Abstract: Affordable houses is a major issue concerning people's livelihood. In order to give full play to the role of affordable houses, it is of particular importance to settle the access standards. At present, the access standard of affordable houses in China bases mainly on per-capita income. This paper intends to calculate and build up an access standard for affordable houses based on household income by taking the example of Xiamen as it shows demonstration effect in China. The “low income group” is identified according to a sampling survey of the packet data; through the conversion of normal distribution and uniform distribution and the Lattice Mapping method, the upper limit of income that covers 40% of all will be identified, which is the access standard of affordable houses. Based on this, a reference access standard that aims at different family scales will be worked out by further dividing the family groups and combining the index of “annual per capita income limits”.
