Despite its relatively large physical area, it has a comparatively small population (of less than 1 million people).
The unusually low population density that arises gives the county a very different character from the much more densely populated and urbanised counties of south-east and northern England, and is, in many ways, key to understanding the nature of the county (and perhaps even its people).
For the purposed of a general geographical classification the county can be broken down into a number of sub-regions: The highest point of the county is just to the north of the village of Normanby le Wold, in the Lincolnshire Wolds north-east of Market Rasen.
Marked by a trig point, it is 168m/551 ft high and is a Marilyn.
It extends from the Humber Estuary between Cleethorpes and Humberston at 53°33′14″N 00°00′00″W / 53.55389°N -0.00000°E / 53.55389; -0.000001 and passes through Louth and Boston before leaving the county south of Gedney Hill at 52°39′49″N 00°00′00″W / 52.66361°N -0.00000°E / 52.66361; -0.000001.
