Large areas of alluvium occupy the flood plain of the Ouse and the higher land to the south of the village and in the west is covered Boulder Clay. In the valley formed by the small stream which runs through the centre of the parish broad patches of Oolitic Limestone are exposed. (fn. 11) Baker described the soil as a cold white clay, or in some parts a brown stone brash loam, overlying limestone. (fn. 12) An earlier writer commented on the excellence of the water supply and the availability of building stone, gravel and sand, as well as 'a good vein of marble'. (fn. 13)

(fn. 18) It had increased to 367 by 1801, including 13 navigators building the canal to Buckingham, (fn. 19) and continued to rise modestly to a peak of 536 in 1821. The parish had a population of 529 in 1861, after which there was a steady decline to 362 by 1911 and only 278 fifty years later. There was then a relatively sharp increase to 378 in 1971, followed by a fall to 317 in 1981.
The modern main road from Stony Stratford to Buckingham, which leaves Watling Street at the crossroads in Old Stratford, runs through the southern part of the parish, some distance from the village of Wicken. This route, which until a bypass was built in the 1980s passed through Deanshanger, (fn. 20) was turnpiked under an Act of 1815. (fn.
