Modelling Census Under-Enumeration - A Logistic Regression Perspective

The Scottish 2001 Census - Household Tenure

It is evident from Figure 1.2.5 (17 Kb PDF file) that public sector (or social) housing has also been previously used as a measure of deprivation. However the SIMD did not have a housing deprivation domain, solely for the reason that there is a lot of ambiguity surrounding the accurate measurement of such a domain. Nonetheless, residents in social tenures are much more likely to suffer from one or more forms of deprivation.

But although there could be a confounding effect[Footnote 1], it is still possible that tenure is an independent predictor of under-enumeration, in its own right. 

Figure 1.2.6 (18 Kb PDF file) shows that the household tenure variable is also important in determining the mobility of residents in wards. People who rent from private landlords or letting agencies are much more likely to move house. This section of the population would include not only students but also young professional adults, particularly at a time when the housing market, especially in cities, is highly competitive, making it difficult for first-time buyers to gain a foothold on the property ladder. So a lot of young professionals, for example nurses, are resident in council housing (and other social tenures) because of their affordability. However since residents in council accommodation are much more likely to be deprived, the public sector housing variable can be used to model under-enumeration.

Footnote 1

A confounding effect makes it difficult to interpret the direction of an association. It results when a predictor variable is associated with both the outcome and other predictors.
