Iowa is the third-best state for young adults, according to a recent ranking. MoneyRates.com, an online source of information on bank rates, personal finance and investing, ranked Iowa behind North Dakota and South Dakota.  The analysis compared nine economic and lifestyle factors to determine which states offer the best conditions for young adults. Iowa was helped by having the cheapest average auto insurance premiums in the 20-to-24 age bracket, and also had a high number of fitness clubs and top-rated bars relative to the population, according to the analysis.
