Given basic nutritional information, the daily values are set for a diet of 2000 calories. 
The daily values represent the appropriate intake levels for a 2000 calorie diet. This is not to say that every person should have a 2000 calorie intake daily, but it is used by the USDA to establish a benchmark to be used. 
For example, a person who has a daily calorie intake of 2000 calories should, according to the USDA, consume about 50 grams of protein per day. These numbers can then be adjusted proportionally for each individual based on their calorie intake.
