Built around the now-departed textile industry, in recent decades it has been swept up in southern New Hampshire's economic expansion as part of the Boston region. Nashua was twice named "Best Place to Live in America" in annual surveys by Money magazine. It is the only city to get the No. 1 ranking on two occasionsin 1987 and 1997. In 2007, the Morgan Quitno Press ranked Nashua as the 27th safest city in the country. The area was part of a 200-square-mile (520 km2) tract of land in Massachusetts called Dunstable, which had been awarded to Edward Tyng of Dunstable, England. Nashua lies approximately in the center of the original 1673 grant. When New Hampshire separated from Massachusetts in 1741, the state line between them was redrawn. As a consequence, the township of Dunstable was divided in two. Tyngsboro and some of Dunstable remained in Massachusetts, while Dunstable, New Hampshire was incorporated in 1746 from the northern section of the town.
