shows that income increased across households by around 5% over the period 2017 to 2022, but in real terms, given cost pressures, it dropped by 11%.
An interesting comparison is that between income and school attendance. It shows the wealthiest households had children attending Ladies College.
These households had a combined income of at least £100,000 a year.
Those in the lowest bracket took home £36,000 a year and had children at either the Le Rondin or Les Varendes High.
