Prevalence is a measure of disease that allows us to determine a person's likelihood of having a disease. Therefore, the number of prevalent cases is the total number of cases of disease existing in a population. A prevalence rate is the total number of cases of a disease existing in a population divided by the total population. So, if a measurement of cancer is taken in a population of 40,000 people and 1,200 were recently diagnosed with cancer and 3,500 are living with cancer, then the prevalence of cancer is 0.118.
1 Canned food or frozen raw food, on average, costs between $400 and $1,000 per year for one to three cases of 13-ounce cans per month or for one to three 10-pound bags of frozen raw food per month.

The typical U.S. household spends 10% of its income on food. The average cost of food per month is $550 (thatâs $6,602 each year). Approximately 60% of our food budgets are spent on food eaten at home, and the rest on food consumed when weâre out and about. While food is, of course, a necessity for life, itâs often considered a fungible category in a household budget. After all, a family could dine on spaghetti or rice and beans, for pennies per meal. Or we could go out to a steakhouse and drop hundreds of dollars on dinner every night.
