Researchers have long tracked the birthweight of babies as a measure of population health.

A low birthweight, which experts define as babies born weighing less than 5.5 pounds, is associated with certain immediate and long-term health risks. For instance, low birthweight babies are more likely to experience respiratory distress and brain bleeds as newborns and develop diabetes, heart disease and high blood pressure later in life.

Today in America, about 1 in 13 newborns — 319,000 babies total — is born at a low birthweight. This statistic has fallen by more than 28,000 newborns in the last seven years, according to the KIDS COUNT Data Book. Despite this progress, American women are still more likely to have low birthweight babies relative to their counterparts in other affluent countries.

At the state level, Mississippi has the highest incidence of babies born at a low birthweight (about 1 in every 9) while Alaska has the lowest (1 in every 17).
