Stationery is among the most essential items of every household's cultural consumption. The evidence is that although the amount spent on stationery varies with individuals' income level and has a direct relationship with whether occupations are high- or low-income, the share of stationery spending relative to individuals' total cultural spending is not a function of their occupation. For example, the largest share of stationery of cultural consumption belongs to the unskilled worker occupational group, even though this group's average stationery spending is half the spending of high-income occupations such as legislators and high-ranking officials. This means that low-income people may spend less money on stationery, but stationery has its place in their cultural consumption basket. So stationery is not a good that is dropped from the household expenditure list under the influence of economic problems or low income.
