An Insight article on Page A15 on Monday, June 5, 'Why it pays to end the rents deadlock', incorrectly explained the median rent-to-income ratio. The cap on public housing rents makes it compulsory for any rent adjustment to ensure the median rent-to-income ratio of the population of public tenants does not exceed 10 per cent. The percentage refers to the median ratio, not to the median income of tenants. The error was made during the editing process.
