4. Omaha, Neb. Omaha residents breathe easy thanks to unemployment that's nearly half the national average and median home prices of less than $145,000. The city's excellent air quality also helps the sighs of relief from would-be parents arriving at Methodist Hospital, which was named one of 50 Baby-Friendly Hospitals in the United States for meeting UNICEF/World Health Organization standards for supporting breastfeeding. Not only are maternal mortality rates extremely low in Omaha, but pedestrian safety rates rank among the Top 5 in the country once it's time to start pushing a stroller around.
