A decennial table for each parish is published in the Victoria County History series. By 1891 the Hundred was legally moribund, having already been de facto moribund. The population of the north-eastern six parishes has been greater than the south-west seven since an unknowable point in time between the 1831 and 1841 censuses. A summary is:
|Area name||Acreage||1801 population||1821 population||1841 population||1861 population||1881 population||1901 population|
|Seven parishes becoming in 1965 part of Surrey||13,733||5604||6720||7915||9152||14520||20888|
|Six parishes becoming in 1965 part of London||9,653||4624||6697||8672||10288||18940||32280|
|Total (Spelthorne Hundred)||23,386||10288||13417||16587||19440||33460||53168|
Relative to the county as a whole, the hundred (one of six) had 12.9% of its 181,320 acres. In 1801 it had 1.3% of the 818,129 people recorded as living in Middlesex; in 1901 it had 1.6% of the 3,585,323 people stated in the census to be living in the county (including in the County of London parts which once lay in Middlesex).
