The Townsend Material Deprivation Score was devised by Townsend et al and uses four Census variables:
- Unemployment – percentage of economically active individuals aged 16-74 who are unemployed.
- Car ownership — percentage of private households who do not have access to a car.
- Homeownership — percentage of private households not owner-occupied.
- Overcrowding — percentage of private households with more than one person per room.
