영국의 소득과 교육 수준에 따른 음식 소비

The types and quantities of foods we eat are influenced by our personal characteristics and also our social and economic situations. Income and educational attainment are particularly important in determining dietary behaviour. Using data from the National Diet and Nutrition Survey, we have created a graphic that illustrates how UK food consumption varies for population groups differing in level of income and education against the national average.

Key facts

• Foods appear in this graphic only if they are consumed in quantities significantly greater than that of the UK population as a whole. 
• Therefore the foods shown here are those food which stand out on a statistical basis, not the totality of the diet within each demographic group.
• The relative size of each circle indicates how much greater than average each of the foods is eaten. For example, based on this graphic you can say that people with high incomes and degrees have unusually high consumption of game birds compared to the population, but not that they necessarily eat more game birds than they eat beef & veal dishes.
• A more detailed description of the methods can be found under the graphic.

Methods

• The data for this graphic come from years 1-3 of the rolling programme of the National Diet and Nutrition Survey (NDNS). Which contains detailed data about food eaten by 1,491 adults. Because of the way NDNS is conducted, these data are a statistically representative sample of what is eaten by people in the UK.
• For each income-education category, consumption (in grams) was estimated for 68 food, beverage, and nutrient categories, as defined in NDNS.
• The estimation of intake was adjusted for the age and gender make-up of each group and the total quantity of food consumed.
• The group was plotted as a circle within the graphic if its consumption exceeded the 95% upper confidence interval of the population mean.
• The size of the circle is proportional to the difference between the level of consumption within a specific income-education category and that of the population overall.
• Within each square in the grid, similar foodstuffs are clustered together, but otherwise the relative placement of each circle does not have any meaning.
• The income categories use equivalised household income, to account for differently sized households.
