Prevalence in epidemiology is the proportion of disease found to have been affecting a particular population (typically a disease or a risk factor such as smoking or seat-belt use).
Exclusive analysis by The Daily Telegraph reveals the price of an average basket of groceries at any Coles and Woolworths supermarket in Sydney has jumped a staggering 16 per cent since 2009. That adds as much as $26 a week to the average bill.he analysis found that if a shopper today purchased the identical basket of groceries used in Choice's 2009 Supermarket Survey, they would pay more than $158 for what two years ago cost $136. CommSec economist Craig James said the average household currently spends $185 a week on food.
To answer that question we need to know just how much do people spend on food on average on both an average diet and a real food diet. According to the USDA the average family of four is spending somewhere between $544 to $1235 per month for food eaten at home.Thatâs a huge range! They break it down into 4 plans: Thrifty, low-cost, moderate, and liberal. found a few thriftyâs, a lot of low-cost or moderates, and no one who admits to spending the liberal plan :-). So for the sake of argument Iâll assume that the moderate plan is pretty average. The moderate plan for a family of four with small children is $855 per month. That is $7 a day for each person.
