The population was 1,487 at the 2020 census. It is part of the Harrisburg–Carlisle Metropolitan Statistical Area. Newport was originally known as Reider's Ferry—later Reidersville—as it was the site of an early ferry on the Juniata River operated by Paul Jr., Daniel, and John Reider until 1851. The trio had also originally laid down 54 plots and several streets. When the Juniata Division of the Pennsylvania Canal was finished in 1929, the town was officially renamed Newport.
