North East Lincolnshire is traditionally part of the Parts of Lindsey, Lincolnshire, in the District of the East Midlands, England, but was removed from that county in the administrative reforms of 1974 and transferred to the new county of Humberside. On the abolition of Humberside in the 1990s, North East Lincolnshire became a unitary authority. The district consists of the towns of Grimsby, Cleethorpes and Immingham, and their rural hinterland.
