The effects of socioeconomic and demographic factors on the consumption of food energy, protein, vitamin A, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, and iron are examined. Socioeconomic and demographic factors analyzed are urbanization, region, race, ethnicity, sex, employment status, food stamp participation, household size, weight, height, age, and income. Several of these factors significantly affect consumption of certain nutrients. Income is an important factor affecting the consumption of vitamin A, vitamin C, and calcium. Income elasticities are relatively small at low income levels. For example, income elasticities range from 0.016 for calcium to 0.123 for vitamin C at an income level of $20,000.
