The most common approach to measure the affordability of housing has been to consider the percentage of income that a household spends on housing expenditures. Another method of studying affordability looks at the regular hourly wage of full-time workers who are paid only the minimum wage (as set by their local, regional, or national government). The hope is that full-time workers will be able to afford at least a small apartment in the area where they work. Some countries look at those living in relative poverty, which is usually defined as making less than 60% of the median household income. In their policy reports, they consider the presence or absence of housing for people making 60% of the median income.
