According to the Bureau of Labor Statistics, the field of dietitians and nutritionists is expected to have an average growth of 21 percent between the years of 2012 and 2022. This is a faster than average growth and demand, with an estimated 14,200 more jobs available by then.
As of 2015, Job-Outlook.CareerPlanner.com also offers data for dietitians and nutritionists, but its data is based off projections from 2006. This website claims the need for dietitians will see average growth of nine percent by 2016. However, this website also notes that job availability in coming years will depend on the desire for privatized dietitians, which has their estimate remaining cautiously low.
