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.

Browsing around the internet, I came across this site which details just how much food is needed to feed one person for a year.The total estimated cost of that food is $1684. That comes to only $32 per week for an adult eating about 3,000 calories per day.Many Americans spend at least $32 a week at Starbucks alone!n a side note, he calculates that food costs have risen 5% in the first nine months of the year and 21% since January, 2008! Thatâs a significant increase. By stocking up on food and other necessary goods now, youâll have an effective hedge against continued inflation or, worst case scenario, hyper-inflation.
